Abstract
Rare flavour-changing neutral-current (FCNC) decays of beauty and charm quarks, lepton flavour- and lepton-number–violating decays can provide a powerful probe for as yet unobserved virtual particles. Recent results on these topics from the LHCb experiment are reviewed. Particular attention is paid to the angular distribution of the B0 → K ∗0μ+μ− decay, where a measurement performed by LHCb shows a local discrepancy of 3.7 standard deviations with respect to the SM prediction. Using the decay B+ → K+π+π−γ, LHCb have also been able to demonstrate the polarisation of photons produced in b → s transitions. An update for the studies dedicated to decays τ+ → μ+μ−μ+ and B0(s)→ μ ± e ∓ and to the on-shell Majorana neutrinos coupling to muons in the B+ → π−μ+μ+ decay channel are also presented.
