Description
Plenary talks by invited speakers
High-energy gamma rays, cosmic rays, and neutrinos are messengers of violent astrophysical phenomena and probes of fundamental physics at extreme energies. Tremendous experimental advance has unlocked vast potential for progress in both directions. First, I will present the basics of high-energy particle production at astrophysical sites. Then I will showcase the main lessons learned and...
High-elevation particle detectors have opened a new observational window in Astronomy, significantly increasing the number of detected gamma-ray sources in the very- to ultra-high energy range. In particular, these instruments were able to achieve unprecedented sensitivity above 100 TeV and detected gamma-ray emission from sources up to PeV. The recent successes have all been obtained from the...
In the first part of the talk I will present our new analysis of Michel parameters in the presence of massive Dirac and Majorana neutrinos. In the second one I will summarize our improved radiative corrections for the one-meson tau decays and discuss the new physics tests (lepton universality, CKM unitarity and non-standard interactions) done with them.
The LHCb detector at the LHC is a forward spectrometer designed for the study of CP violation and rare decays of c- and b-hadrons. During Runs 1 and 2, it accumulated the largest samples of these hadrons in the world and contributed to a broad range of physics topics beyond its original purpose. The status of the experiment is discussed, together with a review of the latest physics results,...
In this talk, I will review what have we learned in neutrino physics in the last years and what we hope to learn in the coming ones.
DUNE (Deep Underground Neutrino Experiment) represents one of the most important experimental programs in the current and future scenario of neutrino physics. It will be the first mega-science project on the US sole, involving more than 1,300 physicists and more than 200 Institutions. DUNE will shade light on some of the crucial open questions in neutrino physics: the CP violation in the...
The dark matter may consist not of one elementary particle but of different species, each of them contributing a fraction of the observed dark matter density. Scenarios for multi-component dark matter based on a single ZN (N≥4) symmetry are simple and well-motivated. In this talk we will discuss the phenomenology of several two component dark matter models and analyze their detection...
ANDES (Agua Negra Deep Experiment Site) is an underground laboratory proposed to be built inside the Agua Negra road tunnel that will connect Chile (IV Region) with Argentina (San Juan Province) under the Andes Mountains. The Lab will be 1750 meters under the rock, becoming the 3rd deepest underground lab in the world, the first in South America and the largest in the Southern Hemisphere....
I will discuss the current status of the precision measurements in the Higgs sector, and
its implications for extensions of the Standard Model. I will also present the properties
of the Higgs sector within simple or well motivated extensions of the Standard Model and
the possible hints of the presence of extra Higgs bosons at the weak scale.
Almost half a century after it was predicted, the LHC delivered the Higgs boson in spectacular style. Over the next 15-20 years, the machine and its luminosity upgrade will continue to enable ATLAS and CMS to make great strides in understanding the Higgs-boson’s properties. But to fully explore the scalar sector and its possible connections with the SM’s most mysterious features, and thus to...
The CMS experiment has a broad physics program that includes precision measurements on standard model physics and searches for new physics that could explain some of the open conundrums in particle physics today. The talk will cover some of the latest results from CMS, including Higgs, Supersymmetry, dark matter, heavy resonances, Leptoquarks, among others, using data collected at the LHC...
The ATLAS experiment at the Large Hadron Collider (LHC) at CERN is a general-purpose detector designed to exploit the full discovery potential of the LHC. It is composed of a tracking detector in the innermost region around the interaction point, surrounded by calorimeters and muon chambers, featuring full 4π coverage to measure precisely the energies, directions and identity of all the...
To what extent are all astrophysical, dark, compact objects both black holes (BHs) and described by the Kerr geometry? We embark on the exercise of defying the universality of this remarkable idea, often called the "Kerr hypothesis". After establishing its rationale and timeliness, we define a minimal set of reasonability criteria for alternative models of dark compact objects. Then, as proof...
This talk will touch on several searches for new physics with gravitational wave signatures including primordial black holes, superradiance, and first order phase transitions. An overview of present and future observational approaches to detecting gravitational waves across a broad range of frequencies will also be given.
I will present the cosmological results from the Dark Energy Survey (DES) analysis of data collected over three years, the so-called DES-Y3 data, focusing on the contributions from our group. These results arise from studying three combinations of two-point angular correlation functions (the so-called 3x2pt analysis) involving the distribution of galaxies and the distortions in their images...
The Latin American Giant Observatory (LAGO) is an extended cosmic ray observatory composed by a network of water-Cherenkov detectors (WCD) spanning over different sites located at significantly different altitudes (from sea level up to more than $5000$\,m a.s.l.) and latitudes across Latin America, covering a huge range of geomagnetic rigidity cut-offs and atmospheric absorption/reaction...
CERN's Large Hadron Collider has just started Run 3 of data collection. And in 2029 it will commence the High-Luminosity (HL-LHC) phase of running - expected to last almost a decade. The amount of data collected during the HL-LHC is unprecedented in High Energy Physics. Collecting, processing, calibrating and analyzing that volume of data to the precision required is forcing the community to...
One of the main goals of the ALICE (A Large Ion Collider Experiment) collaboration is the precise study of the properties of the so-called quark–gluon plasma (QGP), the state of deconfined nuclear matter produced in heavy-ions collisions at relativistic energies. The ALICE experiment design was optimized to study this kind of collision with detectors able to identify hadrons, leptons and...
Understanding the properties of nuclear matter and its emergence through the underlying partonic structure and dynamics of quarks and gluons requires a new experimental facility in hadronic physics known as the Electron-Ion Collider (EIC). The EIC will address some of the most profound questions concerning the emergence of nuclear properties by precisely imaging gluons and quarks inside...
I will review the status of the QCD equation of state from first principles lattice QCD simulations. I will discuss a new expansion scheme, which allows to significantly extend the chemical potential coverage. I will also talk abourt phenomenological methods to extrapolate to the neutron star merger regime.
