We present the current status of MATHUSLA (MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles) long-lived particle (LLP) detector at HL-LHC, covering design, fabrication and installation CERN Point 5. MATHUSLA40 is a 40 m-scale with an air-filled decay volume that instrumented scintillator tracking detectors, to be located near CMS. Its large size, close proximity CMS interaction point about 100 m rock shielding from LHC backgrounds allows it detect LLP production rates lifetimes...
We report on recent progress and next steps in the design of proposed MATHUSLA Long Lived Particle (LLP) detector for HL-LHC as part Snowmass 2021 process. Our understanding backgrounds has greatly improved, aided by detailed simulation studies, significant R&D been performed designing scintillator detectors their performance. The collaboration is track to complete a Technical Design Report, there are many opportunities interested new members contribute towards goal constructing time...
In the domain of high-energy physics (HEP), query languages in general and SQL particular have found limited acceptance. This is surprising since HEP data analysis matches model well: fully structured queried using mostly standard operators. To gain insights on why this case, we perform a comprehensive six diverse, general-purpose processing platforms an benchmark. The result evaluation interesting rather complex picture existing solutions: Their vary greatly how natural concise patterns can...
We report on recent progress in the design of proposed MATHUSLA Long Lived Particle (LLP) detector for HL-LHC, updating information original Letter Intent (LoI), see CDS:LHCC-I-031, arXiv:1811.00927. A suitable site has been identified at LHC Point 5 that is closer to CMS Interaction (IP) than assumed LoI. The decay volume increased from 20 m 25 height. Engineering studies have made order locate much below ground, bringing even IP. With these changes, a 100 x same physics reach large c$\tau$...
In this Letter of Intent (LOI) we propose the construction MATHUSLA (MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles), a dedicated large-volume displaced vertex detector HL-LHC on surface above ATLAS or CMS. Such detector, which can be built using existing technologies with reasonable budget in time upgrade, could search neutral long-lived particles (LLPs) up to several orders magnitude better sensitivity than CMS, while also acting as cutting-edge cosmic ray telescope at CERN...
Abstract The long-term sustainability of the high-energy physics (HEP) research software ecosystem is essential to field. With new facilities and upgrades coming online throughout 2020s, this will only become increasingly important. Meeting challenge requires a workforce with combination HEP domain knowledge advanced skills. required skills fall into three broad groups. first fundamental generic engineering (e.g., Unix, version control, C++, continuous integration). second domain-specific...
The traditional approach in HEP analysis software is to loop over every event and object via the ROOT framework. This method follows an imperative paradigm, which code tied storage format steps of execution. A more desirable strategy would be implement a declarative language, such that medium execution are not included abstraction model. will become increasingly important managing large dataset collected by LHC HL-LHC. new description language (ADL) inspired functional programming, FuncADL,...
Abstract In the domain of high-energy physics (HEP), general-purpose query languages have found little adoption in analysis. This is surprising regarding SQL-based systems, as HEP data analysis matches SQL’s processing model well: fully structured and makes use predominantly standard operators. To better understand situation, we select six engines, from both SQL NoSQL domain, analyze their performance, scalability, usability analysis, employing tools baseline. We also identify a set core...
The second workshop on the HEP Analysis Ecosystem took place 23-25 May 2022 at IJCLab in Orsay, to look progress and continuing challenges scaling up analysis meet needs of HL-LHC DUNE, as well very pressing LHC Run 3 analysis. was themed around six particular topics, which were felt capture key questions, opportunities challenges. Each topic arranged a plenary session introduction, often with speakers summarising state-of-the art next steps for This then followed by parallel sessions, much...
