Heavy and light quarks in the instanton vacuum
Assuming the gluon field is well approximated by instanton configurations we derive a light quarks determinant and calculate its contribution to the specific heavy quarks correlators – namely, the heavy quark propagator and heavy quark-aniquark correlator, receiving the instanton generated light-hea...
