Effects of Family Nonuniversal Z' Boson on Leptonic Decays of Higgs and Weak Bosons

Understand

Though not completely a surprise according to the standard model and existing indirect constraints, the Higgs-like particle, h, of mass around 125 GeV recently observed at the LHC may offer an additional window to physics beyond the standard model.

• In particular, its decay pattern can be modified by the existence of new particles.
• One of the popular scenarios involves a Z' boson associated with an extra Abelian gauge group.
• In this study, we explore the potential effects of such a boson with family-nonuniversal couplings on the leptonic decays of h, both flavor-conserving and flavor-changing.
