Baryon production in a topological model

Abstract

We develop and make predictions using a topological model for baryon production that we proposed in a previous paper. “Cool” partons close to mass shell are argued to be in one-to-one correspondence with independent domains which break chiral symmetry spontaneously by non-perturbatively developing randomly-oriented chiral condensates. Baryons are formed where there are topological mismatches between the chiral orientations in adjacent domains. We give an algorithm based on the random lattice approach to field theory for calculating the spatial locations of different domains and defining when they are adjacent. We show that the mean baryon multiplicity should grow faster than the number of “cool” partons, which explains the observed increase of baryon production in Ψ decays, predicts a rapid increase in baryon production at LEP, implies that baryons should not have a Poisson multiplicity distribution, and means that events with baryons should have a higher mean sphericity. A further ansatz yields a baryon energy distribution that agrees very well with TPC data.
