Precise determination of the Bs0−Bs0 oscillation frequency. “A phenomenon in which quantum mechanics gives a most remarkable prediction” – Richard Feynman Today, the LHCb Collaboration submitted a paper for publication…

Today, at the Rencontres de Moriond EW and at the CERN seminar, the LHCb collaboration presented an improved measurement of the very rare Bs0→ μ+μ– decay. The measured branching fraction…

Update of RK measurement Today at the Rencontres de Moriond EW conference and at a seminar at CERN, the LHCb Collaboration presented an updated measurement of the ratio RK, an…

Welcome to tetraquark discovery territory Today, the LHCb Collaboration submitted a paper for publication that reports the first observation of two tetraquarks with a new quark content ccus, decaying to…

The LHC, Large Hadron Collider, is a particle collider in which accelerated protons collide inside four large experiments. Hadrons (Greek: ἁδρός, hadrós, meaning “stout, thick”) are a class of particles…

A “smoking gun” for tightly bound tetraquarks? Today, the LHCb collaboration submitted a paper reporting the discovery of a possible tetraquark candidate, Tcccc, composed of two charm quarks and two…

Today, the LHCb collaboration submitted two papers reporting precise measurements of the properties of a mysterious particle χc1(3872), also known as the X(3872). These results have also been presented at…

Today, the LHCb collaboration submitted a paper reporting a system of three particles interpreted as three narrow excited Ξc0 – states. The Ξc0 baryon is composed of a charm-, a…

Today at the CERN seminar, the LHCb collaboration presented an analysis of the angular distributions of B0→K*μ+μ– decays. The measurement uses the same technique as a previous measurement performed on…
