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…

Today at the Winter Meeting on Nuclear Physics, Bormio, Italy, the LHCb collaboration announced the discovery of a new beauty baryon particle. The new particle is observed in the Λb0π+π–…

First observation of excited Ωb– states. Today, the LHCb collaboration submitted a paper reporting a new system of four particles interpreted as four narrow excited Ωb– states. As in many…

Today the LHCb Collaboration submitted for publication a measurement of the ratio RpK. This tests a principle of the Standard Model of particle physics known as “lepton universality“, which states…

The LHCb collaboration has submitted its 500th publication! The first LHCb paper was submitted in August 2010, and since then 50 to 70 papers were submitted per year. All LHCb…
