This study investigates the excesses observed in the CMS diphoton and ditau data around within the framework of the flavor-dependent
model. The model introduces a singlet scalar to explain the nonzero neutrino masses. This newly introduced Higgs interacts directly with the quark sector, motivated by the aim to explain the flavor numbers of the fermion sector. Additionally, it undergoes mixing with the SM-like Higgs boson. The study suggests that designating this singlet Higgs state in this model as the lightest Higgs boson holds great potential for explaining the excesses around
In the calculations, we maintained the masses of the lightest and next-to-lightest Higgs bosons at around
and
respectively. It was found that the theoretical predictions on the signal strengthes
in the flavor-dependent
model can be fitted well to the excesses observed at CMS.
