The baryon-baryon continuum invariant mass spectrum generated fromrelativistic nucleus + nucleus collision data may reveal the existence ofdoubly-strange dibaryons not stable against strong decay if they lie within afew MeV of threshold. Furthermore, since the dominant component of these statesis a superposition of two color-octet clusters which can be producedintermediately in a color-deconfined quark-gluon plasma (QGP), an enhancedproduction of dibaryon resonances could be a signal of QGP formation. A totalof eight, doubly-strange dibaryon states are considered for experimental searchusing the STAR detector (Solenoidal Tracker at RHIC) at the new RelativisticHeavy Ion Collider (RHIC). These states may decay to Lambda-Lambda and/orproton-Cascade-minus, depending on the resonance energy. STAR's largeacceptance, precision tracking and vertex reconstruction capabilities, andlarge data volume capacity, make it an ideal instrument to use for such asearch. Detector performance and analysis sensitivity are studied as a functionof resonance production rate and width for one particular dibaryon which candirectly strong decay to proton-Cascade-minus but not Lambda-Lambda. Resultsindicate that such resonances may be discovered using STAR if the resonanceproduction rates are comparable to coalescence model predictions for dibaryonbound states.Comment: 28 pages, 5 figures, revised versio

Can doubly strange dibaryon resonances be discovered at RHIC?
