TL;DR
The report surveys signatures for physics beyond the Standard Model accessible at the LHC, with a focus on practical strategies to measure new particle masses when decays involve invisible states. It organizes the study into mass-determination techniques, SUSY phenomenology (including R-parity violation and SUSY-QCD effects), strong electroweak symmetry breaking, high-mass resonances from warped extra dimensions, and hidden-sector scenarios, providing both reviews and original results from the 2009 Les Houches workshop. Key contributions include a comparative evaluation of mass-determination methods using a common SUSY benchmark with realistic detector effects, analysis of high-mass resonances and Z' searches, and proposals for triggers and benchmarks applicable to early LHC runs at $\sqrt{s}=14\,\mathrm{TeV}$ with $L$ on the order of $10\,\mathrm{fb}^{-1}$. Overall, the paper offers a structured, multi-model resource to guide LHC search strategies and interpret potential discoveries across diverse beyond-Standard-Model scenarios.
Abstract
We present a collection of signatures for physics beyond the standard model that need to be explored at the LHC. First, are presented various tools developed to measure new particle masses in scenarios where all decays include an unobservable particle. Second, various aspects of supersymmetric models are discussed. Third, some signatures of models of strong electroweak symmetry are discussed. In the fourth part, a special attention is devoted to high mass resonances, as the ones appearing in models with warped extra dimensions. Finally, prospects for models with a hidden sector/valley are presented. Our report, which includes brief experimental and theoretical reviews as well as original results, summarizes the activities of the "New Physics" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 8-26 June, 2009).
