Query: Phase Diagram of An SU(2)xSU(2) Scalar-Fermion Model with Massless
  Decoupled Doublers   We present the phase structure of the chiral SU(2)xSU(2) scalar-fermion model
on the lattice using the Zaragoza proposal for chiral fermions. The numerical
result agrees with an analytic study based on the use of weak and strong Yukawa
coupling expansions combined with the mean field approach. The phase diagram
consits of four phases: paramagnetic(PM), ferromagnetic(FM),
antiferromagnetic(AFM) and ferrimagnetic (FI). The transition lines separating
these four phases intersect at one quadruple point.
