Abstract
The latest LHC data confirmed the existence of a Higgslike particle and made interesting measurements on its decays into γγ ZZ W W τ + τ − and boverlineb It is expected that a decay into Zγ might be measured at the next LHC round for which there already exists an upper bound The Higgslike particle could be a mixture of scalar with a relatively large component of pseudoscalar We compute the decay of such a mixed state into Zγ and we study its properties in the context of the complex two Higgs doublet model analysing the effect of the current measurements on the four versions of this model We show that a measurement of the h → Zγ rate at a level consistent with the SM can be used to place interesting constraints on the pseudoscalar component We also comment on the issue of a wrong sign Yukawa coupling for the bottom in Type II modelsThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
