The LHCb Collaboration has published yesterday results of precise measurements of properties of the Z(4430)– particle which allow to determine unambiguously its exotic nature. In the traditional quark model, the…

The LHCb Collaboration has reported new important results at the Rencontres de Moriond EW Interactions and Unified Theories, March 15th – 22nd and QCD and High Energy Interaction, March 22nd…

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…

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:…

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

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,…

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…

The CMS and the LHCb Collaborations have announced today at the 2013 European Physical Society Conference on High Energy Physics, EPSHEP, Stockholm, Sweden, that the B0s→μμ decay is observed. The…

The LHCb Collaboration has just presented at the 2013 European Physical Society Conference on High Energy Physics, EPSHEP, Stockholm, Sweden, improved measurements for the rare decays B0s→μμ and B0→μμ. Last…

The LHCb Collaboration has just presented at the 2013 European Physical Society Conference on High Energy Physics, EPSHEP, Stockholm, Sweden, a first significant non-zero measurement of an observable proportional to…
