Rare Decays [PDF]

open access: yesEPJ Web of Conferences, 2013
This review presents recent results on key measurements of rare B and τ decays performed at the LHC and the TeVatron. Its main focus lies on recent measurements of the decay B(s)0 → µ+µ− at the two colliders and of angular observables for the decay B0 ...

Theory of rare K decays [PDF]

open access: yesEPJ Web of Conferences, 2018
I review rare kaon decays. I introduce the flavor problem and possible solutions. Very rare kaon decays like K → πvv¯ are very important to this purpose: we study also K → πl+l-, K → ππee where chiral dynamics is important to disentangle short distance ...

RARE b DECAYS [PDF]

open access: yesInternational Journal of Modern Physics A, 1995
Rare b decays provide a unique opportunity to measure Standard Model parameters and probe beyond the Standard Model. We review here the experimental progress made in measuring these decays, and the importance of future measurements, including the possible observation of CP violation.

Rare decays: Experiments

open access: yesZeitschrift für Physik C Particles and Fields, 1992
The experimental status of generation number violating muon and kaon decays is reviewed. We concentrate on three experiments with a large PSI contribution, neutrinoless muon-electron conversion, muonium-antimuonium conversion and the decay K+ --> pi+mu(e).

Rare Decays at LHCb

open access: yesMoscow University Physics Bulletin, 2022
The Standard Model (SM) of particle physics is the most advanced theory describing the behaviour and interactions of elementary particles. Despite passing an impressive amount of experimental tests, several deviations from the SM predictions have been observed in recent years in measurements of observables related to rare $b$-hadron decays, prompting ...

Rare φ decays

open access: yesThe European Physical Journal C, 2003
The Kloe experiment has collected an integrated luminosity ~ 500 pb–1 up to now, which means ~ 1.65×109 φ decays. The huge amount of events allowed us to measure rare φ decays. We measured the radiative decays of the φ meson into π0, η and η′(958). These measurements are relevant to assess the mixing in the pseudoscalar nonet as well as to evaluate the
