Hadronic vs leptonic flavor and CP violation in SUSY SO(10)
Sebastian Jager, Ulrich Nierste
We study hadronic and leptonic flavor physics in a SUSY SO(10) model proposed by Chang, Masiero, and Murayama, which links b -> s transitions to the observed large atmospheric neut…
CP asymmetry in flavour-specific B decays
Ulrich Nierste
I first discuss the phenomenology of a^q_fs (q=d,s), which is the CP asymmetry in flavour-specific B_q decays such as B_d -> X l^+ nu-bar_l or B_s -> D_s^- pi^+. a^q_fs can be obta…
Supersymmetric corrections to Higgs decays and b-> s gamma for large tan beta
U. Nierste
If tan beta is large, supersymmetric QCD corrections can become large, putting naive perturbation theory into doubt. I show how these tan-beta-enhanced corrections can be controlle…
The width difference of B_s mesons
Ulrich Nierste
Next-to-leading order QCD corrections to the width difference Delta Gamma in the B_s-meson system are presented. I further discuss how Delta Gamma can be used to detect new physics…
QCD corrections to lifetime differences of B_s mesons
Ulrich Nierste
The calculation of QCD corrections to the width difference Delta Gamma in the B_s meson system is presented. The next-to-leading order corrections reduce the dependence on the reno…
Inclusive direct CP-asymmetries in charmless B^{+/-}-decays
U. Nierste
Direct CP-asymmetries in inclusive decay modes can be cleanly calculated by exploiting quark-hadron duality. This is in sharp contrast to CP-asymmetries in exclusive channels, wher…
