Looking for CP violation in B -> tau+tau- decays
J. Kalinowski, P. H. Chankowski, Z. Was +1
In supersymmetry with large tan(beta) the decays B0(B0bar) -> l+l- are dominated by the scalar and pseudoscalar Higgs penguin diagrams leading to strong enhancement of leptonic dec…
Double protection of the Higgs potential
Zurab Berezhiani, Piotr H. Chankowski, Adam Falkowski +1
A mechanism of double protection of the Higgs potential, by supersymmetry and by a global symmetry, is investigated in a class of supersymmetric models with the SU(3)xSU(3)xU(1) ga…
Flavour Changing Neutral Currents and Inverted Sfermion Mass Hierarchy
P. H. Chankowski, K. Kowalska, S. Lavignac +1
We study the contraints on non-flavour-blind soft supersymmetry breaking terms coming from flavour and CP violating processes in the presence of hierarchical Yukawa couplings, and…
Flavour violation in general supergravity
Piotr H. Chankowski, Oleg Lebedev, Stefan Pokorski
We reappraise the flavour changing neutral currents (FCNC) problem in string--derived supergravity models. We overview and classify possible sources of flavour violation and find t…
