  1. 1. Flavor anomalies with minimal models
    Prof. Eduardo Rojas (Universidad de Nariño)

    We present a model able to solve the neutral and the charged anomalies. A discussion about the low energy and LHC constraints on these processes is presented.

  2. 3. Quark mixing matrix from mass matrices with the maximum number of texture zeros
    Prof. Yithsbey Giraldo Úsuga (Universidad de Nariño)

    In this work we carry out an exhaustive study to find quark mass matrices in the Standard Model (SM), with the maximum number of texture zeros consistent with the experimental data. We found four viable configurations of five texture zeros that adjust the quark masses, the mixing angles and the CP violation phase, with deviations below 1σ level respect to the current SM best fit values. One of...

  3. 5. W' model and B meson anomalies. (Cristian Garcia)

    In recent years, evidence of Lepton Flavour Universality Violation has been observed in semi-leptonic decays associated with the charged-current transition 𝑏→𝑐𝑙𝜈 ̅ by BABAR, Belle and LHCb experiments, up to 3 standard deviations (3σ). While for the neutral-current transition 𝑏𝑏 ̅→𝑙^+ 𝑙^−, the BABAR collaboration in 2020 reported a discrepancy of 1.8σ in the leptonic decay of the ϒ(3s) meson....
