Double proton tagging at the LHC as a means to discover new physics
We review the theoretical and experimental motivations behind recent
proposals to add forward proton tagging detectors to the LHC experiments as a
means to search for new physics.Comment: Talk given at the 5th Rencontres du Vietnam, 'New Views in Particle

Two-axis winch installer for heavy ducts in confined space
Two-axis winching and traversing device is used for installing liquid-propellant rocket-engine fuel and liquid oxygen suction ducts between the valves and the rocket engine on a test stand. The device raises and maneuvers the duct into the required position where it can be safely installed by mechanics
Central Exclusive Di-jet Production at the Tevatron
We perform a phenomenological analysis of dijet production in double pomeron
exchange at the Tevatron. We find that the CDF Run I results do not rule out
the presence of an exclusive dijet component, as predicted by Khoze, Martin and
Ryskin (KMR). With the high statistics CDF Run II data, we predict that an
exclusive component at the level predicted by KMR may be visible, although the
observation will depend on accurate modelling of the inclusive double pomeron
exchange process. We also compare to the predictions of the DPEMC Monte Carlo,
which contains a non-perturbative model for the central exclusive process. We
show that the perturbative model of KMR gives different predictions for the
di-jet ET dependence in the high di-jet mass fraction region than
non-perturbative models.Comment: 17 pages, 15 figure
Computing toric degenerations of flag varieties
We compute toric degenerations arising from the tropicalization of the full
flag varieties and embedded in a
product of Grassmannians. For and we
compare toric degenerations arising from string polytopes and the FFLV polytope
with those obtained from the tropicalization of the flag varieties. We also
present a general procedure to find toric degenerations in the cases where the
initial ideal arising from a cone of the tropicalization of a variety is not
prime.Comment: 35 pages, 6 figure
Diffractive production of high pt photons at HERA
We study the diffractive production of high pt photons at HERA. We have
implemented the process as a new hard sub-process in the HERWIG event generator
in order to prepare the ground for a future measurement.Comment: 4 pages, 4 figures. Contribution to the 1999 UK Phenomenology

Spin-Flavor Separation and Non-Fermi Liquid Behavior in the Multichannel Kondo Problem: A Large N Approach
We consider a generalization of the multichannel
single-impurity Kondo model which we solve analytically in the limit
, , with fixed. Non-Fermi
liquid behavior of the single electron Green function and of the local spin and
flavor susceptibilities occurs in both regimes, and , with
leading critical exponents {\em identical} to those found in the conformal
field theory solution for {\em all} and (with ). We explain
this remarkable agreement and connect it to ``spin-flavor separation", the
essential feature of the non-Fermi-liquid fixed point of the multichannel Kondo
problem.Comment: 14 pages, 1 Figure (Poscript file attached), Revte
