Searching for new physics in rare kaon decays
Having previously set the world’s most restrictive limits on the dimuon decays of D0, B0 and B0s mesons, LHCb physicists have turned their attention to the search for similar decays…
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…
Measurement of the flavour-specific matter antimatter asymmetry
Physicists from the LHCb experiment have today released results that help to shed light on one of the most significant experimental discrepancies with the Standard Model of particle physics. In…
Evidence for matter antimatter asymmetry in three-body charmless B decays
LHCb physicists have presented today at the ICHEP2012 Conference in Melbourne measurements of differences between properties of matter and antimatter (CP violation asymmetry) in the charmless three-body B meson decays…
Puzzling asymmetries
The decay of the beauty meson B into an excited K meson K* and a μ+ and μ– pair is considered as an important channel for new physics search, see…
First observation of two excited states of Λb
The quark model, independently proposed by physicists Murray Gell-Mann and George Zweig in 1964 to classify the strongly interacting particles called hadrons, is very successful. In this model baryons are…
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…
