چکیده

We study strange dibaryons based on the SU(2)-embedded B = 2 toroidal soliton. Treating the excursions of the soliton into strange directions as small rigid oscillations, we obtain a good approximation to the bound state approach. We calculate the dibaryon mass formula to order 1/N and find that the doubly strange I = J = 0 dibaryon is bound by about 90MeV.

Strange Dibaryons in the Simplified Skyrme Model

Abstract : We show that the bound-state approach to the strange dibaryons in the Skyrme model can be considerably simplified by omitting the Skyrme stabilizing term proportional to e-2 and using the regularized version of the quantum stabilization proposed by Mignaco and Wulck . The strange dibaryons are obtained assystems consisting ofbound antikaons in a (variational) axially symmetric SU(2)-...

Simple description of strange dibaryons in the Skyrme model.

The existence of stable multibaryon states with vanishing hypercharge, although not yet experimentally confirmed, remains an exciting possibility. The simplest of such states, the doubly strange dibaryon H , was first conjectured to exist in @1#. On the basis of an MIT bag model calculation, its mass was predicted to be mH52150 MeV, well below the LL threshold. This means that all strong decays...

From Skyrmions to NN phase shifts.

We study the NN phaseshifts in a Hamiltonian obtained from quantization of the collective modes in the Skyrme model. We show that a combination of an adiabatic and diabatic approximation gives a good NN force, with sufficient attraction to produce a bound deuteron. The description of the repulsive core appears to be the main cause for the remaining discrepancies between the Skyrme model force a...

Strange Dibaryons in Neutron Stars and in Heavy-Ion Collisions

The formation of dibaryons with strangeness are discussed for the interior of neutron stars and for central relativistic heavy-ion collisions. We derive limits for the properties of H-dibaryons from pulsar data. Signals for the formation of possible bound states with hyperons at BNL’s Relativistic Heavy-Ion Collider (RHIC) are investigated by studying their weak decay patterns and production ra...
