    “…The second part of the dissertation is a research on the B-meson lifetimes at LHCb. The lifetimes au_{B+} and au_{B0} of B+ and B0 mesons are extracted in a simulation study, using the B+ -> J/psi K+ and B0 -& gt; J/]psi K* decay modes. …”

    “…The covariance properties of angular momentum eigenstates imply the existence of a rotation-invariant relation among the parameters of the di-fermion decay distribution of inclusively observed vector mesons. This relation is a generalization of the Lam-Tung identity, a result specic to Drell-Yan production in perturbative QCD, here shown to be equivalent to the dynamical condition that the dilepton is always produced transversely polarized with respect to quantization axes belonging to the production plane.…”

    “…As part of the UKQCD and RBC collaborations' N_f=2+1 domain-wall fermion phenomenology programme, we calculate the first two moments of the light-cone distribution amplitudes of the pseudoscalar mesons pion and kaon and the (longitudinally-polarised) vector mesons rho, K-star and phi. …”

    “…A new determination of the Q/sub A/-Q/sub B/ mixing angle and of the antisymmetric coupling for the vector-pseudoscalar decay of the axial vector mesons is presented. This uses information from the decay rates of the A/sub 1/ and C mesons found in the study of baryon exchange processes in K/sup -/p interactions at 4.2 GeV/c combined with the decay rate B to omega pi . …”
