(CERN) ; Albrow, M.G. (Fermilab) ; Berryhill, J. (Fermilab) ; Green, D.R. (Fermilab) ; Hirschauer, J. (Fermilab) et al.
We describe a proposal to add a set of very forward detectors to the CMS experiment for the high-luminosity era of the Large Hadron Collider to search for beyond the standard model long-lived particles, such as dark photons, heavy neutral leptons, axion-like particles, and dark Higgs bosons. The proposed subsystem is called FACET for Forward-Aperture CMS ExTension, and will be sensitive to any particles that can penetrate at least 50 m of magnetized iron and decay in an 18 m long, 1 m diameter vacuum pipe.

An Update to the Letter of Intent for MATHUSLA: Search for Long-Lived Particles at the HL-LHC

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 (LoI), see CDS:LHCC-I-031, arXiv:1811.00927. [...]

Further studies on the physics potential of an experiment using LHC neutrinos

Bologna, DIFA) ; Danzeca, S. (CERN) ; De Roeck, A. (CERN) ; De Rújula, A. (Madrid, Inst. Estructura Materia) ; Fasanella, D. (CERN) et al.
We discuss an experiment to investigate neutrino physics at the LHC in Run 3, with emphasis on tau flavour. As described in our previous paper [arXiv:1903.06564v1], the detector can be installed in the decommissioned TI18 tunnel, about 480 m downstream the ATLAS cavern, after the first bending dipoles of the LHC arc.

The MATHUSLA Test Stand

The rate of muons from LHC $pp$ collisions reaching the surface above the ATLAS interaction point is measured and compared with expected rates from decays of $W$ and $Z$ bosons and $b$- and $c$-quark jets. In addition, data collected during periods without beams circulating in the LHC provide a measurement of the background from cosmic ray inelastic backscattering that is compared to simulation predictions.

We discuss an experiment to investigate neutrino physics at the LHC in Run 3, with emphasis on tau flavour. As described in our previous paper [1], the detector can be installed in the decommissioned TI18 tunnel, ≈480 m downstream the ATLAS cavern, after the first bending dipoles of the LHC arc. [...]

XSEN: a νN Cross Section Measurement using High Energy Neutrinos from pp collisions at the LHC
/ Beni, N ; Buontempo, S ; Camporesi, T ; Cerutti, F ; Dallavalle, G M ; De Lellis, G ; De Roeck, A ; DeRújula, A ; DiCrescenzo, A ; Fasanella, D et al.
XSEN (Cross Section of Energetic Neutrinos) is a small experiment designed to study, for the first time, neutrino-nucleon interactions (including the tau flavour) in the 0.5-1 TeV neutrino energy range. [...]

Production of neutrinos is abundant at LHC.
Flavour composition and energy reach of the neutrino flux from proton-proton collisions depend on the pseudorapidity $\eta$. [...]

First beam tests of prototype silicon modules for the CMS High Granularity Endcap Calorimeter
/ Akchurin, N (Texas Tech.) ; Apreysan, A (Fermilab) ; Banerjee, S (Fermilab) ; Barney, D (CERN) ; Bilki, B (Iowa U.) ; Bornheim, A (Caltech) ; Bueghly, J (Northwestern U.) ; Callier, S (Ec. Polytech., OMEGA) ; Candelise, V (Taiwan, Natl. Central U.) ; Chang, Y H (Taiwan, Natl. Central U.) et al.
The High Luminosity phase of the Large Hadron Collider will deliver 10 times more integrated luminosity than the existing collider, posing significant challenges for radiation tolerance and event pileup on detectors, especially for forward calorimetry. As part of its upgrade program, the Compact Muon Solenoid collaboration is designing a high-granularity calorimeter (HGCAL) to replace the existing endcap calorimeters. [...]
