Study of the rare decays $B_{(}s,d{)}^{\ast }$ arrow $l^{+}{l}^{-}$ in Z' model

Debika Banerjee, Priya Maji, Sukadev Sahoo

The rare decays $B_{(s,d)}^{\ast }\to l^{+}{l}^{-}$ are important to probe the flavour sector of the standard model and to search new physics beyond the SM. Unlike pseudoscalar B meson, the l…
