Heavy Ion Physics as seen from WUT

Some history1975- 1990

WUT at JINR - Dubna

M.I. Podgoretski

V.G. Grishin

1975 ~1990 - Grishin, propane bubble chamber group and others in Dubna - measured two-particle correlations for various reactions and two-particle systemsin the energy domain of several GeV/nucleon

Weekly meeting of propane bubble chamber group.

Catching up•Effective interaction time larger•Stronger correlation

Moving away•Effective Interaction time smaller•Weaker correlation

“Double” ratio•Sensitive to the space-time asymmetry in the emission process
