Back-Reaction of Cosmological Perturbations in the Infinite Wavelength Approximation
Robert H. Brandenberger, C. S. Lam
Cosmological perturbations in an expanding universe back-react on the space-time in which they propagate. Calculations to lowest non-vanishing order in perturbation theory indicate…
Is There An Ultimate Symmetry in Physics?
C. S. Lam
A speculative discussion on the role of various symmetries in physics.
Consequences of a Z_2 Symmetry for Neutrino Oscillation
C. S. Lam
A generation symmetry in the neutrino sector predicts the atmospheric neutrino mixing to be maximal, and the MNS matrix element to be zero, consisten…
QCD Phase Shifts and Rising Total Cross-Sections
C. S. Lam
Energy dependence of total cross section is considered. It is known from the HERA data that the cross section grows with energy, and the rate of growth is an increasing func…
QCD Phase Shifts and Rising Total Cross-Sections
C. S. Lam
An attempt is made in QCD to explain the growth of total cross-sections with energy, without violating the Froissart bound. This is achieved by computing the phase shifts of elasti…
Time-Ordered Products and Exponentials
C. S. Lam
I discuss a formula decomposing the integral of time-ordered products of operators into sums of products of integrals of time-ordered commutators. The resulting factorization enabl…
