STRANGE PARTICLE ENHANCEMENT IN ULTRARELATIVISTIC NUCLEUS-NUCLEUS SCATTERING

We demonstrate that a proper treatment of double-colour exchange in th e string model VENUS leads to double strings. Such strings correspond to a (say) forward moving quark being linked via two ordinary strings to two backward moving quarks. Leading baryons now require the breakin g of two strings. Having twice the chance of producing a strange qqBAR pair, these strings produce twice as many strange baryons as compared to ordinary strings, therefore leading to an enhancement of strange b aryons in AA relative to pp collisions.
