NuCo 2022: Neutrinos en Colombia

27 Jul 2022, 08:00 → 29 Jul 2022, 18:10 America/Bogota

Mario A Acero (Universidad del Atlantico), Nicolás Bernal (Universidad Antonio Nariño), Amalia Betancur Rodriguez (EIA University (CO)), David Vanegas Forero (Universidad de Medellín), DEYWIS MORENO, Oscar Zapata (Universidad de Antioquia)

 

The second NuCo workshop (Neutrinos en Colombia) will be held on 27-29 July, 2022 at Universidad EIA (Medellín). The goal of the meeting is to provide an opportunity to discuss various aspects of Neutrino physics, like:

• Neutrino oscillations
• Long Baseline Experiments
• Reactor, Accelerator, Atmospheric and Solar Neutrinos
• Neutrino interactions and Cross sections
• Neutrino Masses and Mixing, CP Violation 
• Sterile Neutrinos
• Exotic Physics with Neutrinos
• Neutrinos in Nuclear Physics, AstroPhysics and Cosmology

Our community is a growing, active and diverse one, working on a variety of theoretical and experimental aspects of neutrinos. Hence, a broad approach to neutrino physics research is necessary given the nature of the challenge.

We expect this event to provide a platform for maximizing interactions and create new collaborations. Furthermore, we foresee a number of shorter lightning talks on specific topics. These are meant to highlight individual and/or unusual ideas and can also help increase the visibility of younger scientists.

Important dates (deadlines have been extended!):

• Registration deadline: July 22nd, 2022 (at noon)
• Abstract submission deadline: July 25th, 2022

Special Activities

We will have two sessions devoted to tutorials on some aspects on ROOT (a dedicated tool for data analysis commonly used in High Energy Physics), and on GLoBES (a software used for the simulation of neutrino oscillation experiments). Please visit the Tutorials section to see some specific requirements/suggestions in order to be prepared for the dedicated sessions.

 

In-person conference: The workshop will be held in Medellín.  
Sorry, but we are all sick of online events!

10:20 Recent results from NOvA

NOvA is a long-baseline neutrino oscillation experiment with two functionally identical detectors. The detectors are segmented calorimeters, sensitive to neutrino fluxes of various kinds. The experiment can search for oscillations into active and sterile neutrinos and probe the existence of non-standard interactions for neutrinos. The detectors are also sensitive to astrophysical neutrinos emitted during core-collapse supernova. The location on the surface of the Far Detector allows magnetic monopoles to reach it without being absorbed by the atmosphere. Meanwhile, the underground location of the Near Detector at the Fermilab campus allows the experiment to perform systematics-limited neutrino cross sections measurements. This talk will summarize the latest NOvA result on the diverse analyses completed by the collaboration.

11:20 Three-active neutrino oscillations, the global picture

Neutrino oscillations are the leading mechanism that successfully explain the neutrino flavor transition observed at dedicated detectors from several sources of neutrinos like the Sun, from interactions in the atmosphere of the Earth, and neutrinos from artificial sources such as the ones produced in reactor and accelerator-based experiments. This wealth of data is well described by neutrino oscillations within the three-active neutrino framework. In this talk the current status of this framework will be reviewed. The current precision of the measured oscillation parameters and the "known unknowns" will also be discussed. This will serve as an introduction of the goals and challenges that the future neutrino program will have to face.

15:00 Desarrollo electrónico para detectores en física de altas energías en el experimento DUNE

El Deep Underground Neutrino Experiment (DUNE) es considerado en la actualidad uno de los experimentos más importantes en el área de física de altas energías. Este experimento buscar la detección de partículas fundamentales conocidas como Neutrinos las cuales tienen unas características energéticas muy singulares y estudiar el decaimiento de protones. Se considera a los neutrinos como la partícula con masa más abundante en el universo y se espera que con si detección se pueda dar respuestas a preguntas fundamentales acerca de la naturaleza de la materia y de la evolución del universo. Este experimento que empezó a realizarse desde 2015 y que se espera que para 2027 entre en operación completa, se ha venido desarrollando en colaboración internacional con diferentes instituciones y tiene su sede principal en FERMILAB ubicado en Sanford Dakota del sur. Esta colaboración involucra a diferentes consorcios para el desarrollo y puesta en marcha de sus múltiples componentes, entre los cuales se encuentra el consorcio latinoamericano que está encargado del diseño del Photon Detection System (PDS). Este consorcio ha desarrollado para tal fin una plataforma de adquisición de datos de alto rendimiento denominada DAPHNE, la cual es una tarjeta de adquisición de datos a alta velocidad y con alta fidelidad. En esta ponencia se abordará brevemente el proceso de diseño y de puesta en marcha de este sistema de alto rendimiento para la adquisición de información de alta velocidad de los eventos producidos por la interacción de los neutrinos en el Photon Detection System desarrollado para el experimento DUNE.

15:30 The Qualitative (Potential) Applications of Artificial Mathematical Intelligence to the Deep Underground Neutrino Experiment

Classic artificial intelligence like deep learning is typically used to make sense and to understand the big amount of data obtained in huge and fundamental physical experiments like ATLAS, CMS, LHCb, NOvA, Alice, among others. On the other hand, Artificial Mathematical Intelligence (AMI) is nowadays emerging as a new global form of conceptual artificial intelligence aiming to develop physical-mathematical co-creative artificial agents which can enhance considerably the formal abstract features of mathematicians and physicists. So, in this paper, we explore some fundamental (potential) conceptual applications that AMI can have regarding the (under construction) Deep Underground Neutrino Experiment (DUNE), studying the properties and phenomenology of neutrinos. Specifically, we show how seminal pillars of AMI can enable us to produce suitable pseudo-precode of the mathematical foundational concepts modeling neutrinos, and, in that way, going a step forward towards developing an initial UMAA (Universal Mathematical Artificial Agent) specialized in helping us as a co-creative assistant in our quest of understanding more precisely the general features and phenomenology of neutrinos.

09:00 A renormalizable left-right symmetric model with low scale seesaw mechanisms

In this talk I will describe a low scale renormalizable left-right symmetric theory that successfully explains the observed SM fermion mass hierarchy, the tiny values for the light active neutrino masses and is consistent with the lepton and baryon asymmetries of the Universe, the muon and electron anomalous magnetic moments as well as with the constraints arising from the meson oscillations. In the proposed model the top and exotic quarks obtain masses at tree level, whereas the masses of the bottom, charm and strange quarks, tau and muon leptons are generated from a tree level Universal Seesaw mechanism. The masses for the first generation SM charged fermions arise from a radiative seesaw mechanism at one loop level whereas the light active neutrino masses are produced from a one loop level inverse seesaw mechanism. The model is also consistent with the experimental constraints arising from the Higgs diphoton decay rate as well as with the constraints arising from charged lepton flavor violation. I will also discuss the Z’ and heavy scalar production at a proton-proton collider.

14:00 Some aspects of Neutrino Physics

During the +90 years since their theoretical proposal, the interest on neutrinos has steadily increasing. Neutrinos play an important role in different aspects of particle physics, astrophysics and cosmology, and a large community os researchers keep looking for understanding the physics and phenomenology governing these fascinating particles. In this talk, we present an introduction to some of the relevant and active topics of neutrino physics, giving also some provocative insights on the areas where neutrino physics is being applied.

15:00 On The Effective Number of Relativistic Degrees of Freedom

It is presented an overview of the effective number of relativistic degrees of freedom $N_{eff}$, a parameter related to observations such as the abundance of light nuclei produced during Big-Bang Nucleosynthesis and temperature anisotropies in the Cosmic Microwave Background. Deviations $\Delta N_{eff}$ from the Standard Model prediction $N_{eff} = 3.045$ constitute clear signs of new physics, some of which will be commented.

15:30 Matrices con cinco ceros de textura en el sector leptónico y sus observables físicos.

En nuestro trabajo realizamos una parametrización no estándar para la matriz de mezcla unitaria en los leptones, esto con el fin de obtener los observables físicos, esto es: las tres masas de leptones cargados, dos diferencias de masas cuadradas del sector neutro, los tres ángulos de mezcla y la fase de violación CP en este sector. Para esto se consideraron estructuras especiales para las matrices de masa donde se han asumido cinco ceros de textura, tres en el sector cargado y dos en el neutro, con el objetivo de disminuir el número de parámetros espurios al mínimo necesario para explicar los observables. Estas formas fueron motivadas por las formas propuestas por Ramond-Robert-Ross en el sector de quarks.

09:30 DAPHNE in DUNE

The main goal of this talk is to give an overview of the so-called
DAPHNE(Detector electronics for Acquiring PHotons from NEutri-
nos) system, a component of the Photon Detection System (PDS) in
DUNE.

In this talk, I will give a brief introduction to the Photon Detection
System (PDS) of DUNE, far detectors in horizontal drift technology.
Nevertheless, I will include an overview of the X-ARAPUCA, cold
electronics, and the interface with DAPHNE board.

As DAPHNE board has been largely developed by Colombian in-
stitutions, like Universidad EIA, Universidad Antonio Narino, Uni-
versidad de Antioquia. A more in depth focus will be given into the
board architecture, development and implementation; in order to un-
derstand how it works, and how it matches system requirements in
DUNE.

Keywords: Photon detection, single phase, digital signal process-
ing, FPGA, Neutrinos, HDL, Migen, Python.

12:20 Measuring the Neutrino mass with next generation cosmology experiments

In this short talk, I will review the effect of massive neutrinos on cosmological observables, such as the CMB temperature anisotropies, the matter power spectrum, the growth function of structures and the weak lensing shear.
For the scales and redshifts probed by future probes, the constraints on neutrino mass will increase by even an order of magnitude, depending on the combination of probes that are considered.
I will also mention some degeneracies of the neutrino mass with modified gravity, such as f(R) theories and the possibility of couplings between neutrino masses and dark energy, that could potentially solve the current tensions in cosmology.
