Research program in theoretical high energy physics
Abstract
This year's research has dealt with: superstrings in the early universe; the invisible axion emissions from SN1987A; quartic interaction in Witten's superstring field theory; Wboson associated multiplicity and the dual parton model; cosmic strings and galaxy formation; cosmic strings and baryogenesis; quark flavor mixing; p p() scattering at TeV energies; random surfaces; ordered exponentials and differential equations; initial value and backreaction problems in quantum field theory; string field theory and Weyl invariance; the renormalization group and string field theory; the evolution of scalar fields in an inflationary universe, with and without the effects of gravitational perturbations; cosmic string catalysis of skyrmion decay; inflation and cosmic strings from dynamical symmetry breaking; the physic of flavor mixing; stringinspired cosmology; strings at highenergy densities and complex temperatures; the problem of nonlocality in string theory; string statistical mechanics; largescale structures with cosmic strings and neutrinos; the delta expansion for stochastic quantization; highenergy neutrino flux from ordinary cosmic strings; a physical picture of loop bremsstrahlung; cylindricallysymmetric solutions of fourdimensional sigma models; largescale structure with hot dark matter and cosmic strings; the unitarization of the odderon; string thermodynamics and conservation laws; the dependence of inflationaryuniverse models on initial conditions; the delta expansion and local gauge invariance; particle physics and galaxy formation; chaotic inflation with metric and matter perturbations; grandunified theories, galaxy formation, and largescale structure; neutrino clustering in cosmicstringinduced wakes; and infrared approximations to nonlinear differential equations.
