This document is the final report of ATLAS-CMS Dark Matter Forum, a forum organized by ATLAS and CMS collaborations with participation experts on theories Matter, to select minimal basis set dark matter simplified models that should support design early LHC Run-2 searches. A prioritized, compact benchmark proposed, accompanied studies parameter space these repository generator implementations. also addresses how apply Effective Field Theory formalism for collider searches present results...
This document a outlines set of simplified models for dark matter and its interactions with Standard Model particles. It is intended to summarize the main characteristics that these have when applied searches at LHC, provide number useful expressions reference. The list includes both s-channel t-channel scenarios. For s-channel, spin-0 spin-1 mediations are discussed, also realizations where Higgs particle provides portal between visible sectors. guiding principles underpinning proposed...
We outline and investigate a set of benchmark simplified models with the aim providing minimal simple framework for an interpretation existing forthcoming searches dark matter particles at LHC. The we consider provide microscopic QFT descriptions interactions between Standard Model partons sector mediated by four basic types messenger fields: scalar, pseudo-scalar, vector or axial-vector. Our are characterised to five parameters, including mediator mass width, effective coupling(s). In gluon...
Motivated by aLIGO's recent discovery of gravitational waves we discuss signatures new physics that could be seen at ground and space-based interferometers. We show a first order phase transition in dark sector would lead to detectable wave signal future experiments, if the has occurred temperatures few orders magnitude higher than electroweak scale. The source this case is associated with dynamics expanding colliding bubbles early universe. At same time point out topological defects, such...
This report summarises the physics opportunities in search and study of beyond Standard Model at a 100 TeV pp collider.
The Seiberg-Witten solution of $N=2$ supersymmetric SU(2) gauge theory may be viewed as a prediction for the infinite family constants {${\mathcal{F}}_{n}$} measuring $n$-instanton contribution to prepotential $\mathcal{F}$. Here we examine instanton physics directly, in particular general self-dual topological charge $n$ constructed by Atiyah, Drinfeld, Hitchin, and Manin (ADHM). In both bosonic cases, determine large- short-distance behavior all fields this background. This allows us...
We consider classically scale-invariant extensions of the Standard Model (CSI ESM ) which stabilise Higgs potential and have good dark matter candidates. In this framework all mass scales, including electroweak masses, are generated dynamically a common origin. Abelian non-Abelian hidden sectors portally coupled to SM with without real singlet scalar. perform careful analysis RG running determine regions in parameter space where vacuum is stabilised. After combining LHC constraints, models...
This document summarises the proposal of LHC Dark Matter Working Group on how to present results s-channel simplified dark matter models and compare them direct (indirect) detection experiments.
In this White Paper we present and discuss a concrete proposal for the consistent interpretation of Dark Matter searches at colliders in direct detection experiments. Based on specific implementation simplified models vector axial-vector mediator exchanges, demonstrates how two search strategies can be compared an equal footing.
