[[BR]] 22 Importantly, field rotations required to have canonically normalized kinetic terms and parameter redefinitions following from the choice of an input parameters set are automatically applied in the Lagrangian. 21 The SM Lagrangian [link] is included and extended with the SM loopinduced Higgs couplings to gg, γγ and Zγ.

Each set contains a main file, a number of subroutines and restriction files. … … 39 40 40 41 41 We appreciate if you could reportus any inconsistency or bugs.42 We would appreciate if you could report to us any inconsistency or bugs. 42 43 43 44
