1110.1942 (A. S. Cornell et al.)

Scaling of the CKM Matrix in the 5D MSSM    [PDF]

A. S. Cornell, Aldo Deandrea, Lu-Xin Liu, Ahmad Tarhini
We discuss a five-dimensional Minimal Supersymmetric Standard Model
compactified on a $S^1/Z_2$ orbifold, looking at, in particular, the one-loop
evolution equations of the Yukawa couplings for the quark sector and various
flavor observables. Different possibilities for the matter fields are
discussed, that is, where they are in the bulk or localised to the brane. The
two possibilities give rise to quite different behaviours. By studying the
implications of the evolution with the renormalisation group of the Yukawa
couplings and of the flavor observables we find that, for a theory that is
valid up to the unification scale, the case where fields are localised to the
brane, with a large $\tan\beta$, would be more easily distinguishable from
other scenarios.
