Query: Nucleon Properties at Finite Temperature in the Extended Quark-Sigma
  Model   Hadron properties are studied at hot medium using the quark sigma model. The
quark sigma model is extended to include eighth-order of mesonic interactions
based on some aspects of quantum chromodynamic (QCD) theory. The extended
effective potential tends to the original effective potential when the coupling
between the higher order mesonic interactions equal to zero. The field
equations have been solved in the mean-field approximation by using the
extended iteration method. We found that the nucleon mass increases with
increasing temperature and the magnetic moments of proton and neutron increase
with increasing temperature. A comparison is presented with recent previous
works and other models. We conclude that higher-order mesonic interactions play
an important role in changing the behavior of nucleon properties at finite
temperature. In addition, the deconfinement phase transition is satisfied in
the present model.
