  1. 56. Flavor in Finite Grand Unified Theories.
    Myriam Mondragon
    04/12/2024, 09:00
  2. 11. IMPLEMENTACIÓN DE LOS PAQUETES SARAH Y SPHENO EN MODELOS DE FÍSICA DE PARTÍCULAS
    Amelia Ruales (universidad de nariño)
    04/12/2024, 10:00
    20 minutes talk

    Nuestro trabajo se centra en la investigación y análisis de nuevos modelos teóricos en física de partículas, utilizando los paquetes de software SARAH y SPheno como herramientas principales. SARAH, implementado en Mathematica, es reconocido por su capacidad para la construcción y análisis de modelos como el Modelo Estándar, sus extensiones y en general, modelos de nueva física. SPheno permite...

  3. 2. Precise Theoretical Predictions of the Electroweak Observables
    Dr Edilson Alfonso Reyes Rojas (UDP / UNAL)
    04/12/2024, 10:55
    20 minutes talk

    In this talk, we are going to present the latest results obtained by our group regarding the theoretical predictions of electroweak observables, such as the HLBL contribution to the muon anomalous magnetic moment, the Higgs boson mass up to three-loop accuracy, and additional Higgs boson properties in both the Standard Model and its main supersymmetric extensions.

  4. 13. PARAMETRIZACIÓN DEL VÉRTICE Y DEL PROPAGADOR EN RESONANCIAS DE SPIN 3/2 PARA EL ESTUDIO EN LA DISPERSIÓN DE PIONY NUCLEON
    David Andres Pedroza Vasquez (Universidad de Antioquia)
    04/12/2024, 11:20
    20 minutes talk

    The exact formulation of quantum field theories for fundamental particles with spin $\frac{3}{2}$ represents a significant challenge in theoretical physics due to the inherent complexities in describing these systems. In particular, elastic pion-nucleon scattering involves intermediate states with spin $\frac{3}{2}$,corresponding to the $\Delta(1232)$ resonance, which underscores the...

  5. 46. Thermal and Magnetic Fluctuations in QED: Implications for Symmetry, Particle Mass, and Heavy-Ion Collisions
    Jorge David Castaño-Yepes (Pontificia Universidad Católica de Chile)
    04/12/2024, 11:45
    10 minutes talk

    In this talk, we present the implementation of the replica trick introduced by Parisi to incorporate fluctuations of external fields into the QED Lagrangian. As a first approximation, we study how magnetic and thermal fluctuations, described by white noise, induces effective interactions between fermions, exploring the consequences in various scenarios. Specifically, we demonstrate that...

  6. 4. Decay of the Higgs Boson into a Z boson - Photon Pair in the Standard Model and Beyond
    Cristian Alexis López Alvernia (Universidad de Pamplona)
    04/12/2024, 12:00
    20 minutes talk

    In this talk, I am going to discuss the computations of the decay width of the Higgs boson into a Z boson-photon pair at leading order in the Standard Model and its supersymmetric extensions.
