Abstract:

We examine the decays

t\rightarrow c\gamma

and

c Z~0

in two-Higgs doublet models where there is no discrete symmetry preventing tree-level flavour changing neutral currents. Flavour changing couplings of neutral Higgs scalars are assumed to be proportional to fermion masses, evading bounds on FCNC's from the light quark sector. These rare top decays may be visible at the SSC.

neutral current: flavor changing
top
top: rare decay
rare decay: quark
Higgs particle: doublet
Higgs particle: mass
mass: Higgs particle
coupling: Yukawa
Yukawa: coupling
top: branching ratio
