“…The full calculation of all the Todd gluon TMDs, including the d-type ones is underway. They can serve as a useful guidance to shed light on gluon-TMD dynamics at new-generation particle colliders and experiments, such as the Electron-Ion Collider (EIC) [52], NICA-SPD [53], the High-Luminosity Large Hadron Collider (HL-LHC) [54], and the Forward Physics Facility (FPF) [55].…”

We present exploratory studies of the 3D proton tomography through polarized T -odd gluon TMDs at leading twist, obtained in a spectator-model framework. We embody in our approach a flexible parameterization for the spectator-mass spectral function, suited to catch both small-and moderate-x effects. All these studies are relevant to unveil the gluon dynamics inside hadrons, which represents a core research line of studies at new-generation colliders, such as the Electron-Ion Collider, NICA-SPD, the High-Luminosity LHC, and the Forward Physics Facility.

“…With a target mass of about 1.2 tons and an anticipated luminosity of 150 fb −1 a total of O(10 4 ) muon neutrino and O(10 3 ) electron neutrino interactions are expected to be observed. During the HL-LHC, additional far-forward neutrino experiments have been proposed in the context of the FPF [18]. In particular, this includes an emulsion based neutrino detector with target mass of about 20 tons called FASERν2, a liquid argon based neutrino detector with target mass of about 10 tons called FLArE and an electronic neutrino detector called AdvSND.…”

“…Assuming that the observed enhancement of strangeness production in high-energy hadronic collisions is at the core of the muon puzzle in this paper we study the concomitant π ↔ K swap impact on the development of extensive air showers (EASs), using phenomenological toy models implemented in AIRES (version 19.04.08) [15]. After that, we discuss the prospects to constrain our model using forward neutrino flux measurements at FASERν [16,17] and future experiments at the Forward Physics Facility (FPF) [18].…”

We investigate the observed muon deficit in air shower simulations when compared to ultrahighenergy cosmic ray (UHECR) data. Based upon the observed enhancement of strangeness production in high-energy hadronic collisions reported by the ALICE Collaboration, the concomitant π ↔ K swap is considered as the keystone to resolve the muon anomaly through its corresponding impact on the shower development. We construct a toy model in terms of the π ↔ K swapping probability F s . We present a parametrization of F s in terms of the pseudorapidity that can accommodate the UHECR data. Looking to the future, we explore potential strategies for model improvement using the massive amounts of data to be collected by LHC neutrino detectors, such as FASERν and experiments at the Forward Physics Facility. We calculate the corresponding sensitivity to F s and show that these experiments will be able to probe the model phase space.

“…A reliable determination of nPDFs is also critical in various astrophysical processes, for instance to make theoretical predictions of signal [8][9][10][11] and background [12][13][14] events in neutrino-nucleus scattering as measured at high-energy neutrino observatories such as IceCube [15] and KM3NeT [16]. In the longer term, nPDFs will be probed at the Electron Ion Collider (EIC) [17][18][19], by means of GeV-scale lepton scattering on light and heavy nuclei, and further tested at the proposed Forward Physics Facility (FPF) [20], by means of TeV-scale neutrino scattering on heavy nuclear targets.…”

We present an updated determination of nuclear parton distributions (nPDFs) from a global NLO QCD analysis of hard processes in fixed-target lepton-nucleus and proton-nucleus together with collider protonnucleus experiments. In addition to neutral-and charged-current deep-inelastic and Drell-Yan measurements on nuclear targets, we consider the information provided by the production of electroweak gauge bosons, isolated photons, jet pairs, and charmed mesons in proton-lead collisions at the LHC across centre-ofmass energies of 5.02 TeV (Run I) and 8.16 TeV (Run II). For the first time in a global nPDF analysis, the constraints from these various processes are accounted for both in the nuclear PDFs and in the freeproton PDF baseline. The extensive dataset underlying the nNNPDF3.0 determination, combined with its model-independent parametrisation, reveals strong evidence for nuclear-induced modifications of the partonic structure of heavy nuclei, specifically for the small-x shadowing of gluons and sea quarks, as well as the large-x anti-shadowing of gluons. As a representative phenomenological application, we provide predictions for ultra-high-energy neutrino-nucleon cross-sections, relevant for data interpretation at neutrino observatories. Our results provide key input for ongoing and future experimental programs, from that of heavy-ion collisions in controlled collider environments to the study of high-energy astrophysical processes.
