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…

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…

Observation of the rare baryonic decay and measurement of its weak decay parameter

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1182

The first observation of the decay is presented, using proton-proton collision data collected by the LHCb experiment between 2016 and 2018 at a cent…

First observation of the decay and evidence for the decay

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1187

A search is presented for the two-body charmed baryonic decays , using a data sample collected by the LHCb experiment during…
