Renormalization Group Scaling of Higgs Operators and \Gamma(h -> \gamma \gamma) [PDF]
, 2013 We compute the renormalization of dimension six Higgs-gauge boson operators that can modify \Gamma(h -> \gamma \gamma) at tree-level. Operator mixing is shown to lead to an important modification of new physics effects which has been neglected in past ...
