How To Kill a Penguin
Ulrich Haisch
Within constrained minimal-flavor-violation the large destructive flavor-changing Z-penguin managed to survive eradication so far. We give a incisive description of how to kill it…
Recent Developments in Bbar -> X_s gamma
Ulrich Haisch
We present a concise review of the recent theoretical progress concerning the standard model calculation of the inclusive radiative Bbar -> X_s gamma decay. Particular attention is…
Determining the Sign of the Z-Penguin Amplitude
Ulrich Haisch, Andreas Weiler
We point out that the precision measurements of the pseudo observables R_b^0, A_b, and A_FB^0,b performed at LEP and SLC suggest that in models with minimal-flavor-violation the si…
Bound on minimal universal extra dimensions from Bbar -> X_s gamma
Ulrich Haisch, Andreas Weiler
We reexamine the constraints on universal extra dimensional models arising from the inclusive radiative Bbar -> X_s gamma decay. We take into account the leading order contribution…
Supersymmetric large tan(beta) corrections to DeltaM_(d,s) and B_(d,s) -> mu+mu- revisited
A. Freitas, E. Gasser, U. Haisch
We point out that in the minimal supersymmetric standard model terms from the mixing of Higgs and Goldstone bosons which are connected to the renormalization of tan(beta) via Slavn…
