LHCb thanks LHC
LHC collider has delivered at 9:50 today 2 fb-1 of luminosity to LHCb this year corresponding to about 100 million million of proton-proton collisions visible at LHCb. This was possible…
First evidence for the B0s →μμ decay
[ Branching ratio B0s →μμ = (3.2+1.5-1.2)x10-9 ] The LHCb Collaboration has presented today at the Hadron Collider Particle Symposium in Kyoto the result of the branching ratio measurement of…
Oscillating charm and beauty
[ Δmd = 0.5156 ± 0.0051 ± 0.0033 ps-1 ][ x’2 = (-0.9 ± 1.3)x10-4 ; y’ = (7.2 ± 2.4)x10-3 ] A fascinating feature of quantum mechanics has been…
Measurement of the γ angle
[ γ = (71.1+16.6-15.7)° only B±→DK decays ][ γ = 85.1° uncertainty regions [61.8,67.8]° and [77.9,92.4]°, B±→DK and B±→Dπ decays ] LHCb is an experiment set up to explore what…
Matter antimatter asymmetry in three-body charmless B decays becomes more and more interesting
[ ACP(B±→π±π+π–) = +0.120 ± 0.020 ± 0.019 ± 0.007 ][ ACP(B±→π±K+K–) = -0.153 ± 0.046 ± 0.019 ± 0.007 ] Earlier this year, LHCb physicists reported at the ICHEP2012…
Searching for new physics in rare kaon decays
[ Branching ratio K0S →μμ < 9×10-9 at 90% CL ] Having previously set the world’s most restrictive limits on the dimuon decays of D0, B0 and B0s mesons, LHCb…
First proton-lead ion collisions at LHCb
During the night, at 1:30 am, LHCb recorded the first proton-lead ion collisions at the LHC. The proton-lead physics data taking is planned to take place in January and February…
LHCb has doubled its recorded luminosity
The data sample used to obtain the LHCb results presented on this page was obtained using the integrated luminosity of 1.11 fb-1 recorded by LHCb during the 2010-2011 data taking…
1 fb-1 of luminosity has been delivered to LHCb this year
“This is great achievement considering that it comes about two months earlier than last year. Once more, the excellent performances of the machine, the skill and the commitment of the…
LHCb film shortlisted by the European Science TV and New Media Festival 2012
“LHCb – A Beauty Experiment”, a short documentary on LHCb, has been shortlisted by the European Science TV and New Media Festival 2012. The festival takes place in association with…
