Baryon junction loops and the baryon-meson anomaly at high energies

A new version, v2.0, of the $\mathrm{HIJING}∕B\overline{B}$ Monte Carlo nuclear collision event generator is introduced in order to explore further the possible role of baryon junctions loops in the baryon-meson anomaly $(2<p_T<5\mathrm{GeV}∕c)$ observed in $200A\mathrm{GeV}$ $\mathrm{Au}+\mathrm{Au}$ reactions at RHIC. We show that junction loops with an enhanced intrinsic $k_T\approx 1\mathrm{GeV}∕c$ transverse momentum kick may provide a partial explanation of the anomaly as well as other important baryon stopping observables.
