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…

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…
Measurement of the CKM angle γ
The largest CP violation ever observed. This week, at the 10th Annual Large Hadron Collider Physics Conference, LHCP2022, LHCb presented results of the determination of the Cabibbo–Kobayashi–Maskawa (CKM) angle γ…
LHCb measurements help to understand possible signatures of dark matter presence in the Universe
Today, at the Quark Matter conference at Kraków, Poland, the LHCb Collaboration presented results of an analysis which may have significant consequences for the search for “dark matter” in the…
