Chargino contributions in light of recent ϵ′/ϵ
Recently, the standard model prediction of ϵ′/ϵ was improved, and a discrepancy from the experimental results was reported at the 2.9σ level. We study the chargino contributions to Z penguin especially with the vacuum stability constraint. The vacuum decay rate is investigated, and it is shown that...
