We review and revise the phenomenology of the scalar portal -- a new scalar particle with the mass in GeV range that mixes with the Higgs boson. In particular, we consider production channels $B\to S K_1(1270)$ and $B\to S K_0^*(700)$ and show that their contribution is significant. We extend the previous analysis by comparing the production of scalars from decays of mesons, of the Higgs bosons and direct production via proton bremsstrahlung, deep inelastic scattering and coherent scattering on nuclei. Relative efficiency of the production channels depends on the energy of the beam and we consider the energies of DUNE, SHiP and LHC-based experiments. We present our results in the form directly suitable for calculations of experimental sensitivities.

  1. On Exclusive Coherent Production of Bosons in Electron-Proton Collisions

    hep-ph 2026-04 unverdicted novelty 6.0

    A phenomenological 2-to-3 framework is constructed for exclusive boson electroproduction that matches flux-factorized predictions near Q^{2}=0 while capturing finite-Q^{2} effects at larger virtualities.

  2. Detector performance at SHiP for cascade-produced long-lived particles

    hep-ph 2026-06 unverdicted novelty 5.0

    Cascade LLPs in SHiP suffer strong acceptance suppression, yielding at most moderate enhancement over primary production for light ALPs and subdominant contribution for HNLs from secondary kaons.

  3. Long-lived sterile neutrinos from axionlike particles at the Super Tau-Charm Facility

    hep-ph 2026-05 conditional novelty 5.0

    A proposed Chinese charm factory could detect heavy neutral leptons from axionlike-particle decays with a displaced-vertex search, reaching electron-neutrino mixing one to two orders of magnitude below current bounds.

  4. Can LLP detectors probe the reheating temperature? A case study of vector dark matter

    hep-ph 2026-04 unverdicted novelty 5.0

    In a vector dark matter extension of the Higgs portal, far detectors at colliders can probe otherwise inaccessible parameter space and set novel bounds on the reheating temperature.

  5. Probing the dark axion portal via $J/\psi$ decays at BESIII and STCF

    hep-ph 2026-06 unverdicted novelty 4.0

    Monte Carlo studies show BESIII data already reaches previously unexplored regions of the dark axion portal via J/ψ → a γ' decays, with STCF projected to improve sensitivity by about an order of magnitude.

  6. Long-lived sterile neutrinos from axionlike particles at the Super Tau-Charm Facility

    hep-ph 2026-05 unverdicted novelty 4.0

    STCF can reach |V_eN|^2 values one to two orders of magnitude below current bounds for heavy neutral leptons via displaced-vertex searches from ALP decays in D-meson production.
