Description
Within the 2HDM, it is usual to impose a $Z2$ symmetry to avoid the presence of flavor-changing neutral currents in the model at the tree level. This symmetry can be softly broken by a term in the Lagrangian proportional to a new parameter $m_{12}$. This parameter introduces a new energy scale in the model and is only present in the scalar interactions of the 2HDM. We explore the possible sensitivity to this parameter $m_{12}$ from the di-photon decay of the SM-like Higgs boson. We conclude that, with the present data, this decay can set additional bounds on $m_{12}$ at the 95% CL while respecting the rest of the relevant constraints of the model. Furthermore, we also show that the new measurement of the $W$ boson mass has a lesser impact on the derived limits.
