Charged scalar particles and {tau} leptonic decay

Abstract

Charged scalar particles introduced in some extensions of the standard model can induce {tau} leptonic at tree level. We find that with some charged SU(2)-singlet scalar particles, like ones introduced in Zee-type model, {tau} leptonic decay width is always smaller than what is predicted by the standard model, therefore they may offer a natural solution to {tau} decay puzzle. To be more specific, we examine some Zee-type models in detail to see if at the same time they are acceptable in particle physics, cosmology and astrophysics. It is shown that {tau} decay data do put some constraints on these models. (author). 25 refs, 1 fig.
