Observation of a new excited charm-strange meson in decays
LHCb collaboration, R. Aaij, M. Abdelfatah +1114
A new excited charm-strange meson is observed through an amplitude analysis of the full phase space of decays. The analysis is based on a proton-proton col…
Measurement of the -boson production cross-sections in collisions at = 13 TeV in the forward region
LHCb collaboration, R. Aaij, M. Abdelfatah +1114
A precision measurement of the -boson production cross-section is performed using the decay channel, based on a sample of proton-proton collision data collected by th…
Precision measurement of the muon charge asymmetry from -boson decays in collisions at = 13 TeV in the forward region
LHCb collaboration, R. Aaij, M. Abdelfatah +1114
A precision measurement of the muon charge asymmetry from -boson decays in proton-proton collisions at = 13 TeV is presented. The analysis utilizes data corresponding…
First evidence of the decay
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1173
The first search for the decay in the range is performed using data from proton-proton collisions collected by the L…
Search for heavy neutral leptons in B-meson decays
LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1184
A search for long-lived heavy neutral leptons produced in B-meson decays and decaying to a final state is performed with data collected by the LHCb experiment in pro…
Precision measurement of CP violation and branching fractions in decays and search for the rare decay
R. Aaij, A. S. W. Abdelmotteleb, C. Abellan Beteta +1177
The decay , with a asymmetry expected to be close to zero in the Standard Model, is theoretically clean and sensitive to potential new ph…
