LHCb VErtex LOcator VELO
At LHCb the protons collide inside the VErtex LOcator detector (VELO). The VELO is composed of two halves, each consisting of 21 pairs of back-to-back silicon sensors, whose job is…
New charm results
The LHCb Collaboration has reported recently new important results on charm physics. (1) Ten months ago, the LHCb Collaboration presented the first observation of the D0-D0 oscillations
2013 Nobel prize in Physics
The Nobel Prize committee of the Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2013 to François Englert and Peter Higgs for “the…
Excellent performance of LHCb Ring Imaging Cherenkov (RICH) detectors
The physics results presented on this web page were obtained thanks to the excellent LHC collider performance, to the excellent LHCb data acquisition and analysis, and certainly also to the…
Matter-antimatter quantum music
A fascinating feature of quantum mechanics, in which the B0s, B0 and D0 particles turn into their antimatter partners and back, has been discussed already few times at this page,…
LHCb results hint at new physics?
The LHCb Collaboration has just published the results of a new analysis of the B0→K*0μ+μ– decay, with K*0→K+π–. These results were presented three weeks ago at the European Physical Society…
The B0s→μμ decay is observed
The CMS and the LHCb Collaborations have announced today at the 2013 European Physical Society Conference on High Energy Physics, EPSHEP, Stockholm, Sweden, that the B0s→μμ decay is observed. The…
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…
