Effects of Family Non-universal $Z^{\prime }$ Model in the angular observables of $B\to (\rho ,a_1){\mu }^{+}{\mu }^{-}$ decays

Nimra Farooq, Marwah Zaki, M. Ali Paracha +1

We present the angular distribution of the four-fold $B\to \rho (\to \pi \pi ){\mu }^{+}{\mu }^{-}$ and $B\to a_1(\to {\rho }_{\parallel ,\perp }\pi ){\mu }^{+}{\mu }^{-}$ decays both in the Standard Model and the family…
