Description
Clustering in systems with attractive forces are known in many physical settings:
for example in formation of globular clusters in Galaxies.
Formation of nuclear fragments is a well known phenomenon in low energy nuclear collisions,
especially at temperatures $T\sim 10\, MeV$ near the gas-liquid critical point.
At a freezeout stage of high energy collisions, with $T=100-150\, MeV$,
no clustering is generally expected. However, STAR measurement of the proton
number distribution has found that kurtosis (the 4-proton cumulant)
grows toward the lowest collision energies. Using some version of the mean field approximation and spherical geometry, we study whether the long-range forces, expected near the critical point, can generate bound multi-baryon ``globular clusters".
