Abstract:We calculate BSM hadronic matrix elements for K 0-K 0 mixing in the Dual QCD approach (DQCD). The ETM, SWME and RBC-UKQCD lattice collaborations find the matrix elements of the BSM density-density operators O i with i = 2-5 to be rather different from their vacuum insertion values (VIA) with B 2 ≈ 0.5, B 3 ≈ B 5 ≈ 0.7 and B 4 ≈ 0.9 at µ = 3 GeV to be compared with B i = 1 in the VIA. We demonstrate that this pattern can be reconstructed within the DQCD through the nonperturbative meson evolution from very low … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
