Extended Gauge Models and at the NLC
We briefly discuss two possible manifestations of the lepton number violating
reaction , which probes the masses and mixings of
heavy Majorana neutrinos, at the Next Linear Collider(NLC). Cross sections for
this process are shown to be potentially quite large at center of mass energies
of order 1-1.5 TeV. (Talk presented at the Santa Cruz Workshop on
Physics at the NLC, University of California, Santa Cruz, September 4-5, 1995.)Comment: 9 pages, uuencoded compressed postscript file. To obtain a copy of

SUSY Without Prejudice at Linear Colliders
We explore the physics of the general CP-conserving MSSM with Minimal Flavor
Violation, the pMSSM. The 19 soft SUSY breaking parameters are chosen so to
satisfy all existing experimental and theoretical constraints assuming that the
WIMP is the lightest neutralino. We scan this parameter space twice using both
flat and log priors and compare the results which yield similar conclusions.
Constraints from both LEP and the Tevatron play an important role in obtaining
our final model samples. Implications for future TeV-scale linear
colliders(LC) are discussed.Comment: 6 pages, 3 figs. Talk given at LCWS08, Chicago, IL, USA,

Upgrade of the ATLAS Liquid Argon Calorimeters for the High-Luminosity LHC
The increased particle flux at the high luminosity phase of the Large Hadron
Collider (HL-LHC), with instantaneous luminosities of up to 7.5 times the
original design value, will have an impact on many sub-systems of the ATLAS
detector. This contribution highlights the particular impacts on the ATLAS
liquid argon calorimeter system, together with an overview of the various
upgrade plans leading up to the HL-LHC. The higher luminosities are of
particular importance for the forward calorimeters (FCal), where the expected
increase in the ionization load poses a number of problems that can degrade the
FCal performance such as beam heating and space-charge effects in the liquid
argon gaps and high-voltage drop due to increased current drawn over the
current-limiting resistors. A proposed FCal replacement as a way to counter
some of these problems is weighed against the risks associated with the
replacement. To further mitigate the effects of increased pile-up, the
installation of a high-granularity timing detector at the front face of each
end-cap cryostat is also currently under consideration. Several different
sensor technologies and layouts are being investigated.Comment: 7 pages, 12 figures, Proceedings of the IEEE Nuclear Science
