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...
We present an extension of the expert mode MadAnalysis 5 program dedicated to design or reinterpretation high-energy physics collider analyses. detail predefined classes, functions and methods available user emphasize most recent developments. The latter include possible definition multiple sub-analyses a novel user-friendly treatment for selection criteria. illustrate this approach by two concrete examples: CMS search supersymmetric partners top quark phenomenological analysis targeting...
We describe the Resummino package, a C++ and Fortran program dedicated to precision calculations in framework of gaugino slepton pair production at hadron colliders. This code allows calculate transverse-momentum invariant-mass distributions as well total cross sections by combining next-to-leading order predictions obtained means perturbative QCD with resummation large logarithmic contributions arising small region close threshold. The results computed this way benefit from reduced...
This Report summarizes the proceedings of 2015 Les Houches workshop on Physics at TeV Colliders. Session 1 dealt with (I) new developments relevant for high precision Standard Model calculations, (II) PDF4LHC parton distributions, (III) issues in theoretical description production Higgs bosons and how to relate experimental measurements, (IV) a host phenomenological studies essential comparing LHC data from Run I predictions projections future measurements II, (V) Monte Carlo event generators.
We present the implementation, in MadAnalysis 5 framework, of several ATLAS and CMS searches for supersymmetry data recorded during first run LHC. provide extensive details on validation our implementations propose to create a public analysis database within this framework.
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at weak scale. When produced experiments such as Large Hadron Collider (LHC) CERN, these long-lived (LLPs) decay far from interaction vertex of primary proton-proton collision. Such LLP signatures distinct those promptly decaying targeted by majority searches for new physics LHC, often requiring customized techniques identify, example, significantly displaced vertices, tracks with...

Abstract We introduce a new simplified fast detector simulator in the MadAnalysis 5 platform. The Python -like interpreter of programme has been augmented by commands allowing for parametrisation through smearing and efficiency functions. On run time, an associated C++ code is automatically generated executed to produce reconstructed-level events. In addition, we have extended recasting infrastructure support our emulator, provide predefined LHC configurations. compared predictions obtained...
The ATLAS and CMS collaborations have recently presented results of searches for compressed electroweakinos in final states including soft leptons. These are sensitive to mass splittings ranging from quite small values about 5 GeV O(10) GeV, which endemic scenarios with wino-like higgsino-like lightest supersymmetric particles (LSPs). While all experimental exhibit apparently compatible mild excesses, these soft-lepton analyses, taken together disappearing-track targeting much smaller...

This can be employed re-weight any matrix elements relevant for $t\bar{t}$ production and decay processes where colour-singlet top-antitop pair is produced $S$-wave threshold. As an example, we study $\eta_t$ states gluon fusion channel LHC, combining re-weighted with parton showering.
