An upper bound on the Kaon B-parameter and Re(epsilon_K)

TL;DR

This paper revisits the weak K^0-ar{K}^0 transition using a large-N_c approach, providing an upper bound on _B_K and the Kaon indirect CP violation based on recent B physics data and theoretical insights.

Contribution

It introduces a large-N_c framework to establish an upper limit on _B_K and Kaon CP violation, integrating new B physics data with theoretical developments.

Findings

Derived an upper bound on _B_K.

Provided constraints on Kaon indirect CP violation.

Linked B physics data with K physics theoretical models.

Abstract

New precise data in B physics and theoretical developments in K physics lead us to reconsider the weak K^0-\bar{K}^0 transition from a large-N_c viewpoint, N_c being the number of colors. In this framework, we infer an upper limit on \hat{B}_K and the Kaon indirect CP violation.
