BK and explicit chiral symmetry breaking

Bijnens, Johan LU orcid and Prades, Joaquim (1995) In Physics Letters B 342(1-4). p.331-338
Abstract

The BK parameter is discussed in the general context of calculating beyond the factorization approximation for hadronic matrix elements. A variant of the 1 Nc method of Bardeen et al. is used. We present calculations within a low energy approach and a calculation within the Nambu-Jona-Lasinio model. Matching with the QCD behaviour and dependence on non-zero current quark masses is studied.
