Rare decays of b-hadrons provide high sensitivity to New Physics effects. Several deviations with respect to the Standard Model predictions have been observed in recent years, leading to significant tensions in global fit analyses. It is thus crucial to update the existing measurements and study new decay modes to confirm the pattern. The latest results from LHCb and Belle on radiative, semileptonic penguin, lepton universality and lepton flavour violation decays are presented.
Rare hadronic B-meson decays allow us to study CP violation. The class of B decays final states containing two vector mesons provides a rich set of angular correlation observables to study. This article reviews some of the recent experimental results from the BaBar and Belle collaborations.
The flavour changing neutral current decays can be interesting probes for searching for New Physics. Angular distributions of the decay $mathrm{B}^0 to mathrm{K}^{*0} mu^ +mu^-$ are studied using a sample of proton-proton collisions at $sqrt{s} = 8~m
With the completion of Run~I of the CERN Large Hadron Collider, particle physics has entered a new era. The production of unprecedented numbers of heavy-flavoured hadrons in high energy proton-proton collisions allows detailed studies of flavour-chan
Analyzing $Upsilon(nS)$ decays acquired with the CLEO detector operating at the CESR $e^+e^-$ collider, we measure for the first time the product branching fractions ${cal B}[Upsilon(nS)togammachi_{b}((n-1)P_J)] times {cal B}[chi_{b}(n-1)P_J)to X_i]$
The unexpected absence of unambiguous signals of New Physics at the TeV scale at the Large Hadron Collider puts today flavour physics at the forefront. In particular rare decays of b-hadrons represent a unique probe to challenge the Standard Model pa
