Scientific paper

Interest has increased recently in the possibility of a long-lived dihyperon (H particle) being the source of the signal from the Cygnus X-3 pulsar. It is shown here that, when the nonuniversality of the constant B which characterizes the external pressure of QCD vacuum on the quark bag is allowed for, the H particle turns out to be a short-lived particle, since it lies above the Lambda-Lambda threshold. The possible value of B for a six-quark system is estimated on the basis of data on the magnetic moment of the deuteron.
