Flavor Violations in $B$ -Mesons within Non-Minimal SU(5)

Bhubanjyoti Bhattacharya, Alakabha Datta, Gaber Faisel +2

Recent anomalies in $B$ -meson decays, such as deviations in $R_{D^{(*)}}$ and $B \to K I^½ I^ˉ ½$ , suggest possible lepton flavor universality violation and new exotic interactions.…

A joint explanation of the $B \to I ¨ K$ puzzle and the $B \to K I^½ I^ˉ ½$ excess

Wolfgang Altmannshofer, Shibasis Roy

In light of the recent branching fraction measurement of the $B^{+} \to K^{+} I^½ I^ˉ ½$ decay by Belle II and its poor agreement with the SM expectation, we analyze the effects of a…
