Angular Distributions of B -> K ll Decays
Christoph Bobeth, Gudrun Hiller, Giorgi Piranishvili
We model-independently analyze the angular distributions of B -> K ll decays, l = e, mu, for low dilepton mass using QCD factorization. Besides the decay rate, we study the forward…
Charged-Higgs Collider Signals with or without Flavor
Stefan Dittmaier, Gudrun Hiller, Tilman Plehn +1
A charged Higgs boson is a clear signal for an extended Higgs sector, as for example predicted by supersymmetry. Squark mixing can significantly change the pattern of charged-Higgs…
Photon polarization from helicity suppression in radiative decays of polarized Lambda_b to spin-3/2 baryons
G. Hiller, M. Knecht, F. Legger +1
We give a general parameterization of the Lambda_b --> Lambda(1520) gamma decay amplitude, applicable to any strange isosinglet spin-3/2 baryon, and calculate the branching fractio…
