sHDECAY

The program sHDECAY is a modified version of the latest release of HDECAY 6.50.
It allows for the calculation of the partial decay widths and branching ratios of the
Higgs bosons in the real and in the complex singlet extensions of the Standard Model,
both in the broken and the dark matter phase of the models.
