A Letter of Intent for MATHUSLA: a dedicated displaced vertex detector above ATLAS or CMS.
/ Alpigiani, Cristiano (Washington U., Seattle) ; Ball, Austin (CERN) ; Barak, Liron (Tel Aviv U.) ; Beacham, James (Ohio State U.) ; Benhammo, Yan (Tel Aviv U.) ; Cao, Tingting (Tel Aviv U.) ; Camarri, Paolo (INFN, Rome2 ; Rome U., Tor Vergata) ; Cardarelli, Roberto (INFN, Rome2) ; Rodríguez-Cahuantzi, Mario (Puebla U., Mexico) ; Chou, John Paul (Rutgers U., Piscataway) et al.
In this Letter of Intent we propose the construction of MATHUSLA (MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles) [1], a dedicated large-volume displaced vertex detector (DV) for the HL-LHC on the surface above ATLAS or CMS. [...]

Long-Lived Particles at the Energy Frontier: The MATHUSLA Physics Case
/ Curtin, David (Toronto U.) ; Drewes, Marco (Louvain U., CP3) ; McCullough, Matthew (CERN) ; Meade, Patrick (YITP, Stony Brook) ; Mohapatra, Rabindra N. (Maryland U.) ; Shelton, Jessie (Illinois U., Urbana) ; Shuve, Brian (Harvey Mudd Coll. ; SLAC) ; Accomando, Elena (Southampton U.) ; Alpigiani, Cristiano (Washington U., Seattle) ; Antusch, Stefan (Basel U.) et al.
We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are a common prediction of a wide range of theories that address unsolved fundamental mysteries such as naturalness, dark matter, baryogenesis and neutrino masses, and represent a natural and generic possibility for physics beyond the SM (BSM).

The AEgIS Experiment
/ Knecht, A (CERN) ; Aghion, S (Milan Polytechnic) ; Ahlen, O (CERN) ; Amsler, C (Bern U., LHEP) ; Ariga, A (Bern U., LHEP) ; Ariga, T (Bern U., LHEP) ; Belov, A S (Moscow, INR) ; Bonomi, G (INFM, Brescia ; INFN, Pavia) ; Bräunig, P (Kirchhoff Inst. Phys.) ; Bremer, J (CERN) et al.
The AEgIS experiment aims at performing the first test of the Weak Equivalence Principle of General Relativity in the antimatter sector by measuring the gravitational acceleration acting on a beam of cold antihydrogen to a precision of 1%. The installation of the apparatus is making good progress and large parts were taken into operation. [...]

Measuring the gravitational free-fall of antihydrogen

Phys.) ; Bremer, J (CERN) et al.
Antihydrogen holds the promise to test, for the first time, the universality of free-fall with a system composed entirely of antiparticles. The AEgIS experiment at CERN’s antiproton decelerator aims to measure the gravitational interaction between matter and antimatter by measuring the deflection of a beam of antihydrogen in the Earths gravitational field ( $\overline {\textrm {g}}$ ).

Development of nuclear emulsions operating in vacuum for the AEgIS experiment

Phys.) et al.
/AEgIS
For the first time the AEgIS (Antihydrogen Experiment: Gravity, Interferometry, Spectroscopy) experiment will measure the Earth's local gravitational acceleration g on antimatter through the evaluation of the vertical displacement of an antihydrogen horizontal beam. This will be a model independent test of the Weak Equivalence Principle at the base of the general relativity. [...]

Comparison of Planar and 3D Silicon Pixel Sensors Used for Detection of Low Energy Antiprotons

The principal aim of the AEgIS experiment at CERN is to measure the acceleration of antihydrogen due to Earth's gravitational field. This would be a test of the Weak Equivalence Principle, which states that all bodies fall with the same acceleration independently of their mass and composition. [...]
