Ln and H ! S0n. Our search has yielded two candidate events from which we set an upper limit on the H production cross section. Normalizing to the inclusive L production cross section, we find sdsH ydVdysdsLydVd , 6.3 3 1026 at 90% C.L., for an H of mass ø2.15 GeVyc2. [S0031-9007(96)00050-6]

H-Dibaryon Results from KTeV
Results from the KTeV experiment at Fermilab using Ξ hyperons are presented, especially the first form-factor (FF) measurement from its semi-leptonic decay. This decay, which is an important test of the Standard Model, was observed for the first time using the 1997 KTeV experiment. We also report on the analysis of a large samples of Ξ weak radiative decays, and a search for the decay of a ligh...
متن کاملSearch for the weak decay of a lightly bound H0 dibaryon
We present results of a search for a new form of hadronic matter, a six-quark, dibaryon state called the H0, a state predicted to exist in several theoretical models. Analyzing data collected by experiment E799-II at Fermilab, we searched for the decay H0-->Lambdappi(-) and found no candidate events. We place an upper limit on [B(H0-->Lambdappi(-))dsigma(H)/dOmega]/(dsigma(Xi)/dOmega) and, in t...
متن کاملStatus of baryonic B decays
An overview of exclusive two-body and three-body baryonic B decays is given. The threshold enhancement effect in the dibaryon invariant mass and the angular distributions in the dibaryon rest frame are stressed and explained. Weak radiative baryonic B decays mediated by the electromagnetic penguin process b → sγ are discussed. Apart from the first observation of the radiative penguin decay B− →...
متن کاملDibaryons with strangeness: their weak nonleptonic decay using SU(3) symmetry and how to find them in relativistic heavy-Ion collisions
Weak SU(3) symmetry is successfully applied to the weak hadronic decay amplitudes of octet hyperons. Weak nonmesonic and mesonic decays of various dibaryons with strangeness, their dominant decay modes, and lifetimes are calculated. Production estimates for the Brookhaven Relativistic Heavy Ion Collider are presented employing wave-function coalescence. Signals for detecting strange dibaryon st...
متن کاملCan Doubly Strange Dibaryon Resonances be Discovered at RHIC?
The baryon-baryon continuum invariant mass spectrum generated from ultrarelativistic nucleus + nucleus collision data may reveal the existence of doubly-strange dibaryons not stable against strong decay if they lie within a few MeV of threshold. Furthermore, since the dominant component of these states is a superposition of two color-octet clusters which can be produced intermediately in a colo...
