Suppression of the repulsive force in nuclear interactions near the
chiral phase transition    [PDF]

Chihiro Sasaki

We introduce an effective chiral Lagrangian with a dilaton responsible for
the trace anomaly in QCD. As the "dilaton limit" is taken, which drives a
system to near chiral restoration density, a linear sigma model emerges from
the highly non-linear structure. A striking prediction is that the
vector-meson--nucleon interaction gets strongly suppressed when the dilaton
limit is approached. Its phenomenological implications for the thermodynamics
of dense baryonic matter are briefly discussed.
