star physics results: HBT and interferometry

The HBT puzzle

Hanbury-Brown Twiss (HBT) interferometry of two-pion correlations allows one to study the source size at thermal freeze-out, the point at which particles no longer interact. Predictions of long-lived systems, associated with quark-gluon plasma formation, led to predictions of much larger system sizes at RHIC. More...
