Observation of a four-charm-quark tetraquark
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…

Chris Parkes from the University of Manchester begins tomorrow his three-year tenure as LHCb spokesperson. He takes over from Giovanni Passaleva from the Istituto Nazionale di Fisica Nucleare in Firenze.…
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…
CERN has established a task force to identify and support contributions from the Organization’s 18 000-strong global community to combat the COVID-19 pandemic. A team of physicists, engineers and technicians…
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…
