  • Measurement of the CKM angle γ

    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 from the study of the CP-violating observables in beauty particle decays B±→DK± and B±→Dπ±. The particular charmed D meson decays into four charged mesons K∓π±π±π∓ […]


  • LHCb measurements help to understand possible signatures of dark matter presence in the Universe

    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 Universe. These results have been also presented recently at the Rencontres de Moriond QCD at La Thuile, Italy. The measurement is of antiproton production in […]


  • Magic beauty charmless decays

    Magic beauty charmless decays

    The largest CP violation ever observed. Today, at the Rencontres de Moriond EW, and on Tuesday, during a CERN seminar, the LHCb Collaboration reported the results of measurements of CP asymmetry in the charged charmless B meson decays into three light mesons. In these decays the b-quark is transformed into a u,d or s-quark instead […]


  • High precision measurement of the charm oscillation parameter yCP – yCPKπ using decays of D0 mesons to two light mesons

    High precision measurement of the charm oscillation parameter yCP – yCPKπ using decays of D0 mesons to two light mesons

    yCP – yCPKπ = (6.96±0.26±0.13)x10-3 Today, the LHCb Collaboration submitted for publication a paper that reports the results of the high precision measurement of the charm oscillation (mixing) parameter yCP – yCPKπ using two body D0 meson decays. The result is more precise than the current world average value by a factor of four. The […]


  • Installation of the VELO

    One half of the Vertex Locator (VELO) has landed at the LHCb experiment hall. The VELO detector will be located very tightly around the collision point. As the name suggests, we use it to determine the exact collision point.
