Dark Matter Benchmark Models for Early LHC Run-2 Searches: Report of the ATLAS/CMS Dark Matter Forum

This document is the final report of the ATLAS-CMS Dark Matter Forum, a forum organized by the ATLAS and CMS collaborations with the participation of experts on theories of Dark Matter, to select a minimal basis set of dark matter simplified models that should support the design of the early LHC Run-2 searches. A prioritized, compact set of benchmark models is proposed, accompanied by studies of the parameter space of these models and a repository of generator implementations. This report also addresses how to apply the Effective Field Theory formalism for collider searches and present the results of such interpretations.

Search for the Standard Model Higgs boson in WH -> lnubb and H -> WW(*) -> lnulnu channels at ATLAS

Results for the Standard Model Higgs boson search by the ATLAS experiment in the WH -> lnubb and H -> WW(*) -> lnulnu channels are presented. The results are based on 1.04 fb^-1 of data from pp collisions at sqrt(s) = 7 TeV produced by the LHC in 2011. No evidence is found for the Standard Model Higgs boson in either decay mode. The WH -> lnubb channel is not yet sensitive to the Standard Model Higgs, while the H -> WW(*) -> lnulnu channel excludes the Standard Model Higgs in the range of 158 < m_H < 186 GeV at the 95% confidence level.

Measurement of the Z boson transverse momentum spectrum on ATLAS with early data

One of the benchmark analyses to be performed with the first data at the CERN Large Hadron Collider will be the measurement of the Z boson transverse momentum spectrum. In this article, I present a prospective analysis for this measurement in the dimuon channel on the ATLAS experiment. The analysis uses simulated datasets at a center-of-mass energy of 10 TeV. After summarizing the motivations for the measurement, I discuss the Z boson selection criteria, possible physics backgrounds, and background removal techniques with a focus on data-driven background determination. I conclude with an outlook toward the collision data expected in 2009-10.
