The branching fraction of B s 0 → K 0 K ¯ 0 $$ {B}_s^0\to {K}^0{\overline{K}}^0 $$ : three puzzles

Abstract The branching fraction of the B s → K 0 K ¯ 0 $$ {B}_s\to {K}^0{\overline{K}}^0 $$ decay has been recently measured by the LHCb and Belle experiments. We study the consistency of the measured value with three relations to other decay rates and CP asymmetries which follow from the Standard M...
