RARE DECAYS AT THE LHCb EXPERIMENT [PDF]
Particle and Astroparticle Physics, Gravitation and Cosmology: Predictions, Observations and New Projects, 2015 Rare decays of beauty and charm hadrons offer a rich playground to make precise tests of the Standard Model and look for New Physics at the level of quantum corrections. A review of recent LHCb results will be presented.

Measurement of the Bc +meson lifetime using Bc +→J/ψμ+νμX decays [PDF]
, 2014 The lifetime of the B+ c meson is measured using semileptonic decays having a J/ψ meson and a muon in the final state. The data, corresponding to an integrated luminosity of 2 fb-1, are collected by the LHCb detector in pp collisions at a centre-of-mass ...

The simplest B decay, precisely
Journal of High Energy PhysicsWe derive the QCD×QED factorization theorem governing the leptonic decay B − → μ − ν ¯ μ γ $$ {B}^{-}\to {\mu}^{-}{\overline{\nu}}_{\mu}\left(\gamma \right) $$ at all orders in α s and α.

Nonleptonic B-meson decays to next-to-next-to-leading order
Journal of High Energy PhysicsWe compute next-to-next-to-leading order QCD corrections to the partonic processes b → c u ¯ d $$ c\overline{u}d $$ and b → c c ¯ s $$ c\overline{c}s $$ , which constitute the dominant decay channels in standard model predictions for B-meson lifetimes ...

, 2001 We review the present status of rare B decays, focusing on inclusive decay modes and their role in our search for new physics. We also briefly discuss direct CP violation in rare B decays and the rare kaon decays $K^+\to \pi^+\nu\bar{\nu}$ and $K_L \to ...

Probing quantum decoherence at Belle II and LHCb
Journal of High Energy PhysicsWith the advent of Belle II and the LHCb upgrade, the precision measurements of various B-Physics observables are on cards. This holds significant potential for delving into physics beyond the standard model of electroweak interactions.
