摘要：We investigate the light-quark mass and spatial volume dependence of matrix elements of DB = 2 and DC = 2 four-fermion operators. These operators are relevant for B0 (s)−¯B0 (s) and D0−¯D0 mixing in and beyond the StandardModel. An important conclusion of this work is that the chiral extrapolations for matrix elements of heavy-light meson mixing beyond the Standard Model are more complicated than that for the Standard Model mixing matrix elements.
