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

We analyzed the SU(2)x 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 show that the model behaves like the mixed SU(2)xSU(2) chiral model on the 2–D regular lattice, but the character of the phase transition seems to be different.
