  1. 30. Two Texture Zeros for Dirac Neutrinos
    Richard Benavides
    03/12/2024, 14:30
    20 minutes talk

    A systematic study of the neutrino mass matrix Mν with two texture zeros under the assumption that neutrinos are Dirac particles, is carried through in detail. Our study is done without any approximation, first analytically and then numerically. Current neutrino oscillation data are used in our analysis. Phenomenological implications are studied.

  2. 8. Model with Lmu-Ltau symmetry and Majorana Neutrinos
    DAVID ALEJANDRO SUAREZ ROLDAN

    20 minutes talk

    We implement a model with a new non-universal Lmu-Ltau gauge symmetry that contains a Dark matter candidate and a scotogenic realization of a Majorana operator for neutrino masses. and we analyze its phenomenological and theoretical constraints.

  3. 33. Análisis del problema del momento magnético anómalo del muón en un modelo U(1)d adicional al Modelo Estándar.

    20 minutes talk

    En este trabajo, se presenta un análisis detallado al problema del momento magnético anómalo del muón en el contexto de un modelo teórico extendido que incorpora un grupo de simetría $U(1)_d$ adicional al Modelo Estándar de la física de partículas.

    El momento magnético es un parámetro fundamental netamente cuántico que mide que tan sensible es el espín de una partícula a un campo...

  4. 26. Short Distance Constraints to the Hadronic Light-by-Light contribution to the anomalous magnetic moment of the muon
    Daniel Melo

    20 minutes talk

    We studied the Hadronic Light-by-Light (HLbL) contribution to the muon anomalous magnetic moment. Upcoming measurements will reduce the experimental uncertainty of this observable by a factor of four, therefore the theoretical precision must improve accordingly to fully harness such experimental breakthrough. With regards to the HLbL contribution, this implies a study of the high-energy...

  5. 39. Non Abelian Chern-Simons on the Null Plane
    German Ramos
    03/12/2024, 16:00
    10 minutes talk

    We present a canonical quantization for Non abelian Chern-Simons on
    the Null Plane coordinates using the Dirac procedure and the
    Faddeev-Jackiw formalism. The constraint structure when using
    null-plane coordinates is considered and the gauge conditions are
    determined.
