Abstract:
We investigate the effect of a charged Higgs boson (H±) on the
decays D±s →µ±νµ and
D±s →τ±ντ, which will be measured with high
precision at forthcoming CLEO-c.
We emphasize that such contributions should
not be overlooked when comparing lattice calculations
of fDs to the values obtained from these decays.
