GUT, Neutrinos, and Baryogenesis [PDF]
, 2002 It is an exciting time for flavor physics. In this talk, I discuss recent topics in baryogenesis and leptogenesis in light of new data, and implications in B and neutrino physics.

Measuring CP-Violating Observables in Rare Top Decays at the LHC [PDF]
, 2016 In this paper we consider CP-violating new-physics contributions to the decay $t \to b \bar b c$. We examine the prospects for detecting such new physics at the LHC, which requires studying the process $gg \to t (\to b \bar b c) \bar t (\to \bar b \ell ...

New physics in b → se+e−: A model independent analysis
Nuclear Physics B, 2021 The lepton universality violating flavor ratios RK/RK⁎ indicate new physics either in b→sμ+μ− or in b→se+e− or in both. If the new physics is only b→se+e− transition, the corresponding new physics operators, in principle, can have any Lorentz structure ...

International Journal of Modern Physics A, 2008 LHCb is a dedicated detector for b physics at the LHC (Large Hadron Collider). In this paper we present a concise review of the detector design and performance together with the main physics goals and their relevance for a precise test of the Standard Model and search of New Physics beyond it.

Majorana’s approach to nonadiabatic transitions validates the adiabatic-impulse approximation
Scientific Reports, 2023 The approach by Ettore Majorana for non-adiabatic transitions between two quasi-crossing levels is revisited and significantly extended. We rederive the transition probability, known as the Landau–Zener–Stückelberg–Majorana formula, and introduce ...

B physics and Quarkonia in CMS
EPJ Web of Conferences, 2017 The heavy-flavor sector offers the opportunity to perform indirect tests of beyond the Standard Model physics through precision measurements and of quantum chromodynamics (QCD) through particle production studies. A review of recent measurements on heavy

Prospects for B c + $$ {B}_c^{+} $$ → τ + ν τ at FCC-ee
Journal of High Energy Physics, 2021 This paper presents the prospects for a precise measurement of the branching fraction of the leptonic B c + $$ {B}_c^{+} $$ → τ + ν τ decay at the Future Circular Collider (FCC-ee) running at the Z -pole.

Ferromagnetism in two-dimensional hole-doped SnO
AIP Advances, 2018 Hole-doped monolayer SnO has been recently predicted to be a ferromagnetic material, for a hole density typically above 5x1013/cm2. The possibility to induce a hole-doped stable ferromagnetic order in this two-dimensional material, either by intrinsic or

Probing New Physics in b → d transitions
Journal of High Energy Physics, 2020 Recent experimental data on several observables in semileptonic B-meson decays are found to be in tension with the corresponding Standard Model predictions. Most of these deviations are related to b → c and b → s flavour changing transitions.
