## [High energy particle physics at Purdue, 1989--1990]. Progress report, January 1989--May 1990

The theoretical and experimental high energy physics program is reviewed, including developments on particle detectors. Among the topics addressed are the following: the CLEO experiment; gamma ray astrophysics; highest-weight representations of affine Kac-Moody algebras; supersymmetric field theories; parity- violating effects and superconductivity in 2 + 1 dimensional supersymmetric QED; neutrino oscillations with applications to solar and supernova neutrinos; a search for the quark-gluon plasma using the Fermilab collider; the Solenoid Detector Collaboration at SSC; the high-resolution vertex chamber at TRISTAN; CP violation in e{sup +}e{sup {minus}}{yields}{phi}{yields}K{sub L}K{sub S}; deviations from Coulomb`s Law; and the electric charge and equations of statemore »
