Abstract The Forward Physics Facility (FPF) is a proposal to create a cavern with the space
and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider …

High-energy cosmic rays are observed indirectly by detecting the extensive air showers
initiated in Earth's atmosphere. The interpretation of these observations relies on accurate …

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large
number of particles along the beam collision axis, outside of the acceptance of existing LHC …

The present white paper is submitted as part of the “Snowmass” process to help inform the
long-term plans of the United States Department of Energy and the National Science …

This Letter presents a measurement of the inelastic proton-proton cross section using 60 μ b-
1 of pp collisions at a center-of-mass energy s of 13 TeV with the ATLAS detector at the LHC …

We present the results of an improved Monte Carlo Glauber (MCG) model of relevance for
collisions involving nuclei at center-of-mass energies of the BNL Relativistic Heavy Ion …

We present a new version of the hadron interaction event generator sibyll. While the core
ideas of the model have been preserved, the new version handles the production of baryon …

We review open questions and prospects for progress in ultrahigh-energy cosmic ray
(UHECR) research, based on a series of discussions that took place during the “The High …

We report a study of the distributions of the depth of maximum, X max, of extensive air-
shower profiles with energies above 1 0 17.8 eV as observed with the fluorescence …

The TOTEM collaboration has measured the proton–proton total cross section at s= 13~ TeV
s= 13 TeV with a luminosity-independent method. Using dedicated β^*= 90~ m β∗= 90 m …
