The 2010 data on quark flavour physics reveal a considerable tension
with the Standard Model. However, an excellent fit is found if one
permits new physics in the amplitudes describing meson-antimeson mixing
in the B_d and B_s systems. The corresponding global analysis disfavours
the Standard Model at the level of 3.6 standard deviations and calls for
new sources of CP violation in the...

Polarisation observables in top quark decays are sensitive probes of possible new physics contributions to the interactions of the heavy third generation quarks. Within an effective theory approach such new physics contributions can be classified in terms of several higher dimensional operators. We investigate the interplay between indirect constraints on such operators, coming mainly from...

I discuss the anomalously large asymmetry in top-antitop-quark production within Randall-Sundrum models. Kaluza-Klein gluons generically have the potential to generate a large forward-backward asymmetry at tree level. In models with an anarchic flavour structure, however, their coupling to the light quarks inside the proton is strongly suppressed. I show that even though this suppression is...

We present recent results on rare B and D decays from the Babar experiment. The focus will be on measurements that are sensitive to the presence of New Physics. Several flavour-changing-neutral-current channels have been investigated: we present results on the CP asymmetry in b -> s gamma, searches for B -> K nu nubar, B -> K tau tau and B0/D0 -> gamma gamma, as well as the branching fraction...

The QCD production of Quarkonia and high-PT B-hadrons are important processes as a probe of perturbative QCD. High-PT B-hadrons also form a significant background to many new physics channels at the LHC.
The inclusive production of the J/psi and Upsilon mesons is studied in the dimuon decay mode. The double- differential cross section is measured with respect to the transverse momentum and...
