Search for prompt production of pentaquarks in charm hadron final states / LHCb Collaboration
A search for hidden-charm pentaquark states decaying to a range of ΣcD¯ and Λc+D¯ final states, as well as doubly-charmed pentaquark states to ΣcD and Λc+D, is made using samples of proton-proton collision data corresponding to an integrated luminosity of 5.7fb1 recorded by the LHCb detector at s=13TeV. Since no significant signals are found, upper limits are set on the pentaquark yields relative to that of the Λc+ baryon in the Λc+pKπ+ decay mode. [...]

Observation and branching fraction measurement of the decay ΞbΛb0π / LHCb Collaboration
The decay ΞbΛb0π is observed using a proton-proton collision data sample collected at center-of-mass energy s=13 TeV with the LHCb detector, corresponding to an integrated luminosity of 5.5 fb1. This process is mediated by the suu¯d quark-level transition, where the b quark in the Ξb baryon is a spectator in the decay. [...]

Measurement of the Z boson production cross-section in pp collisions at s=5.02 TeV / LHCb Collaboration
The first measurement of the Z boson production cross-section at centre-of-mass energy s=5.02TeV in the forward region is reported, using pp collision data collected by the LHCb experiment in year 2017, corresponding to an integrated luminosity of 100±2pb1.

Measurement of the CKM angle γ using the B±Dh± channels / LHCb Collaboration
A measurement of the CP-violating observables from B±DK± and B±Dπ± decays is presented, where D(D) is an admixture of D0 and D¯0 (D0 and D¯0) states and is reconstructed through the decay chains DDπ0/γ and DKS0π+π/KS0K+K. The measurement is performed by analysing the signal yield variation across the D decay phase space and is independent of any amplitude model. [...]

Prompt and nonprompt ψ(2S) production in pPb collisions at sNN=8.16 TeV / LHCb Collaboration
The production of ψ(2S) mesons in proton-lead collisions at a centre-of-mass energy per nucleon pair of sNN=8.16 TeV is studied with the LHCb detector using data corresponding to an integrated luminosity of 34 nb1. The prompt and nonprompt ψ(2S) production cross-sections and the ratio of the ψ(2S) to J/ψ cross-section are measured as a function of the meson transverse momentum and rapidity in the nucleon-nucleon centre-of-mass frame, together with forward-to-backward ratios and nuclear modification factors. [...]

Measurement of associated J/ψ-ψ(2S) production cross-section in pp collisions at s=13 TeV / LHCb Collaboration
The cross-section of associated J/ψ-ψ(2S) production in proton-proton collisions at a centre-of-mass energy of s=13 TeV is measured using a data sample corresponding to an integrated luminosity of 4.2 fb1, collected by the LHCb experiment. The measurement is performed for both J/ψ and ψ(2S) mesons having transverse momentum pT<14 GeV/c and rapidity 2.0<y<4.5, assuming negligible polarisation of the J/ψ and ψ(2S) mesons. [...]

The longitudinal polarization fraction of the D meson is measured in B0Dτ+ντ decays, where the τ lepton decays to three charged pions and a neutrino, using proton-proton collision data collected by the LHCb experiment at center-of-mass energies of 7, 8 and 13 TeV and corresponding to an integrated luminosity of 5 fb1. The D polarization fraction FLD is measured in two q2 regions, below and above 7 GeV2/c4, where q2 is defined as the squared invariant mass of the τντ system. [...]

The production of promptDs+ and D+ mesons is measured by the LHCb experiment in proton-lead (pPb) collisions in both the forward (1.5 < y < 4.0) and backward (-5.0 < y < -2.5) rapidity regions at a nucleon-nucleon center-of-mass energy of sNN=8.16 TeV. The nuclear modification factors of both Ds+ and D+ mesons are determined as a function of transverse momentum, pT, and rapidity. [...]

A search for CP violation in D0KS0K+π and D0KS0Kπ+ decays is reported. The search is performed using an unbinned model-independent method known as the energy test that probes local CP violation in the phase space of the decays. [...]
