How perturbative are heavy sea quarks?
Effects of heavy sea quarks on the low energy physics are described by an effective theory where the expansion parameter is the inverse quark mass, 1/M. At leading order in 1/M (and neglecting light quark masses) the dependence of any low energy quantity on the heavy quark mass is given in terms of...
