Scalar flavour-changing neutral currents in the large-tan(beta) limit
We analyse scalar flavour-changing neutral currents of down-type quarks in models with two Higgs doublets, coupled separately to up- and down-type quarks, in the limit where the ratio of the two expectation values ($\tan \beta = v_u/v_d$) is large. We clarify the origin of this phenomenon, both in $...
