  There is a growing evidence for the anomalously large semileptonic CP
asymmetry in the B meson system measured at the Tevatron. The noncontractible
space, as an alternative symmetry-breaking mechanism to the Higgs mechanism,
can change standard field theoretic calculations of the physical processes
mediated through quantum loops for large external momenta or large internal
masses. The presence of the W bosons and t-quarks in loops of the B meson
mixing can enhance the corresponding semileptonic CP asymmetry when the loop
integration is up to the universal Lorentz and gauge invariant UV cut-off. We
show that the enhancement is roughly 13%, thus the possible deviation is
measurable at the Tevatron, LHCb, SuperKEKB and SuperB facilities.
