MULTI - QUARK HADRONS : PRODUCTION OF S = - 2 SYSTEMS.

Description

The general character of 4-quark (mesonic) and strange 6-quark (baryonic) quark systems is very briefly reviewed a la Jaffe, i.e. in the MIT bag, and so far still possibly viable candidates are indicated. The concentration is on the latter (S = -2) systems, with some attention given to more likely to be discoverable light, doubly-strange nuclei. The two modes for generating doubly strange, generally double-{Lambda} nuclear systems, are considered and related to each other. Traditionally, one employs the (K{sup -},K{sup +}) reaction on a relatively light target and hopes to retain two units of strangeness on a single final state ... continued below

Description

The general character of 4-quark (mesonic) and strange 6-quark (baryonic) quark systems is very briefly reviewed a la Jaffe, i.e. in the MIT bag, and so far still possibly viable candidates are indicated. The concentration is on the latter (S = -2) systems, with some attention given to more likely to be discoverable light, doubly-strange nuclei. The two modes for generating doubly strange, generally double-{Lambda} nuclear systems, are considered and related to each other. Traditionally, one employs the (K{sup -},K{sup +}) reaction on a relatively light target and hopes to retain two units of strangeness on a single final state fragment. Alternatively, heavy ion reactions can be used to produce {Lambda}-hyperons copiously and one seeks to observe coalescence of two of these particles into the lightest S=-2 nucleus, the H-dibaryon. The complications arising from the presence of a repulsive core in the baryon-baryon interaction on the production of the H are discussed. Also considered is the possible presence in the data from the AGS experiment E906, of slightly heavier S=-2 nuclei, in particular in the system {sub {lambda}{lambda}}{sup 4}H.
