Year: 2019

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 LHC Run 2 ended a year ago. The LHCb experiment has been largely dismantled and an almost completely new detector is under construction in these very days: a new…

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…

The LHCb Collaboration presented several new interesting results at the Quark Matter 2019 conference in Wuhan, China. Among them was a study of how the production rate of the exotic…

The LHCb Collaboration presented interesting new results at the International Conference on Kaon Physics 2019 in Perugia, Italy, and at the International Conference on B-physics at frontier machines, Beauty 2019…

Today at the EPS-HEP conference, the LHCb collaboration announced the discovery of two new beauty baryon particles. These particles are interpreted as excited states of the Λb0 baryon. The new…
