Charged Particle Tracking in Real Time using Full-Mesh Data Delivery Architecture and Associative Memory Techniques
/ Ajuha, Sudha (Sao Paulo State U.) ; Shinoda, Ailton Akira (Sao Paulo State U.) ; Ramalho, Lucas Arruda (Sao Paulo State U.) ; Baulieu, Guillaume (IP2I, Lyon) ; Boudoul, Gaelle (IP2I, Lyon) ; Casarsa, Massimo (INFN, Trieste) ; Cascadan, Andre (Sao Paulo State U.) ; Clement, Emyr (Bristol U.) ; de Paiva, Thiago Costa (Sao Paulo State U.) ; Das, Souvik (Florida U.) et al.
We present a flexible and scalable approach to address the challenges of charged particle track reconstruction in real-time event filters (Level-1 triggers) in collider physics experiments. The method described here is based on a full-mesh architecture for data distribution and relies on the Associative Memory approach to implement a pattern recognition algorithm that quickly identifies and organizes hits associated to trajectories of particles originating from particle collisions.

Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider
/ Alimena, Juliette (Ohio State U.) ; Beacham, James (Duke U.) ; Borsato, Martino (Heidelberg U.) ; Cheng, Yangyang (Cornell U., LNS) ; Cid Vidal, Xabier (Santiago de Compostela U.) ; Cottin, Giovanna (Adolfo Ibanez U. ; Chile U., Catolica ; Taiwan, Natl. Taiwan U.) ; De Roeck, Albert (CERN) ; Desai, Nishita (Tata Inst.) ; Curtin, David (Toronto U.) ; Evans, Jared A. (Cincinnati U.) et al.
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Hadron Collider (LHC) at CERN, these long-lived particles (LLPs) can decay far from the interaction vertex of the primary proton-proton collision. [...]

LHC Dark Matter Working Group: Next-generation spin-0 dark matter models
/ LHC Dark Matter Working Group Collaboration
Dark matter (DM) simplified models are by now commonly used by the ATLAS and CMS Collaborations to interpret searches for missing transverse energy ($E_T^\mathrm{miss}$). The coherent use of these models sharpened the LHC DM search program, especially in the presentation of its results and their comparison to DM direct-detection (DD) and indirect-detection (ID) experiments.

Recommendations of the LHC Dark Matter Working Group: Comparing LHC searches for heavy mediators of dark matter production in visible and invisible decay channels
/ Albert, Andreas (Aachen, Tech. Hochsch.) ; Backović, Mihailo (Louvain U., CP3) ; Boveia, Antonio (Ohio State U.) ; Buchmueller, Oliver (Imperial Coll., London) ; Busoni, Giorgio (Melbourne U.) ; De Roeck, Albert (Antwerp U. ; CERN ; Gottingen U.) ; Doglioni, Caterina (Lund U.) ; DuPree, Tristan (NIKHEF, Amsterdam) ; Fairbairn, Malcolm (King's Coll. London) ; Genest, Marie-Hélène (LPSC, Grenoble) et al.
Weakly-coupled TeV-scale particles may mediate the interactions between normal matter and dark matter. If so, the LHC would produce dark matter through these mediators, leading to the familiar "mono-X" search signatures, but the mediators would also produce signals without missing momentum via the same vertices involved in their production.

Towards the next generation of simplified Dark Matter models
/ Albert, Andreas (Aachen, Tech. Hochsch.) ; Bauer, Martin (Heidelberg U.) ; Brooke, Jim (Bristol U.) ; Buchmueller, Oliver (Imperial Coll., London) ; Cerdeño, David G. (Durham U.) ; Citron, Matthew (Imperial Coll., London) ; Davies, Gavin (Imperial Coll., London) ; De Cosa, Annapaola (Zurich U.) ; De Roeck, Albert (CERN ; Antwerp U.) ; De Simone, Andrea (INFN, Trieste) et al.
This White Paper is an input to the ongoing discussion about the extension and refinement of simplified Dark Matter (DM) models. Based on two concrete examples, we show how existing simplified DM models (SDMM) can be extended to provide a more accurate and comprehensive framework to interpret and characterise collider searches.

Phys. ; UC, Santa Cruz (main)) ; De Roeck, Albert (U. Antwerp (main) ; CERN) ; De Simone, Andrea (SISSA, Trieste ; INFN, Trieste) ; Doglioni, Caterina (ed.) (Lund Inst. Tech.) ; Dolan, Matthew J. (ARC, CoEPP, Australia) ; Genest, Marie-Helene (LPSC, Grenoble) ; Hahn, Kristian (ed.) (Northwestern U.) et al.
This document summarises the proposal of the LHC Dark Matter Working Group on how to present LHC results on $s$-channel simplified dark matter models and to compare them to direct (indirect) detection experiments..
