Measurement of the B0s→μμ branching fraction and search for B0→μμ decays at the LHCb experiment
The LHCb Collaboration has just presented at the 2013 European Physical Society Conference on High Energy Physics, EPSHEP, Stockholm, Sweden, improved measurements for the rare decays B0s→μμ and B0→μμ. Last…
First evidence of photon polarisation in b→sγ transition
The LHCb Collaboration has just presented at the 2013 European Physical Society Conference on High Energy Physics, EPSHEP, Stockholm, Sweden, a first significant non-zero measurement of an observable proportional to…
Observation of unexpected resonant structure in B→Kμμ decays
The LHCb Collaboration has just presented at the 2013 European Physical Society Conference on High Energy Physics, EPSHEP, Stockholm, Sweden, a first observation of unexpected resonant structure in B+→K+μ+μ– decays.…
A mystery of the beauty baryon lifetime resolved
The LHCb Collaboration has just published an important precise measurement of the Λb beauty baryon lifetime. The Λb is a particle composed of the up (u), down (d) and beauty…
