Lr. Baboukhadia et al., LINEAR SIGMA-MODEL LINKAGE WITH NONPERTURBATIVE QCD, Journal of physics. G, Nuclear and particle physics, 23(9), 1997, pp. 1065-1075
Linkage is demonstrated between the quark mass, quark condensate and c
oupling strength in the infrared limit of QCD and in the quark-level l
inear sigma model.
