A Letter of Intent for MATHUSLA: a dedicated displaced vertex detector above ATLAS or CMS
Cristiano Alpigiani, Austin Ball, Liron Barak +61
In this Letter of Intent (LOI) we propose the construction of MATHUSLA (MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles), a dedicated large-volume displaced vertex dete…
The CMS Magnetic Field Measuring and Monitoring Systems
Vyacheslav Klyukhin, Austin Ball, Felix Bergsma +11
This review article describes the performance of the magnetic field measuring and monitoring systems for the Compact Muon Solenoid (CMS) detector. To cross-check the magnetic flux…
Recent Progress and Next Steps for the MATHUSLA LLP Detector
Cristiano Alpigiani, Juan Carlos Arteaga-Velázquez, Austin Ball +93
We report on recent progress and next steps in the design of the proposed MATHUSLA Long Lived Particle (LLP) detector for the HL-LHC as part of the Snowmass 2021 process. Our under…
A Letter of Intent to Install a milli-charged Particle Detector at LHC P5
Austin Ball, Jim Brooke, Claudio Campagnari +17
In this LOI we propose a dedicated experiment that would detect "milli-charged" particles produced by pp collisions at LHC Point 5. The experiment would be installed during LS2 in…
The MATHUSLA Test Stand
Maf Alidra, Cristiano Alpigiani, Austin Ball +23
The rate of muons from LHC collisions reaching the surface above the ATLAS interaction point is measured and compared with expected rates from decays of and bosons and…
An Update to the Letter of Intent for MATHUSLA: Search for Long-Lived Particles at the HL-LHC
Cristiano Alpigiani, Juan Carlos Arteaga-Velázquez, Austin Ball +80
We report on recent progress in the design of the proposed MATHUSLA Long Lived Particle (LLP) detector for the HL-LHC, updating the information in the original Letter of Intent (Lo…
MATHUSLA: A Detector Proposal to Explore the Lifetime Frontier at the HL-LHC
Henry Lubatti, Cristiano Alpigiani, Juan Carlos Arteaga-Velázquez +60
The observation of long-lived particles at the LHC would reveal physics beyond the Standard Model, could account for the many open issues in our understanding of our universe, and…
Using the Standard Linear Ramps of the CMS Superconducting Magnet for Measuring the Magnetic Flux Density in the Steel Flux Return Yoke
Vyacheslav Klyukhin, Benoit Curé, Nicola Amapane +6
The principal difficulty in large magnetic systems having an extensive flux return yoke is to characterize the magnetic flux distribution in the yoke steel blocks. Continuous measu…
Comparison of Two Detector Magnetic Systems for the Future Circular Hadron-Hadron Collider
Vyacheslav Klyukhin, Austin Ball, Christophe Paul Berriaud +9
The conceptual design study of a Future Circular hadron-hadron Collider (FCC-hh) to be con-structed at CERN with a center-of-mass energy of the order of 100 TeV requires supercondu…
Design, Implementation and First Measurements with the Medipix Neutron Camera in CMS
Dorothea Pfeiffer, Austin Ball, Alan Bell +13
The Medipix detector is the first device dedicated to measuring mixed-field radiation in the CMS cavern and able to distinguish between different particle types. Medipix2-MXR chips…
