Search for Higgs and New Phenomena at Colliders
The present status of searches for the Higgs boson(s) and new phenomena is
reviewed. The focus is on analyses and results from the current runs of the
HERA and Tevatron experiments. The LEP experiments have released their final
combined MSSM Higgs results for this conference. Also included are results from
sensitivity studies of the LHC experiments and lepton flavour violating
searches from the B factories, KEKB and PEP-II.Comment: XXII International Symposium on Lepton-Photon Interactions at High

What if the Higgs Boson Weighs 115 GeV?
If the Higgs boson indeed weighs about 114 to 115 GeV, there must be new
physics beyond the Standard Model at some scale \la 10^6 GeV. The most
plausible new physics is supersymmetry, which predicts a Higgs boson weighing
\la 130 GeV. In the CMSSM with R and CP conservation, the existence, production
and detection of a 114 or 115 GeV Higgs boson is possible if \tan\beta \ga 3.
However, for the radiatively-corrected Higgs mass to be this large, sparticles
should be relatively heavy: m_{1/2} \ga 250 GeV, probably not detectable at the
Tevatron collider and perhaps not at a low-energy e^+ e^- linear collider. In
much of the remaining CMSSM parameter space, neutralino-stau coannihilation is
important for calculating the relic neutralino density, and we explore
implications for the elastic neutralino-nucleon scattering cross section.Comment: 17 pages, 5 eps figure

Decoupling Transition I. Flux Lattices in Pure Layered Superconductors
We study the decoupling transition of flux lattices in a layered
superconductors at which the Josephson coupling J is renormalized to zero. We
identify the order parameter and related correlations; the latter are shown to
decay as a power law in the decoupled phase. Within 2nd order renormalization
group we find that the transition is always continuous, in contrast with
results of the self consistent harmonic approximation. The critical temperature
for weak J is ~1/B, where B is the magnetic field, while for strong J it
is~1/sqrt{B} and is strongly enhanced. We show that renormaliztion group can be
used to evaluate the Josephson plasma frequency and find that for weak J it
is~1/BT^2 in the decoupled phase.Comment: 14 pages, 5 figures. New sections III, V. Companion to following
