φs: different properties of matter and antimatter for Bs mesons
LHCb physicists have presented today the most precise measurement of φs (the Bs mixing phase, for experts) at the Lepton Photon conference in Mumbai (India). The value of φs is…
Hunting for New Physics continues
LHCb physicists continue their search for new physics, see 8 April 2011 news for introduction. They have presented updated results during the International Europhysics Conference on High Energy Physics (EPS-HEP)…
Hunting more for New Physics
LHCb Physicists have also presented results of their search for new physics using the B0d (composed of a beauty antiquark (b) bound with a down quark d) decay into an…
Different properties of matter and antimatter
An important part of the LHCb physics programme is reserved for studying differences between the properties of matter and antimatter (CP violation for experts). At the EPS-HEP meeting in Grenoble…
Hunting for New Physics
Quantum mechanics allows energy non-conservation during a very short time, typical in particle collisions. This opens up the possibility to study signal for the existence of particles for which there…
Oscillating Strange Beauty or how matter turns into antimatter and back
Using data collected in proton–proton collisions at the LHC at a centre-of-mass energy of 7 TeV LHCb has observed a fascinating feature of quantum mechanics. The strange beauty particle (matter)…
LHCb makes first observations of interesting B0s decays
Using data collected in proton–proton collisions at the LHC at a centre-of-mass energy of 7 TeV, the LHCb experiment has observed two new rare decay modes of B0s mesons for…
Exotic mesons
In 1964 Murray Gell-Mann and George Zweig proposed the quark model (QM) in which mesons, like π mesons, are formed from quark and anti-quark pairs and baryons (like protons) from…
Beautiful atoms
The LHCb has observed beautiful atoms. The atoms are bound states of the beauty quark and anti-beauty quark. The atoms are bound by the strong force, the force which also…
From a B to Z, LHCb explores the particle alphabet
LHCb has unveiled pictures of a Z boson inside the experiment. This boson is one of the best understood of all particle species. It shows us how the forces of…
