概要	Recently, the standard model prediction of epsilon'/epsilon was improved, and a discrepancy from the experimental results was reported at the 2.9 sigma 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 the discrepancy can be explained if superparticles are lighter than 4-6TeV. Correlations with B(K-L ->pi(0) nu(nu) over bar) and other experimental constraints are also discussed. (C) 2016 The Author(s). Published by Elsevier B.V.
