Physics with high-luminosity proton-nucleus collisions at the LHC

D. d'Enterria, C. A. Flett, I. Grabowska-Bold +29

The physics case for the operation of high-luminosity proton-nucleus ( $p A$ ) collisions during Run 3 and 4 at the LHC is reviewed. The collection of $O$ (1-10 pb $^{- 1}$ ) of…

Heavy quark mass effects in charged-current deep-inelastic scattering at approximate NNLO in the Aivazis-Collins-Olness-Tung scheme

Peter Risse, Valerio Bertone, Tomas Ježo +4

The approximate SACOT- $χ$ scheme for heavy quark production in deep-inelastic scattering was initially formulated for the neutral current structure functions $F_{2}$ and $F_{L}$ . We ex…

Quantum Information meets High-Energy Physics: Input to the update of the European Strategy for Particle Physics

Yoav Afik, Federica Fabbri, Matthew Low +68

Some of the most astonishing and prominent properties of Quantum Mechanics, such as entanglement and Bell nonlocality, have only been studied extensively in dedicated low-energy la…

Reinterpretation and preservation of data and analyses in HEP

Jon Butterworth, Sabine Kraml, Harrison Prosper +145

Data from particle physics experiments are unique and are often the result of a very large investment of resources. Given the potential scientific impact of these data, which goes…

Constraints on asymmetric production of long-lived scalars at the Large Hadron Collider

Thomas Chehab, Louie Dartmoor Corpe, Andreas Goudelis +2

Searches for pair-produced long-lived particles (LLPs) at the LHC commonly operate under the assumption that the two LLPs are identical. In this paper we entertain the possibility…

Baryonic Axion in neutron-antineutron oscillation

Théo Brugeat

The accidental baryonic symmetry is expected to be broken and required from the observed matter-antimatter asymmetry. The neutron-antineutron oscillating system is the hallmark of…

The strong CP puzzle and axions

Christopher Smith

In the first part of this talk, after a brief presentation of the strong CP puzzle, the construction of axion models and their main phenomenological features are described. In the…
