Polarisation fractions in $B\to V_1{V}_2$: U-Spin constraints and new physics signatures

Debajyoti Choudhury, Suman Kumbhakar, Anirban Kundu +1

We investigate the decays of $B$ mesons, {\em i.e.}, $B_d$, $B_s$, $B^{+}$, and their antiparticles, to two light vector mesons ($B\to V_1{V}_2$). We use the SU(2) U-spin symmetry, wh…
