First observation of photon polarisation in b→sγ transition
The LHCb Collaboration has submitted today for publication a paper reporting the first observation of photon polarisation in b→sγ transition. The full 3 fb-1 Run 1 data sample was used…
How long can beauty and charm live together?
In the Standard Model of Particle Physics the strongly interacting particles (hadrons) are composed of three quarks (baryons) or quark-antiquark pairs (mesons). There are six types of quarks, three light:…
“Underground” news
The last run 1 collisions took place at LHCb on February 2013. The proton beams should traverse again LHCb in early 2015. The period in between is called Long Shutdown…
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…
