Measurement of the CKM angle γ in the B0DK0 channel using self-conjugate DK0Sh+h decays / LHCb Collaboration
A model-independent study of CP violation in B0DK0 decays is presented using data corresponding to an integrated luminosity of 9fb1 collected by the LHCb experiment at centre-of-mass energies of s=7,8 and 13 TeV. The CKM angle γ is determined by examining the distributions of signal decays in phase-space bins of the self-conjugate DK0Sh+h decays, where h=π,K. [...]

A search for rare BDμ+μ decays / LHCb Collaboration
A search for rare BDμ+μ decays is performed using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb1. No significant signals are observed in the non-resonant μ+μ modes, and upper limits of B(B0¯D0μ+μ)<5.1×108, B(B+D+sμ+μ)<3.2×108, B(B0s¯D0μ+μ)<1.6×107 and fc/fuB(B+cD+sμ+μ)<9.6×108 are set at the 95 % confidence level, where fc and fu are the fragmentation fractions of a B meson with a c and u quark respectively in proton-proton collisions.

Λ+c polarimetry using the dominant hadronic mode / LHCb Collaboration
The polarimeter vector field for multibody decays of a spin-half baryon is introduced as a generalisation of the baryon asymmetry parameters. Using a recent amplitude analysis of the Λ+cpKπ+ decay performed at the LHCb experiment, we compute the distribution of the kinematic-dependent polarimeter vector for this process in the space of Mandelstam variables to express the polarised decay rate in a model-agnostic form. [...]

The first observation and study of two new baryonic structures in the final state Ξ0bπ+π and the confirmation of the Ξb(6100) state in the Ξbπ+π decay mode are reported using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb1. In addition, the properties of the known Ξ0b, Ξb and Ξb resonances are measured with improved precision. [...]

Search for CP violation in the phase space of D0ππ+π0 decays with the energy test / LHCb Collaboration
A search for CP violation in D0ππ+π0 decays is reported, using pp collision data collected by the LHCb experiment from 2015 to 2018 corresponding to an integrated luminosity of 6fb1. An unbinned model-independent approach provides sensitivity to local CP violation within the two-dimensional phase space of the decay. [...]
