First observation of $C P$ violation and measurement of polarization in $B^{+} \to I ¨ (770)^{0} K^{*} (892)^{+}$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1183

An amplitude analysis of the $B^{+} \to (I ¨ ^{+} I ¨ ^{-}) (K_{S}^{0} I ¨ ^{+})$ decay is performed in the mass regions $0.30 < m_{I ¨ ^{+} I ¨ ^{-}} < 1.10 GeV / c^{2}$ and $0.75 < m_{K^0_{\mat…

First observation of the charmless baryonic decay $B^{+} \to I^ˉ p p ˉ p$

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1186

A search for the charmless baryonic decay $B^{+} \to I^ˉ p p ˉ p$ is performed using proton-proton collision data recorded by the LHCb experiment, corresponding to an integrated…

Deuteron identification via time of flight with LHCb

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1183

It is shown that the timing capabilities of the LHCb detector operated during the LHC Run 2 can be used to identify light ion particles with momenta of a few GeV/ $c$ . This is achie…

Inclusive $B$ -meson flavour-tagging algorithm at LHCb

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1179

A new algorithm is developed to identify the flavour of neutral $B$ mesons at production in $pp$ collisions by utilising all tracks from the hadronisation process. The algorithm is…

Precision measurement of the $I^_{b}^{0}$ baryon lifetime

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1176

A sample of $pp$ collision data, corresponding to an integrated luminosity of 5.4 fb $^{- 1}$ and collected by the LHCb experiment during LHC Run 2, is used to measure the ratio of t…
