Beyond the Desert: Tevatron and LHC Results on Searches for Physics Beyond the Standard Model
No full textThis 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
Orbital compactness and asymptotic behaviour of nonlinear parabolic systems with functionals
No full textSynopsisWeakly coupled semilinear parabolic systems of the form with homogeneous boundary conditions are studied. The nonlinear function g: C([−r, 0] × Ω ℝn) → ℝn is assumed to be locally Lipschitz continuous with r≧0 a given real number and Ω ⊂ ℝm a bounded domain, , ut for t ≧ 0 is denned by ut (σ, ξ) = u(t + σ, ξ), − r ≦σ ≦ 0 ξ ∊Ω and A is a uniformly elliptic second order diagonal operator. Let u be a bounded classical solution. We first establish precompactness results for the orbit of u in several function spaces. Using these results and assuming that a Liapunov function V is known for the corresponding ordinary functional differential equation ż =g(zt), we then show under some general conditions that the limit set ω+ (as t→∞) of u consists of spatially homogeneous functions only. Moreover, ω+ is invariant with respect to z = g(z,) and V = 0 on ω+. The proof uses a Liapunov function for the full system whichis obtained from V via a simple construction (cf. (3.3)). The theory is illustrated with an example.</jats:p
Über die C<sup>2</sup>-Kompaktheit der Bahn von Lösungen semflinearer parabolischer Systeme
No full textSynopsisThe semilinear parabolic systemut+A(x, D)u=g(u) in (0, ∞) × Ω, Ω⊂ℝnbounded,u∈ ℝN, with homogeneous boundary conditionsB(x, D)u=0 on (0, ∞)×∂Ω is considered. The non-linearitygis assumed to be locally Lipschitz-continuous. It is shown that the orbit of a bounded regular solutionuis relatively compact in.</jats:p
Searches for Supersymmetry with the ATLAS Detector
No full textThis 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.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.

Recent results on SUSY and BSM searches from ATLAS and CMS
No full textThis is a draft of my slides for Pheno2011. The time allocated was originally 45 minutes, but now has been cut back to 30 minutes. There might be too much material here; some of it might have to go to the backup pages

New result on K{sup +} {r_arrow} {pi}{sup +} {nu}{bar {nu}} from BNL E787
No full textE787 at BNL has reported evidence for the rare decay K{sup +} {r_arrow} {pi}{sup +}{nu}{bar {nu}}, based on the observation of one candidate event. In this paper, we present the result of analyzing a new dataset of comparable sensitivity to the published result
