4th Colombian Workshop on flavor physics.

15 Jun 2022, 09:00 → 17 Jun 2022, 17:00 America/Bogota

Bruno El-Bennich (Universidade Cruzeiro do Sul), Carlos Vera (Universidad del Tolima), Eduardo Rojas, Richard Beanvides, WILLIAM ANTONIO PONCE GUTIERREZ, Yithsbey Giraldo (Udenar)

The goal of the meeting is to bring together young and senior scientists, theorists
and experimentalists, to discuss recent progress in High Energy Physics. The
program of the Workshop will address a broad range of topics covering the main
areas of the particle and nuclear physics, such as:
- Standard Model and beyond
- Hadron physics
- Experimental Heavy flavors
- CP violation
- Neutrino physics

Morning: Física del sabor en la UT (Carlos Vera)

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. Since the new physics operator that modifies the charged transition also contributes to the neutral process, in this work we study the impact of these measurements on a new physics model consisting of an extra triplet of left-handed vector-bosons (W', Z') that coupled preferably to fermions of the third family. We observe that this model cannot simultaneously explain the recent measurement obtained by BABAR for ϒ(3s) and the observables given by the transition 𝑏→𝑐𝑙𝜈 ̅.
