Exploration of SU(Nc) gauge theory with many Wilson fermions at strong coupling
Abstract
We explore aspects of the phase structure of SU(2) and SU(3) lattice gauge theories at strong coupling with many flavours Nf of Wilson fermions in the fundamental representation. The pseudoscalar meson mass as a function of hopping parameter is observed to deviate from the expected analytic dependence, at least for sufficiently large Nf. Implications of this effect are discussed, including the relevance to recent searches for an infrared fixed point.
