“…This will be not only the first ever measurement of neutrino production at a collider, but it will also involve an energy range where the production cross sections are not currently constrained. A first result obtained from a pilot run in 2018 with a reduced version of the detector was recently published, leading to six neutrino candidates produced in p-p collisions at √ s = 13 TeV for an integrated luminosity of 12.2 fb −1 [2].…”

The LHC Run III will be a crucial run for the two LHC forward experiments: LHCf and FASER. In particular, Run III will be the last run where the LHCf detector can operate and, at the same time, the first run of the new FASER project. The LHCf experiment is dedicated to precise measurements of forward production, necessary to tune hadronic interaction models employed in cosmic-ray physics. In Run III, the experiment will accomplish two fundamental goals: operating in p-p collisions at √ s = 14 TeV, it will acquire a ten times larger statistics respect to Run II, in order to have precise measurements of π 0 production; operating in high energy p-O and O-O collisions, it will measure forward production in a configuration that is very similar to the first interaction of an Ultra High Energy Cosmic Ray with an atmospheric nucleus. The FASER experiment is dedicated to the search of new weakly-interacting light particles, thanks to a forward detector with proper shielding from Standard Model background. In Run III, the experiment will search for new particles with a good sensitivity, which can be strongly improved by a following possible upgrade before HL-LHC. In addition, thanks to the dedicated FASERν detector, the experiment will measure neutrino production at a collider for the first time. In this contribution, we discuss the main results expected from the LHCf and FASER experiments in Run III, highlighting their fundamental contribution in research fields that are not accessible to the four large LHC experiments.

“…Although the possibility of detecting and probing neutrinos at the LHC was considered as early as 1984 [1][2][3][4][5][6], no LHC neutrino has been detected for a long time. This situation changed very recently, when the FASER collaboration reported the observation of the first neutrino interaction candidates at the LHC [7]. This situation will further improve during the third run of the LHC with upcoming FASERν [8,9] and SND@LHC detectors [10,11].…”

With the upcoming Run 3 of the LHC, the FASERν and SND@LHC detectors will start a new era of neutrino physics using the far-forward high-energy neutrino beam produced in collisions at ATLAS. This emerging LHC neutrino physics program requires reliable estimates of the LHC's forward neutrino fluxes and their uncertainties. In this paper we provide a new fast-neutrino flux simulation, implemented as a RIVET module, to address this issue. We present the expected energy distributions going through the FASERν and SND@LHC detectors based on various commonly used event generators, analyze the origin of those neutrinos, and present the expected neutrino event rates.

“…These experiments exploit the large forward flux of pions and other SM particles, which, if they decay to new light particles, can create a large forward flux of LLPs and DM. The recent detection of TeV neutrino candidates in the forward region [1] also opens a new window on neutrinos at colliders, which may be used to probe both SM and beyond the SM (BSM) phenomena [2][3][4].…”

“…For the High Luminosity LHC (HL-LHC) era, detectors under consideration include upgrades of these detectors (FASER2, FASERν2, and Advanced SND), as well as the Forward Liquid Argon Experiment (FLArE) [7]. 1 A new facility, the Forward Physics Facility (FPF) [4,25], has been proposed to accommodate these experiments.…”

Models with light dark sector and dark matter particles motivate qualitatively new collider searches. Here we carry out a comprehensive study of hadrophilic models with U(1)B and U(1)B−3L τ gauge bosons coupled to light dark matter. The new mediator particles in these models couple to quarks, but have suppressed couplings to leptons, providing a useful foil to the well-studied dark photon models. We consider current bounds from accelerator and collider searches, rare anomalyinduced decays, neutrino non-standard interactions, and dark matter direct detection. Despite the many existing constraints, these models predict a range of new signatures that can be seen in current and near future experiments, including dark gauge boson decays to the hadronic final states π + π − π 0 , π 0 γ, K + K − , and KSKL in FASER at LHC Run 3, enhancements of ντ scattering rates in far-forward neutrino detectors, and thermal dark matter scattering in FLArE in the HL-LHC era. These models therefore motivate an array of different experiments in the far-forward region at the LHC, as could be accommodated in the proposed Forward Physics Facility.
