Today the LHCb collaboration complete the release of data collected throughout the Run I of the Large Hadron Collider at CERN. The sample made available amounts to approximately 800 terabytes…
LHCb’ s 700th publication reports interesting studies of Quantum Chromodynamics
The LHCb collaboration submitted its 700th publication! The paper reports the integrated and differential cross-section measurements of associated J/ψ and ψ(2S) production in proton-proton collisions at 13TeV, the measurement is…
Heavy Ion collisions ended 2023 data taking period
The 2023 data-taking period ended this morning at 4 am. This year LHCb started taking data on April 14 with proton-proton collisions and ended today with lead-lead heavy ion collisions.…
New observation of hypertriton and antihypertriton production in LHC proton-proton collisions
Today, at the European Physical Society Conference on High Energy Physics (EPS-HEP), the LHCb Collaboration reported its first observation of hypertritons and antihypertritons using Run 2 data collected between 2016…
Precise measurement of the unitarity triangle angle β
Today, at the CERN seminar, the LHCb collaboration presented an important result in our quest to understand the nature and origin of CP violation, which is a difference in behaviour…
Precise measurement of the CP-violating phase φs
Today at the CERN seminar the LHCb Collaboration presented the world’s best measurement of the CP-violating phase φs in Bs0 meson decays into J/ψK+K–. The phase φs plays a similar…
Test of Lepton Flavour Universality using a measurement of R(D*) with hadronic τ decays
Today, at the CERN seminar, the LHCb Collaboration presented a new test of lepton universality, one of the basic principles of the Standard Model (SM) of particle physics. This principle…
Improved lepton universality measurements show agreement with the Standard Model
Today at the CERN seminar the LHCb Collaboration presented new tests of lepton universality, one of the basic principles of the Standard Model (SM) of particle physics. This principle states…
