Description

This talk will report on four measurement recently completed by ATLAS: (a) the decay of Lambda_b into Lambda and psi(2S), observed for the first time and compared to the decay into Lambda and J/psi; (b) the decay of Bc into J/psi Ds and J/psi Ds*, including the first polarisation measurement for the latter channel; (c) the measurement of the ratio of the fragmentation fraction f_s/f_d, which complements a previous measurement of LHCb over a different range of pT and y; (d) B+ mass reconstruction in the decay of B+ to J/psi and K+ at ATLAS at 13 TeV pp collisions; (e) Measurement of the differential non-prompt Jpsi production fraction at 13 TeV
