Standard model and new physics for ϵ′ kϵk∞

Kitahara, Teppei

Abstract:
The first result of the lattice simulation and improved perturbative calculations have pointed to a discrepancy between data on ϵ′ k/ϵk and the standard-model (SM) prediction. Several new physics (NP) models can explain this discrepancy, and such NP models are likely to predict deviations of b(K → πvv) from the SM predictions, which can be probed precisely in the near future by NA62 and KOTO experiments. We present correlations between ϵ′ k/ϵk and B(K → πvv) in two types of NP scenarios: A box dominated scenario and a Z-penguin dominated one. It is shown that different correlations are predicted and the future precision measurements of K → πvv can distinguish both scenarios.
