Available in PDF, EPUB and Kindle. Book excerpt: In this study, the decays B+c → J/?D+s and B+c → J/? D*+s are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 and 20.6 fb–1 of pp collisions collected at centre-of-mass energies √s=7 TeV and 8 TeV, respectively. Signal candidates are identified through J/? → ?+?– and D(*)+s → ??+(?/?0) decays. With a two-dimensional likelihood fit involving the B+c reconstructed invariant mass and an angle between the ?+ and D+s candidate momenta in the muon pair rest frame, the yields of B+c → J/?D+s and B+c → J/? D*+s, and the transverse polarisation fraction in B+c → J/? D*+s decay are measured.
