Natural SUSY Endures

TL;DR: The first 1 fb−1 of LHC searches have set impressive limits on new colored particles decaying to missing energy, and the implication of these searches for naturalness in supersymmetry (SUSY) is addressed in this paper.

Searches for long-lived charged particles in pp collisions at sqrt(s) = 7 and 8 TeV

S. Chatrchyan, +2270 more
TL;DR: In this article, results of searches for heavy stable charged particles produced in pp collisions at 7 and 8 TeV are presented corresponding to an integrated luminosity of 5.0 and 18.8 inverse femtobarns, respectively.

Constrained Supersymmetry after two years of LHC data: a global view with Fittino

TL;DR: In this paper, the authors performed global fits to the parameters of the constrained minimal supersymmetric standard model (CMSSM) and a variant with non-universal Higgs masses (NUHM1) and found that the description of low-energy observables, (g-2)(mu) in particular, and the non-observation of SUSY at the LHC become more and more incompatible within the CMSSM.

Excluding electroweak baryogenesis in the MSSM

TL;DR: In this paper, it was shown that the Higgs searches are still highly constraining, excluding the entire EWBG parameter space at greater than 90% confidence level in the (non-)decoupling limit.

Search for heavy long-lived charged particles in pp collisions at √s=7 TeV

S. Chatrchyan, +2190 more
- 18 Jul 2012 - 
TL;DR: In this article, the results of a search for heavy long-lived charged particles produced in pp collisions at the LHC were described and the results were used to establish cross section limits as a function of mass within the context of models with longlived gluinos, scalar top quarks and scalar taus.

New generation of parton distributions with uncertainties from global QCD analysis

TL;DR: In this paper, a new generation of parton distribution functions with increased precision and quantitative estimates of uncertainties is presented, using a recently developed eigenvector-basis approach to the hessian method, which provides the means to quickly estimate the uncertainties of a wide range of physical processes at these high-energy hadron colliders, based on current knowledge of the parton distributions.

The ATLAS Experiment at the CERN Large Hadron Collider

TL;DR: In this paper, the ATLAS experiment is described as installed in i ts experimental cavern at point 1 at CERN and a brief overview of the expec ted performance of the detector is given.

HERWIG 6: an event generator for hadron emission reactions with interfering gluons (including supersymmetric processes)

TL;DR: HERWIG as mentioned in this paper is a general-purpose Monte Carlo event generator, which includes the simulation of hard lepton-lepton, leptonhadron and hadron-hadron scattering and soft hadronhadron collisions in one package.

The ATLAS Simulation Infrastructure

Georges Aad, +2585 more
TL;DR: The simulation software for the ATLAS Experiment at the Large Hadron Collider is being used for large-scale production of events on the LHC Computing Grid, including supporting the detector description, interfacing the event generation, and combining the GEANT4 simulation of the response of the individual detectors.

Theories with Gauge-Mediated Supersymmetry Breaking

TL;DR: Theoretically, these theories allow for a natural suppression of flavour violations in the supersymmetric sector and have very distinctive phenomenological features as discussed by the authors, and the experimental implications of these theories have been discussed.
