Abstract We present eHDECAY, a modified version of the program HDECAY which includes the full list of leading bosonic operators of the Higgs effective Lagrangian with a linear or non-linear realization of the electroweak symmetry and implements two benchmark composite Higgs models. Title of program: eHDECAY Catalogue Id: AEUJ_v1_0 Nature of problem Numerical calculation of the decay widths and branching ratios of a Higgs like boson within four different parametrisations: the non-linear Lagrangian, the Strongly-Interacting Light Higgs (SILH) Lagrangian and the MCHM4 and MCHM5 Lagrangians. The Fortran program eHDECAY includes the most important higher-order QCD effects and in case of the SILH and composite Higgs parametrisation also the electroweak (EW) higher order corrections. The user furthermore has the possibility to turn off these EW c ...
