  2. 49. The effect of forward charm production modelling on prompt neutrino flux estimates
    Atri Bhattacharya (University of Liège)

  3. 41. An explanation of the muon puzzle of ultrahigh-energy cosmic rays and the role of the Forward Physics Facility for model improvement
    Sergio Sciutto (Departamento de Fisica, Universidad Nacional de La Plata)

    We investigate the observed muon deficit in air-shower simulations when compared to ultrahigh-energy cosmic ray (UHECR) data. We assume that the enhancement of strangeness production in high-energy hadronic collisions reported by the ALICE Collaboration is the keystone to resolve the muon anomaly and study the concomitant $\pi \leftrightarrow K$ swap impact on the shower development. We...

  4. 47. Tuning Pythia for Forward Physics
    Max Fieg
    31/01/2022, 20:00

    The event generator, Pythia, has been invaluable in making predictions at colliders like the LHC. However, Pythia was tuned with central ($\eta$<5) measurements, and so it should not be expected to reproduce forward physics data, such as what the LHCf collaboration has obtained ($\eta$>10). If new physics is to be probed at the proposed FPF, one must sufficiently understand the incoming shower...

  5. 46. Freeze-in sterile neutrino dark matter in a class of U$(1)^\prime$ models with inverse seesaw
    Tanmay Poddar (Physical Research Laboratory)
    31/01/2022, 20:15

    We consider a general, anomaly free U$(1)^\prime$ extension of the Standard Model (SM) where the neutrino mass is generated at tree level from the inverse seesaw mechanism.
    After U$(1)^\prime$ symmetry breaking the mass of a neutral beyond the SM (BSM) gauge boson $(Z^\prime)$ is originated which can be produced it at high energy colliders.
    The model contains three generations of heavy...

  6. 6. Dark matter freeze-in from semi-production
    Maxim Laletin (NCBJ)
    31/01/2022, 20:30

    We study a novel dark matter production mechanism based on the freeze-in through semi-production, i.e. the inverse semi-annihilation processes. A peculiar feature of this scenario is that the production rate is suppressed by a small initial abundance of dark matter and consequently creating the observed abundance requires much larger coupling values than for the usual freeze-in. We provide a...

  7. 8. Searching for rich dark sectors in the FPF through secondary production and in indirect dark matter searches
    Krzysztof Jodlowski
    31/01/2022, 20:45

    Light new physics has become a particularly active research direction, in particular with the proposed dedicated Forward Physics Facility at CERN, as well as with the upcoming FASER detector measurements. In the talk, we will describe how the small lifetime regime of light long-lived particles in the non-minimal BSM scenarios based on renormalizable portals can be covered in the FPF using the...
