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 ...

Top-quark decay into ϒ-meson

open access: yesPhysics Letters B, 2021
The calculation of the partial width of the rare t-quark decay into ϒ-meson, W-boson and b-quark (t→ϒWb) is presented. The branching ratio equals Br(t→ϒWb)=1.3×10−5 that make possible searches for this rare t-quark decay at LHC.

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.
