Baryon and lepton number in the standard model are violated by anomalies, even though the fermions are massive. This problem is studied in the context of a two dimensional model. In a uniform background field, fermion production arise from non-adiabatic behavior that compensates for the absence of massless modes. On the other hand, for localized instanton-like configurations, there is an adiaba...
Recently, a proposal for the full non-abelian open superstring effective action through O(α′3) has been formulated in hep-th/0108169. We test this result by calculating the spectrum in the presence of constant magnetic background fields and by comparing the result to string theoretic predictions. The agreement is perfect. Other proposals for the superstring effective action through this order d...
The positive potential energy required for inflation spontaneously breaks supersymmetry and in general gives any would-be inflaton an effective mass of order the inflationary Hubble parameter thus ruling it out as an inflaton. In this paper I give simple conditions on the superpotential that eliminate some potential sources for this mass, and derive a form for the Kähler potential that eliminat...
conclusions the diagnostics and management of infections with hepatotropic viruses, particularly hbv, are neglected in hemophilic patients. all patients with coagulation disorders and a history of exposure to non-inactivated blood products should be screened for blood-borne infections. the prevalence of other potentially blood-borne viral infections exhibited a pattern similar to that observed ...
Antibody to hepatitis A virus (anti-HAV) was found in 50% of patients with Indian childhood cirrhosis; this was not significantly different from the prevalence of anti-HAV in age- and sex-matched controls.
