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...

The coherent use of these sharpened LHC DM search program, especially in presentation its results their comparison direct-detection (DD) indirect-detection (ID) experiments. However, community has been aware limitations models, particular lack theoretical consistency some them restricted phenomenology leading relevance only a small subset...
The PICASSO collaboration observed for the first time a significant difference between acoustic signals induced by neutrons and alpha particles in detector based on superheated liquids. This new discovery offers possibility of improved background suppression could be especially useful dark matter experiments. effect may attributed to formation multiple bubbles tracks, compared single nucleations created neutron-induced recoils.
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.
Weakly-coupled TeV-scale particles may mediate the interactions between normal matter and dark matter. If so, LHC would produce through these mediators, leading to familiar "mono-X" search signatures, but mediators also signals without missing momentum via same vertices involved in their production. This document from Dark Matter Working Group suggests how compare searches for two types of case vector axial-vector based on a workshop that took place September 19/20, 2016 subsequent...
This is the third out of five chapters final report [1] Workshop on Physics at HL-LHC, and perspectives HE-LHC [2]. It devoted to study potential, in search for Beyond Standard Model (BSM) physics, High Luminosity (HL) phase LHC, defined as $3~\mathrm{ab}^{-1}$ data taken a centre-of-mass energy $14~\mathrm{TeV}$, possible future upgrade, Energy (HE) $15~\mathrm{ab}^{-1}$ $27~\mathrm{TeV}$. We consider large variety new physics models, both simplified model fashion more model-dependent one....
In this work, we consider the case of a strongly coupled dark/hidden sector, which extends Standard Model (SM) by adding an additional non-Abelian gauge group. These extensions generally contain matter fields, much like SM quarks, and fields similar to gluons. We focus on exploration such sectors where dark particles are produced at LHC through portal undergo rapid hadronization within sector before decaying back, least in part potentially with sizeable lifetimes, particles, giving range...

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.
We report new results obtained from calibrations of superheated liquid droplet detectors used in dark matter searches with different radiation sources (n, α, γ). In particular, were spiked α-emitters located inside and outside the droplets. It is shown that responses have temperature thresholds, depending on whether α-particles or recoil nuclei create signals. The measured threshold for recoiling 210Pb 214Po α-decays was found to be agreement test beam measurements using mono-energetic...
The increase of the particle flux at HL-LHC with instantaneous luminosities up to L=7.5 × 10 34 cm −2 s −1 will have a severe impact on ATLAS detector reconstruction and trigger performance. end-cap forward region where liquid Argon calorimeter has coarser granularity inner tracker poorer momentum resolution be particularly affected. A High Granularity Timing Detector installed in front calorimeters help charged-particle luminosity measurement. This low angle is introduced augment new...

The comparison of the results direct detection Dark Matter, obtained with various target nuclei, requires model-dependent, or even arbitrary, assumptions. Indeed, to draw conclusions either spin-dependent (SD) spin-independent (SI) interaction has be neglected. In light null from supersymmetry searches at LHC, squark sector is pushed high masses. We show that for a TeV scale, framework used extract contraints can redefined as number free parameters reduced. Moreover, correlation observed...
