MONTE CARLO STUDY OF SU(2)×SU(2) CHIRAL MODEL WITH MIXED ACTION ON THE 2-DIMENSIONAL RANDOM LATTICE

摘要

We analyzed the SU(2)×SU(2)chiral model with mixed fundamental-adjoint action on the 2-dimensional(2-D)random lattice by using Monte-Carlo(M-C)simulation.The results sluw that the model behaves like the mixed SU(2)×SU(2)chiral model on the 2-D regular lattice,but the character of the phase transition seems to be different.
