28. Exploring Inelastic Dark Matter Signatures with DUNE

Gustavo Adolfo Castrillon Yepes (University of Antioquia)

05/12/2024, 15:00

20 minutes talk

Inelastic dark matter is a topic of great interest due to its rich phenomenology, which allows for the exploration of particles in the sub-GeV scale. Our study focuses on an inelastic model involving two Majorana fermions, χ1 and χ2, mediated by a dark photon and a dark Higgs boson, the latter being responsible for the generation of mass in the dark sector. Given the scale, we concentrated on...

12. Quality Control of Mass-Produced GEM Detectors for the CMS ME0 Muon Upgrade

Mr Anderson Alexis Ruales Barbosa (Universidad de Antioquia (CO))

05/12/2024, 15:25

20 minutes talk

The series of Large Hadron Collider upgrades, culminating in the High-Luminosity Large Hadron Collider, will significantly expand the physics program of the Compact Muon Solenoid (CMS) experiment. However, these upgrades will also create more challenging experimental conditions, affecting detector operations, triggering, and data analysis [1]. During Run 3, the LHC is designed to achieve an...

55. Exotics searches status at the CMS Experiment

31. Estudio sistemático de la estructura de jets de b y b barra a bajo pt

Juan Montoya (Universidad de Antioquia's estudent), TOMAS SOSA GIRALDO

05/12/2024, 17:15

10 minutes talk

Estudio de los jets a bajo pt pertenecientes al proceso $\text{p p > b b~}$ excluyendo a $h$ y $z$ como mediadores, haciendo uso de MadGraph y ROOT.

32. Caracterización de fibras ópticas de un detector de partículas usando IA

Prof. Jorge Eduardo Ossa Sánchez (Universidad de Medellín, Estudiante Doctorado en Modelación y Computación Científica)

05/12/2024, 17:30

10 minutes talk

Para transmitir señales ópticas con alto porcentaje de eficiencia se requiere que la fibra óptica tenga un mínimo de defectos en su estructura.
A través de este análisis se pretende exponer un proceso basado en inteligencia artificial que recibe como argumento una imagen del corte transversal de una fibra óptica y la clasifica como apta o no apta para trasmitir la señal de acuerdo a la...

43. Tau polarization in Z to ditau decays

Jose Antonio Reyes Vega (Universidad de los Andes (CO))

05/12/2024, 17:45

20 minutes talk

Taus are third-generation leptons with a short lifetime, and their decay products offer a unique opportunity: by analyzing the kinematic distributions of these products, it is possible to reconstruct variables that reveal tau polarization. Polarization, which is directly linked to helicity, is a crucial observable that distinguishes between right- and left-handed particles. Moreover, with...

14. On the Effects of Interference in BSM Production and Detection of Two Tau leptons at the LHC

Cristian Rodriguez (Universidad de los Andes)

05/12/2024, 18:10

20 minutes talk

The study of third-generation fermion channels at the LHC has gained increasing importance, particularly in light of potential excesses observed in the data. This work is a phenomenological study aimed at establishing and distinguishing the effects of different types of BSM particles that can produce an posible excesses in channels with two taus in the final state. These include resonant...
