"Neutron electric dipole moment from flavor changing Higgs couplings"

Wednesday, 9th of November, 11:00h, F-201

We consider neutron electric dipole moment contributions induced by
flavour changing Higgs boson couplings to quarks. Previously one loop
diagrams with such couplings were considered in order to constrain
such couplings. In the present paper the analysis is extended to the
two loop level, where the large SM Yukawa coupling for Higgs to top
as well as the large SM Higgs coupling to the  W-boson compensates
for the loop suppression factor.

Unfortunately, some of the contributing diagrams have logarithmically
divergent subloops, and  this theory is not renormalizable.
The logarithmically divergent terms are parametrized in terms of a
cut-off of order 1 to 3 TeV. Given the experimental bound of the
neutron electric dipole moment, we obtain a bound on the flavor changing
Higgs coupling of same order of  magnitude as the one reported by other
authors from $B$--$\bar{B}$-mixing.


Best regards,

Ivica Smolić
