Description

The long standing deviation of the measured value of ${ϵ}^{\prime }/ϵ$ from the Standard Model prediction calls for a rigorous analysis of effects beyond the Standard Model (BSM) to $K\to \pi \pi$ decays. In this talk I will present results of scalar-scalar and tensor-tensor matrix elements relevant for ${ϵ}^{\prime }/ϵ$, which have been obtained for the first time recently, using the Dual QCD approach. Furthermore I will present a master formula which allows to compute the value of ${ϵ}^{\prime }/ϵ$ in any given BSM scenario.
