Sherry Towers (Ottawa-Carleton Institute for Physics)
TL;DR
This paper derives limits on the charged Higgs mass in type II Higgs doublet models using current measurements of charged kaon and tau to kaon decay rates, constraining new physics parameters.
Contribution
It provides the first combined constraint on charged Higgs parameters from both kaon and tau decay data within the MSSM framework.
Findings
$ an{eta}/m_H < 0.21$ GeV$^{-1}$ at 90% confidence level
Sets new bounds on charged Higgs properties in supersymmetric models
Utilizes current world average branching fractions for analysis.
Abstract
From an analysis of the current world averages of the charged kaon and tau to kaon branching fractions, we derive, within the framework of type II Higgs doublets models such as the Minimal Supersymmetric Extension of the Standard Model, GeV at a 90% confidence limit.
