Beyond the Desert: Tevatron and LHC Results on Searches for Physics Beyond the Standard Model
This is a brief and limited review of searches for physics beyond the
Standard Model from the ATLAS, CDF, CMS and D0 experiments, as of the end of
July 2011. Priority is given to the most recent results and to those with the
largest integrated luminosity analyzed.Comment: 12 pages, multiple figures. For the proceedings of the DPF-2011
conference, Providence, RI, August 8-13, 201
Plans for Kaon Physics at BNL
I give an overview of current plans for kaon physics at BNL. The program is
centered on the rare decay modes K+ --> pi+ nu nubar and KL --> pi0 nu nubar.Comment: 10 pages, 8 figures. Uses espcrc2.sty. For the proceedings of HIF04:

Physics Beyond the Standard Model in ATLAS at the Startup of the LHC
This is a very brief overview of physics beyond the Standard Model that might be probed by ATLAS with integrated luminosities in the range of 0.1-1 fb-1. The discussion is limited to exotics and supersymmetry
Searches for Supersymmetry with the ATLAS Detector
This is a review of searches for supersymmetry (SUSY) with the ATLAS detector
in proton-proton collisions at a center-of-mass energy of 7 TeV at the Large
Hadron Collider at CERN. The review covers results that have been published, or
submitted for publication, up to September 2012, many of which cover the full 7
TeV data-taking period. No evidence for SUSY has been seen; some possibilities
for future directions are discussed.Comment: 15 pages, 2 figures. Invited review article for Modern Physics

Measurement of Direct Photon Emission in K^+ -> pi^+ pi^0 gamma Decay
We have performed a measurement of the K^+ -> pi^+ pi^0 gamma decay and have
observed 2 X 10^4 events. The best fit to the decay spectrum gives a branching
ratio for direct photon emission of (4.7\pm0.8\pm0.3) X 10^{-6} in the pi^+
kinetic energy region of 55 to 90 MeV and requires no component due to
interference with inner bremsstrahlung.Comment: 9 pages, 3 figures. To be submitted to PR
Improved Measurement of the K+ to pi+ nu nubar Branching Ratio
An additional event near the upper kinematic limit for K+ to pi+ nu nubar has
been observed by Experiment E949 at Brookhaven National Laboratory. Combining
previously reported and new data, the branching ratio is B(K+ to pi+ nu nubar)=
1.47 (+1.30, - 0.89) x 10-10 based on three events observed in the pion
momentum region 211<P<229 MeV/c. At the measured central value of the branching
ratio, the additional event had a signal-to-background ratio of 0.9
