Search for supersymmetry in top final states at CMS
Authors
Abstract:
A search for SUSY using the top quark plus missing transverse energy (MET), in a low mass mSUGRA test point is performed. A two–constraints kinematic fit is utilized to extract the top quark, either b-jet the ones that is recognizable or it is not recognizable. It is shown that for point LM1, for the former situation, a 5σ excess can be achieved with 30 pb-1 and for the latter situation, it can be observed with 9.6 pb-1. The ratio of the final signal over background for both situations is 12.0.

Search for Supersymmetry at CMS in all-hadronic final states
Searches for Supersymmetry in final states with jets and missing transverse energy are presented. They were performed with data samples corresponding to up to 1.1 fb−1 of integrated luminosity collected by the CMS experiment at the LHC in pp-collisions at a center-of-mass energy of 7 TeV. No excess of events was observed above the expected Standard Model background, which has been measured usin...

Among the most promising prospects for a theory of physics beyond the standard model is supersymmetry. In this talk, the latest results from the CMS experiment at the LHC on searches for supersymmetry produced through through strong production and electroweak production channels are presented using 20/fb of data from the 8 TeV LHC run, with particular focus on gluino and stop searches. Presente...

CMS has searched for supersymmetry using the full dataset recorded until the end of 2012, at a centerof-mass energy of 8 TeV corresponding to an integrated luminosity of 20 fb-1. The observations are consistent with the expectations from the standard model. CMS maintains a broad spectrum of search strategies that target a wide range of supersymmetric scenarios. A selection of results from very ...
full textSearch for New Physics in All-Hadronic Final States at CMS
Searches for new physics in hadronic final states are performed using data up to 1 f b −1 collected by the CMS experiment at the LHC at a collsion energy of √ s=7 TeV. No new physics is found and upper limits are set for various models: ADD, unparticle, string resonance, excited quarks, axigluons, Randall-Sundrum gravitons, RPV SUSY gluino, as well as black holes.

We report results of a search for supersymmetry (SUSY) with gauge-mediated symmetry breaking in di-photon events collected by the D0 experiment at the Fermilab Tevatron Collider in 2002–2006. In 1.1 fb−1 of data, we find no significant excess beyond the background expected from the standard model and set the most stringent lower limits to date for a standard benchmark model on the lightest neut...

CMS has searched for new physics in the fully hadronic final state. Because of the large branching fraction into quarks compared to charged leptons, analyses in this channel have generally large acceptances and therefore competitive sensitivities. The result of three independent and complementary analysis strategies are presented. The ”Razor" analysis using 36 pb−1 of luminosity and the αT anal...
