Exchanging a virtual $\tau$ between a $\mu\to \tau$ and a $\tau\to e$ flavour changing vertex results in $\mu\to e$. This talk will discuss the sensitivity of $\mu\to e$ observables to products of $\mu\to \tau \times \tau \to e$ interactions in the Standard Model Effective Field Theory and in a $Z'$ model. We will show that the exceptional sensitivity of upcoming $\mu\to e$ experiments could...
The Mu2e experiment, based at Fermilab, will search for the coherent, neutrino-less conversion of a negative muon into an electron in the field of an aluminum nucleus, an example of Charged Lepton Flavor Violation (CLFV). Observation of CLFV at Mu2e would be an unambiguous signal of physics beyond the Standard Model (BSM). Mu2e aims to improve upon the previous upper limit by four orders of...
The Mu2e experiment at Fermilab will search for the CLFV neutrinoless coherent conversion of muon to electron, in the field of an Al nucleus. The experimental signature of the process is a monochromatic conversion electron (CE) with 104.97 MeV/c energy. CE-like electrons could also come from background processes like the cosmic muons, Decay in Orbit (DIO) of muons stopped in the Stopping...
Mu2e-II experiment is a proposed upgrade to the Mu2e experiment (currently in its construction phase) for the purpose of discovering charge lepton flavor violation (CLFV) through muon to electron conversion. The upgrade will use the increased beam capabilities of Fermilab’s PIP-II project to achieve another order of magnitude improvement over the existing Mu2e goal of $10^4$ to the previous...
Semileptonic $b$-hadron decays proceed via charged-current interactions and provide powerful probes for testing the Standard Model and for searching for New Physics effects. The advantages of studying such decays include the large branching fractions and reliable calculations of the hadron matrix elements. In this contribution, LHCb measurements on CKM paramenters and test of new physics will...
In the SM, the electroweak bosons couple to the three lepton families with the same strength, the only difference in their behaviour being due to the difference in mass. In recent years, some deviations have been found in measurements of the ratios of branching fractions for $b$-hadrons decaying into final states with different lepton flavours. This talk presents recent results of lepton...
