The rarest B decay ever observed
The LHCb collaboration has made the first observation of the decay B+ → π+μ+μ–. With a branching ratio of about 2 per 100 million decays, this is the rarest decay…
LHCb looks forward to electroweak physics
Measurements of the production of W and Z bosons, see 10 June and 22 July 2010 news, allowed LHCb physicists to explore electroweak physics, see CERN Courier article. click the…
LHCb strongly squeezes SUSY parameter space
Results presented by the LHCb Collaboration at the Rencontres de Moriond EW and QCD conferences allowed theorists to squeeze strongly the parameters of supersymmetric extensions of the Standard Model (SUSY),…
B0d →K*μμ, a first measurement of the zero-crossing point
LHCb physicists have continued their search for physics beyond the Standard Model using the B0d decay into a K* meson (an excited kaon), and a μ+ and μ–. New physics…
A first measurement of the CP asymmetry in the decay B0s →K+K-
In a fascinating world of quantum mechanics the strange beauty particle (matter) B0s turns into its antimatter partner about 3 million million times per second (3*1012), see 15 March 2011…
Search for New Physics, an important milestone
The LHCb collaboration has announced today at the Rencontres de Moriond EW conference one of the most hotly anticipated results from the LHC. LHCb has shown that the frequency with…
Heavier strange-beauty lives longer and improved φs measurements
LHCb physicists have reported today at the Rencontres de Moriond EW conference important progress in measurement of the difference between properties of matter and antimatter for the strange beauty Bs…
First evidence for CP violation in the decays of Bs mesons
Measurement of CP violation, which describes differences between the properties of matter and antimatter, is a very important goal of LHCb. CP violation is well established in the K0 and…
LHCb looks to the future
After a very succesful 2011 data taking period the LHCb Collaboration is preparing next year’s operation. The first 2012 collisions should be observed in April. At the same time LHCb…
CP violation in charm decays
The LHCb Collaboration has presented today at the Hadron Collider Particle Symposium in Paris possible first evidence for CP violation, the difference between behaviour of matter (particles) and antimatter (antiparticles),…
