Zhang Yanbin Nanjing University 2008.03 Quark mass dependence of the lattice gluon propagator in the infared region Zhang Yanbin Nanjing University 2008.03

Introduction The lattice gluon propagator Configurations Numerical results Conclusions

Conclusions Finite and enhancement in infrared region. 5~10% for the two flavors case and 30% for the three flavors case depressed than the quenched. Independent on the small quark mass, both the two and three flavors cases. But when the quark mass increases further, the results tend to be the behavior of quenched one.
