Measurement of Ξ+c production in pPb collisions at sNN=8.16 TeV at LHCb / LHCb Collaboration

Test of lepton flavour universality using B0Dτ+ντ decays with hadronic τ channels / LHCb Collaboration
The branching fraction B(B0Dτ+ντ) is measured relative to that of the normalisation mode B0Dπ+ππ+ using hadronic τ+π+ππ+(π0)ˉντ decays in proton-proton collision data at a centre-of-mass energy of 13 TeV collected by the LHCb experiment, corresponding to an integrated luminosity of 2 fb1. The measured ratio is B(B0Dτ+ντ)/B(B0Dπ+ππ+)=1.79±0.11±0.11, where the first uncertainty is statistical and the second is related to systematic effects. [...]
