Autor: Bechtle, Philip, Belkner, Sebastian, Dercks, Daniel, Hamer, Matthias, Keller, Tim, Krämer, Michael, Sarrazin, Björn, Schütte-Engel, Jan, Tattersall, Jamie

SCYNet (SUSY Calculating Yield Net) is a tool for testing supersymmetric models against LHC data. It uses neural network regression for a fast evaluation of the profile likelihood ratio. Two neural network approaches have been developed: one network

We investigate the constrained Minimal Supersymmetric Standard Model (cMSSM) in the light of constraining experimental and observational data from precision measurements, astrophysics, direct supersymmetry searches at the LHC and measurements of the

Constrained Supersymmetry after the Higgs Boson Discovery: A global analysis with Fittino

Autor: Bechtle, Philip, Desch, Klaus, Dreiner, Herbert K., Hamer, Matthias, Krämer, Michael, O'Leary, Ben, Porod, Werner, Prudent, Xavier, Sarrazin, Björn, Stefaniak, Tim, Uhlenbrock, Mathias, Wienemann, Peter

We present preliminary results from the latest global fit analysis of the constrained minimal supersymmetric standard model (CMSSM) performed within the Fittino framework. The fit includes low-energy and astrophysical observables as well as collider

We investigate the implications for supersymmetry from an assumed absence of any signal in the first period of LHC data taking at 7 TeV center-of-mass energy and with 1 to 7 fb^(-1) of integrated luminosity. We consider the zero-lepton plus four jets

A new method providing general consistency constraints for Beyond-the-Standard-Model (BSM) theories, using measurements at particle colliders, is presented. The method, `Constraints On New Theories Using Rivet', Contur, exploits the fact that particl
