Constraining the heavy leptophilic neutral gauge bosons through the $Z\to {\ell }^{+}{\ell }^{-}$, $W^{\pm }\to {\ell }^{\pm }{\nu }_{\ell }$, and $h\to {\ell }^{+}{\ell }^{-}$ decays

Bibhabasu De, Amitabha Dey

We consider the hypothetical possibility of neutral gauge bosons ($Z^{\prime }$) with flavor-specific leptophilic couplings. For such New Physics (NP) interactions, the current experi…
