R. Aaij, A.S.W. Abdelmotteleb, C Abellan Beteta, F. Abudinén et autres

Abstract The ratio of production cross-sections of ψ(2S) over J/ψ mesons as a function of charged-particle multiplicity in proton-proton collisions at a centre-of-mass energy $$ \sqrt{s} $$ s = 13 TeV is measured with a data sample collected by the LHCb detector, …

A search for rare B → Dμ+μ− decays

R. Aaij, A.S.W. Abdelmotteleb, C Abellan Beteta, F. Abudinén et autres

Abstract A search for rare B → Dμ+μ− decays is performed using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb−1. No significant signals are observed in the non-resonant μ+μ− modes, and upper limits of …

Search for CP violation in D(s)+ → K − K + K + decays

R Aaij, ASW Abdelmotteleb, C Abellan Beteta, F Abudinén et autres

Abstract A search for direct CP violation in the Cabibbo-suppressed decay $$ {D}_s^{+} $$ D s + → K−K+K+ and in the doubly Cabibbo-suppressed decay D+ → K−K+K+ is reported. The analysis is performed with data collected by the LHCb experiment in …

Observation of the Bs0 → D *+ D *− decay

R Aaij, ASW Abdelmotteleb, C Abellan Beteta, F Abudinén et autres

Abstract The first observation of the $$ {B}_s^0 $$ B s 0 → D∗+D∗− decay and the measurement of its branching ratio relative to the B0→ D∗+D∗− decay are presented. The data sample used corresponds to an integrated luminosity of 9 fb−1 …

Search for the lepton-flavour violating decays B 0 → K *0 τ ± μ ∓

R Aaij, ASW Abdelmotteleb, C Abellan Beteta, F Abudinén et autres

Abstract A first search for the lepton-flavour violating decays B0 → K*0τ±μ∓ is presented. The analysis is performed using a sample of proton-proton collision data, collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV between 2011 and …
