The discovery by the ATLAS and CMS experiments of a new boson with mass around 125 GeV measured properties compatible those Standard-Model Higgs boson, coupled absence discoveries phenomena beyond Standard Model at TeV scale, has triggered interest in ideas for future factories. A circular e+e- collider hosted 80 to 100 km tunnel, TLEP, is among most attractive solutions proposed so far. It clean experimental environment, produces high luminosity top-quark, W Z studies, accommodates multiple...
We present the activities of `New Physics' working group for `Physics at TeV Colliders' workshop (Les Houches, France, 5--23 June, 2017). Our report includes new physics studies connected with Higgs boson and its properties, direct search strategies, reinterpretation LHC results in building viable models computational tool developments.
This report summarises the physics opportunities in search and study of beyond Standard Model at a 100 TeV pp collider.
This is the summary and introduction to proceedings contributions for Les Houches 2009 "Tools Monte Carlo" working group.
We consider a class of on-shell constrained mass variables that are 3+1 dimensional generalizations the Cambridge M T2 variable and automatically incorporate various assumptions about underlying event topology. The presence additional constraints causes their kinematic distributions to exhibit sharper endpoints than usual distribution. study mathematical properties these new variables, e.g., uniqueness solution selected by minimization over invisible particle 4-momenta. then use this...
The work contained herein constitutes a report of the ``Beyond Standard Model'' working group for Workshop "Physics at TeV Colliders", Les Houches, France, 26 May--6 June, 2003. research presented is original, and was performed specifically workshop. Tools calculations in minimal supersymmetric standard model are presented, including comparison dark matter relic density predicted by public codes. Reconstruction particle masses LHC future linear collider facility examined. Less orthodox...
The search for light stops is of paramount importance, both in general as a promising path to the discovery beyond standard model physics and more specifically way evaluating success naturalness paradigm. While LHC experiments have ruled out much relevant parameter space, there are "stop gaps", i.e., values sparticle masses which existing analyses relatively little sensitivity stops. We point that techniques involving on-shell constrained M_2 variables can do enhance this region hence help...
Reconstructed mass variables, such as M 2, 2C , * and 2 play an essential role in searches for new physics at hadron colliders. The calculation of these variables generally involves constrained minimization a large parameter space, which is numerically challenging. We provide C++ code, Optimass, interfaces with the Minuit library to perform this using Augmented Lagrangian Method. code can be applied arbitrarily general event topologies, thus allowing user significantly extend existing set...
The inclusive same-sign dilepton channel is already recognized as a promising discovery signature for supersymmetry in the early days of LHC. We point out that it can also be used precision measurements sparticle masses after initial discovery. As an illustration, we consider LM6 CMS study minimal supergravity, where leptons most often result from chargino decays to sneutrinos. discuss three different techniques determining and sneutrino manner, i.e., using only two well measured lepton...
This work summarises the present understanding of expected MSSM SUSY Higgs reach for CMS. Many studies presented here result from detailed detector simulations incorporating final CMS design and response. With 30 fb-1 h -> gamma,gamma bb channels allow to cover most parameter space. For massive A,H,H+ states A,H tau,tau H+ tau,nu turn out be profitable ones in terms mass space coverage. Consequently has made a big effort trigger efficiently on taus. Provided neutralinos sleptons are not...
