CP Violation in τ Decays at SuperB & Belle II Experiments – like Finding Signs of Dark Matter

BaBar has found ACP(τ−→νKSπ−[≥π0])=(−0.36±0.23±0.11)% with 2.8 σ difference with SM prediction ACP(τ−→νKSπ−)=(0.36±0.01)% based on oscillation. Four central points: (i) to establish both the ‘existence’ of New Dynamics (ND) and its ‘features’ in local CP asymmetries; (ii) to increase the number of final states to be probed; (iii) to emphasize correlations of CP violations between different final states; (iv) likewise for the correlations with D± final states. These measurements should be possible at SuperB & Belle II experiments.
