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…
LHCb data released to the public
Today the LHCb collaboration has, for the first time, released its data to the public allowing research to be conducted by anyone in the world. All scientific results from the…
New test of lepton universality using the first simultaneous measurement of R(D) and R(D*) observables at LHCb
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…
The first evidence for CP violation in a specific charm hadron decay
The International Conference on High Energy Physics, ICHEP 2022, ended today in Bologna (Italy). At this conference, the LHCb collaboration reported a new measurement of the CP-violating asymmetry, ACP, in…
Observation of a strange pentaquark, a doubly charged tetraquark and its neutral partner.
Today, at the CERN seminar, the LHCb Collaboration reported the observation of a strange pentaquark, a doubly charged tetraquark and its neutral partner. These results will also be presented at…
