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.
