Hdibaryon production in nuclear collisions

摘要

We discuss the production of the doubly strange H dibaryon in heavy ion collisions at high energy. In a hadron gas, we estimate the H formaiton rate, relative to LAMBDA LAMBDA quasifree production, to be order 10~-3, based on a conventional coalescence model. If the quark-gluon plasma phase is excited, we expect enhancement relative to the hadronic rate. We explore various schemes for detecting the H in the high multipplicity background characteristic of heavy ion collisions.
