Matter-antimatter quantum music
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,…
LHCb results hint at new physics?
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 B0s→μμ decay is observed
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…
