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 $μ^{\pm} π^{\mp}$ final state is performed with data collected by the LHCb experiment in pro…

Measurement of the top-quark production cross-section and charge asymmetry at LHCb

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1173

The first measurements of the top- and antitop-quark differential production cross-sections and the top-quark charge asymmetry in the forward region are presented, using proton-pro…

Precision measurement of CP violation and branching fractions in $B^{\pm} \to K_{S}^{0} h^{\pm}$ $(h = π, K)$ decays and search for the rare decay $B_{c}^{\pm} \to K_{S}^{0} K^{\pm}$

R. Aaij, A. S. W. Abdelmotteleb, C. Abellan Beteta +1177

The decay $B^{\pm} \to K_{S}^{0} π^{\pm}$ , with a $C P$ asymmetry expected to be close to zero in the Standard Model, is theoretically clean and sensitive to potential new ph…
