  8. 4. Cosmic Millicharge Background: Probing Reheating Cosmology, String Theory, and GUTs in FORMOSA & FPF
    Yu-Dai Tsai (University of California, Irvine)
    21/01/2025, 15:00

    We demonstrate that the searches for dark sector particles can provide probes of reheating scenarios, focusing on the cosmic millicharge background produced in the early universe. We discuss two types of millicharge particles (mCPs): either with, or without, an accompanying dark photon. These two types of mCPs have distinct theoretical motivations and cosmological signatures. We discuss...

  9. 31. Sweeper Magnet study
    Kohei Chinone (Chiba University (JP))
    21/01/2025, 15:00

    At the FPF site, the background muon levels are expected to be similar to those at the current FASERν site. While the FASERν experiment requires replacing the detector 2-3 times per year, we aim to reduce this to once per year for FASERν2. To achieve this, We studied possibilities to use a sweeper magnet to reduce the background muons to one-third.
    In this study, I performed GEANT4...

  10. 35. Dark photon pair production via off-shell dark Higgs at FASER
    Yohei Nakashima
    21/01/2025, 15:20

    We consider a dark photon model in which the dark U(1) gauge symmetry is spontaneously broken by a vacuum expectation value of a new scalar boson. We focus on the ForwArd Search ExpeRiment (FASER) and calculate its sensitivity to the dark photon produced from the off-shell decay of the new scalar boson. It is found that the off-shell production extends the sensitivity region beyond the...

  11. 9. Optical readout option for the FLArE detector
    k Mavrokoridis (University of Liverpool (GB))
    21/01/2025, 15:20

    I will present results obtained using the ARIADNE fast optical readout system and on how these inform the design of a FLArE optical LArTPC. A conceptual design of the FLArE TPC with a light readout plane and fast TimePix cameras will be discussed as well as a vacuum insulated cylindrical cryostat for this TPC option.

  12. 32. Dark Vector Splitting Functions in Proton Bremsstrahlung
    Saeid Foroughi-Abari
    21/01/2025, 15:40

    Experiments at the Forward Physics Facility are sensitive to new weakly coupled degrees of freedom across a broad mass range. Among the various production modes in proton-proton collisions, bremsstrahlung is particularly important for dark sector degrees of freedom with masses between 0.5 and 2.0 GeV, due to mixing with hadronic resonances. In this talk, I will revisit the calculation of dark...

  13. 6. Data-driven constraints on the prompt neutrino fluxes
    Jelle Koorn, Jukka John (Nikhef Theory Group)
    21/01/2025, 15:40

    The detection of TeV-energy neutrinos by the LHC far-forward detectors FASER/FASER$\nu$ and SND@LHC enables novel opportunities to validate theoretical predictions of of forward light particle production. In this work we present work in progress towards using the FASER and FPF event rate measurements to extract the LHC forward neutrino fluxes in a theory-agnostic manner by means of machine...

  14. 7. Discovering Light Scalars Beyond Minimal Flavor Violation
    Noam Burger
    21/01/2025, 16:00

    We study a simple class of flavored scalar models, in which the couplings of a new light scalar to standard-model fermions are controlled by the flavor symmetry responsible for fermion masses and mixings. The scalar couplings are then aligned with the Yukawa matrices, with small but nonzero flavor-violating entries. D-meson decays are an important source of scalar production in these models,...

  15. 3. Unravelling New Physics Signals at the HL-LHC with Low-Energy Constraints
    Elie Hammou
    21/01/2025, 16:00

    Recent studies suggest that global fits of Parton Distribution Functions (PDFs) might inadvertently 'fit away' signs of new physics in the high-energy tails of the distributions measured at the high luminosity programme of the LHC (HL-LHC). This could lead to spurious effects that might conceal key BSM signatures and hinder the success of indirect searches for new physics. In this talk, I...

  16. 36. Discovering neutrino tridents at FASER$\nu$2
    Dr Toni Makela (University of California, Irvine)
    21/01/2025, 16:50

    Neutrino trident production of di-lepton pairs is well recognized as a sensitive probe of both electroweak physics and physics beyond the Standard Model. Although a rare process, it could be significantly boosted by such new physics, and it also allows the electroweak theory to be tested in a new regime. We demonstrate that the forward neutrino physics program at the Large Hadron Collider...

    Josh McFayden (University of Sussex), Olivier Salin (Université Paris-Saclay)
    21/01/2025, 16:50

    This talk will aim to present and discuss the in-progress FASER-2 simulation and detector design performance document, which outlines the physics goals, detector requirements, simulation studies, and conceptual design scenarios for the proposed detector. The simulation framework developed uses Geant4 to describe detector geometry for sensitivity studies, along with the ACTS toolkit for track...

  18. 34. DELIGHT and FOREHUNT: dedicated detectors at FCC-hh for light long-lived particles
    Rhitaja Sengupta (BCTP and Physikalisches Institut der Universität Bonn, Germany)
    21/01/2025, 17:10

    Our efforts in searching for hints of new physics require close attention to the signatures of light particles arising in theories beyond the Standard Model (BSM) physics, as they could have eluded our searches. In many theories, these light BSM particles can have long lifetimes and are worth exploring. We focus on light long-lived particles (LLPs) coming from the decay of the discovered Higgs...

  19. 2. Tau polarization effects in $\nu_\tau / \bar{\nu}_\tau $ - tungsten interactions at the LHC energies
    Reinaldo Francener (Universidade Estadual de Campinas)
    21/01/2025, 17:10

    Considering that the study of neutrino - nucleus interactions with incident neutrino energy ranges in the GeV - TeV range is feasible at the Large Hadron Collider, we investigate in this work the degree of polarization ${\cal{P}}$ of the (anti) tau lepton produced in (anti) tau neutrino - tungsten interactions. In this study we also investigate the impact of the tau polarization on the pions...

    Dr Wenjie Wu (University of California, Irvine), Wenjie Wu (University of California, Irvine)
    21/01/2025, 17:30

    We discuss results from simulations and CNNs to distinguish neutrino CC and NC events with a scintillator bar-tungsten detector in the FASER location.

  21. 38. Unlocking the Inelastic Dark Matter Window with Vector Mediators
    Peter Reimitz
    21/01/2025, 17:30

    Despite the robust cosmological and astrophysical evidence confirming the existence of a non-baryonic matter component in the Universe, the underlying nature of Dark Matter (DM) remains a mystery. Among the several possible scenarios, light DM candidates thermally produced in the early Universe are especially interesting, since their abundance could be set via the standard freeze-out...

  22. 37. Exploring the LHC as a TeV Muon Beam Dump: Muonphilic Scalars at FASER
    Roshan Mammen Abraham (University of California Irvine (US))
    21/01/2025, 17:50

    At FASER, neutrinos are predominantly produced from meson decays, which also result in an intense energetic flux of muons in the forward direction, which are regularly observed by FASER. So far, these muons are treated only as backgrounds to neutrino and new physics studies, and extensive effort is required to suppress them. Here, we consider the opposite scenario and use muons produced in the...

  23. 5. FASERCal: High-Energy Neutrino Measurements at FASER
    Charlotte Cavanagh (ETH Zurich (CH))
    21/01/2025, 17:50

    To address the challenges of higher muon background in addition to the increase in luminosity in LHC Run 4, ETH Zurich proposes a novel detector system which aims to provide highly granular 3D tracking, calorimetry and muon identification with a design that is compact, modular and scalable. The proposed FASERCal detector is designed to detect both charged-current and neutral-current neutrino...
