The LHCb collaboration turns 30!
In August 1995 a Letter of Intent was submitted for the LHCb experiment, the world’s first dedicated B-physics experiment exploiting the unique potential of high-energy hadron-hadron collisions. This year, the…
Observation of the different behaviour of baryonic matter and antimatter.
First observation of CP violation in baryon decays – an important milestone in the history of particle physics. Yesterday, at the Rencontres de Moriond EW, the LHCb collaboration reported the…
Evidence for CP violation in Λb0→ΛK+K– decays
This week, at a CERN seminar, the LHCb collaboration presented new results that provide evidence for CP violation in Λb0→ΛK+K– decays. LHCb is an experiment designed to study physics phenomena…
Improved determination of the CKM angle γ
Today, at the 42nd International Conference on High Energy Physics, ICHEP, Prague, Czech Republic, the LHCb collaboration reported an improved determination of the CKM angle γ with a precision better…
Measurement of D0 − antiD0 mixing and CP violation in D0→K+π – decays
Today, at a CERN seminar, the LHCb collaboration reported results of the measurement of D0 − D0 mixing and CP violation in D0→K+π– decays with the full Run 2 data…
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…
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…
