Anomalies For Pedestrians, Br Holstein Dec 1992

Anomalies For Pedestrians, Br Holstein

Barry R Holstein

The subject of anomalies, i.e., quantum mechanical symmetry breaking, is addressed using only basic quantum mechanics. Examples from different areas of physics are examined

Solvable Quantum Mechanical Examples Of Broken Supersymmetry, Asim Gangopadhyaya Dec 1992

Solvable Quantum Mechanical Examples Of Broken Supersymmetry, Asim Gangopadhyaya

Asim Gangopadhyaya

We construct several analytically solvable examples of broken supersymmetry in non-relativistic quantum mechanics. Our examples are motivated from known shape-invariant potentials obeying unbroken supersymmetry and are obtained from them via suitable mapping procedures.

Chiral Invariance And Electroweak Interactions Of Pions And Kaons, Br Holstein Dec 1991

Chiral Invariance And Electroweak Interactions Of Pions And Kaons, Br Holstein

Barry R Holstein

Electroweak interactions of pions and kaons are studied in the context of chiral perturbation theory. We demonstrate that the effective Lagrangian framework allows a consistent and predictive picture of such processes as well as a succinct way in which to represent the many previous studies of these reactions which have been performed using chiral models.


Reconstruction And Future Trends Of The Aids Epidemic In The United States, Ron Brookmeyer Nov 1991

Reconstruction And Future Trends Of The Aids Epidemic In The United States, Ron Brookmeyer

Ron Brookmeyer

There has been considerable uncertainty in estimates of past and current human immunodeficiency virus (HIV) infection rates in the United States. Statistical estimates of historical infection rates can be obtained from acquired immunodeficiency syndrome (AIDS) incidence data and the incubation period. However, this approach is subject to a number of sources of uncertainty and two other approaches, epidemic models of HIV transmission and surveys of HIV prevalence, are used to corroborate and refine the statistical estimates. Analyses suggest the HIV infection rate in the United States grew rapidly in the early 1980s, peaked in the mid-1980s, and subsequently declined markedly. …
