Multi-strange-quark states at ultra-relativistic heavy-ion collisions

We examine the possibility of producing and evidencing exotic strange matter (strangelets and metastable multi-hypernuclear objects, MEMO's), including also pure hyperonic bounds states ((LambdaLambda) //b, (XiLambda)//b), at RHIC and LHC. Simulations are presented to estimate the sensitivity of the STAR and ALICE experiments to the detection of these objects, focusing mainly on metastable short-lived (weak decaying) strange dibaryons, with a particular emphasis on the H-dibaryon, a six quark-bag bound state (uuddss). 6 Refs.
