abstract = "We demonstrate that previous estimates of baryosynthesis levels in supergravity models designed to produce completely acceptable cosmological scenarios have been incorrect. With baryosynthesis with light Higgs, produced after primordial inflation with a mass ∼ 1010 GeV, we find nB/nγ {less-than or approximate} 10-5 ε{lunate}, where ε{lunate} is the baryon number asymmetry per decay.",

note = "Funding Information: With the realization that inflationary cosmologies [ 1] may allow a derivation of the primordial fluctuation spectrum responsible for galaxy formation [2,3] several efforts have focused on models which might produce an acceptable spectrum [4,5]. Supersymmetric potentials can more easily be made flat enough to suppress initial fluctuations in the scalar field responsible for inflation ,1, and as a result, there has been some interest in determining whether a cosmological scenario involving supersymmetry is acceptable. One such scenario, incorporating supergravity, and designed specifically in an attempt to avoid the pitfalls associated with present more tightly constrained models, has been called primordial inflation [7]. The nomenclature is due to the fact that the scalar field responsible for inflation gets a vacuum expectation value of order of the Planck mass, the {"}primordial{"} scale in the model. Acceptable cosmological behavior is in principle derived by incorporating some non-renormalizable terms in the superpotential for this scalar field, but only those that do not produce cosmological difficulties. Non-renormalization theorems [8] in principle imply that these dangerous terms, if not present initially, are not induced. While one may qtjestion the naturalness and fine tuning in such a model, it is worthwhile examining ¢' Research supported in part by the National Science Foun-dation under Grant No. PHY-82-.5249 and by NSERC. 1 Junior FeUow, Harvard Society of Fellows. .1 See, for example, reference [3] and references contained therein, and ref.
