Summary of hints for new physics from (quark) flavour physics
Roman Zwicky
Recently two hints for new physics have emerged: The B_s mixing phase phi_s and the rate of D_s -> (mu,tau) nu exposing a discrepancy of \sim 3 sigma and 3.8 sigma deviation from t…
Unparticles and CP-violation
Roman Zwicky
We give a brief summary of the unparticle scenario proposed by Georgi. The CP-even phase of the propagator is exploited to study the CP-asymmetry in B+ --> tau+ + nu, which is neit…
Unparticles at heavy flavour scales: CP violating phenomena
Roman Zwicky
Coupling the scale invariant unparticle sector to flavour physics and assuming that it remains scale invariant we investigate its consequences in heavy flavour physics. A drastic f…
B->V gamma Beyond QCD Factorisation
Patricia Ball, Gareth W. Jones, Roman Zwicky
We calculate the main observables in and decays, i.e. branching ratios and CP and isospin asymmetries. We include QCD factorisation r…
