DeepXS: Fast approximation of MSSM electroweak cross sections at NLO
Sydney Otten, Krzysztof Rolbiecki, Sascha Caron +3
We present a deep learning solution to the prediction of particle production cross sections over a complicated, high-dimensional parameter space. We demonstrate the applicability b…
SCYNet: Testing supersymmetric models at the LHC with neural networks
Philip Bechtle, Sebastian Belkner, Daniel Dercks +6
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…
CheckMATE 2: From the model to the limit
Daniel Dercks, Nishita Desai, Jong Soo Kim +3
We present the latest developments to the CheckMATE program that allows models of new physics to be easily tested against the recent LHC data. To achieve this goal, the core of Che…
Complementarity of Resonant Scalar, Vector-Like Quark and Superpartner Searches in Elucidating New Phenomena
Anke Biekötter, JoAnne L. Hewett, Jong Soo Kim +5
The elucidation of the nature of new phenomena requires a multi-pronged approach to understand the essential physics that underlies it. As an example, we study the simplified model…
Prospects for natural SUSY
Jong Soo Kim, Krzysztof Rolbiecki, Roberto Ruiz +2
As we anticipate the first results of the 2016 run, we assess the discovery potential of the LHC to `natural supersymmetry'. To begin with, we explore the region of the model param…
Les Houches 2015: Physics at TeV colliders - new physics working group report
G. Brooijmans, C. Delaunay, A. Delgado +78
We present the activities of the 'New Physics' working group for the 'Physics at TeV Colliders' workshop (Les Houches, France, 1-19 June, 2015). Our report includes new physics stu…
The Diboson Excess: Experimental Situation and Classification of Explanations; A Les Houches Pre-Proceeding
Johann Brehmer, Gustaaf Brooijmans, Giacomo Cacciapaglia +21
We examine the `diboson' excess at TeV seen by the LHC experiments in various channels. We provide a comparison of the excess significances as a function of the mass of th…
Naughty or Nice? The Role of the `N' in the Natural NMSSM for the LHC
Jong Soo Kim, Daniel Schmeier, Jamie Tattersall
In this work, we present mass limits on gluinos and stops in a natural Next-to-Minimal Supersymmetric Standard Model (NMSSM) with a singlino as the lightest supersymmetric particle…
Symmetry Restored in Dibosons at the LHC?
Johann Brehmer, JoAnne Hewett, Joachim Kopp +2
A number of LHC resonance search channels display an excess in the invariant mass region of 1.8 - 2.0 TeV. Among them is a excess in the fully hadronic decay of a pair of…
Refining light stop exclusion limits with cross sections
Krzysztof Rolbiecki, Jamie Tattersall
If light supersymmetric top (stop) quarks are produced at the LHC and decay via on- or off-shell -bosons they can be expected to contribute to a precision cross section…
A framework to create customised LHC analyses within CheckMATE
Jong Soo Kim, Daniel Schmeier, Jamie Tattersall +1
Checkmate is a framework that allows the user to conveniently test simulated BSM physics events against current LHC data in order to derive exclusion limits. For this purpose, the…
Spying an invisible Higgs
Catherine Bernaciak, Tilman Plehn, Peter Schichtel +1
We investigate the potential of multivariate techniques to improve the LHC search for invisible Higgs decays in weak boson fusion. We find that in the coming runs the LHC will be a…
`Stop' that ambulance! New physics at the LHC?
Jong Soo Kim, Krzysztof Rolbiecki, Kazuki Sakurai +1
A number of LHC searches now display intriguing excesses. Most prominently, the measurement of the cross-section has been consistently higher than the theoreti…
CheckMATE: Confronting your Favourite New Physics Model with LHC Data
Manuel Drees, Herbi Dreiner, Jong Soo Kim +2
In the first three years of running, the LHC has delivered a wealth of new data that is now being analysed. With over 20 fb of integrated luminosity, both ATLAS and CMS have…
Contact Interactions Probe Effective Dark Matter Models at the LHC
Herbi Dreiner, Daniel Schmeier, Jamie Tattersall
Effective field theories provide a simple framework for probing possible dark matter (DM) models by reparametrising full interactions into a reduced number of operators with smalle…
Exploring QCD uncertainties when setting limits on compressed SUSY spectra
Herbert Dreiner, Michael Krämer, Jamie Tattersall
If Supersymmetry (SUSY) has a compressed spectrum the current limits from the LHC can be drastically reduced. We take possible `worst case' scenarios where combinations of the stop…
Illuminating Dark Matter at the ILC
Herbert Dreiner, Moritz Huck, Michael Krämer +2
The WIMP (weakly interacting massive particle) paradigm for dark matter is currently being probed via many different experiments. Direct detection, indirect detection and collider…
How low can SUSY go? Matching, monojets and compressed spectra
Herbi K. Dreiner, Michael Krämer, Jamie Tattersall
If supersymmetry (SUSY) has a compressed spectrum then the current mass limits from the LHC can be drastically reduced. We consider a possible 'worst case' scenario where the gluin…
