The contribution to precision electroweak measurements due to TeV physics which couples primarily to the $W^\pm$ and $Z$ bosons may be parameterized in terms of the three `oblique correction' parameters, S, T and U. We extend this parameterization to physics at much lower energies, $\ge 100$ GeV, and show that in this more general case three more parameters are required (which we call V, W and X). Only two of these appear in neutral-current experiments, while the third new parameter enters into the $W^\pm$ width.

  1. Precision Electroweak Constraints on Neutrinophilic Scalars

    hep-ph 2026-06 unverdicted novelty 7.0

    Electroweak precision data constrain neutrinophilic scalar couplings to neutrinos via charged-current corrections, with the result holding in a UV-complete model for wide parameter ranges.

  2. Complementary Probes of Light Higgsinos: Electroweak Precision Measurements and Dark Matter Direct Detection

    hep-ph 2026-06 unverdicted novelty 5.0

    Future electroweak precision measurements can probe light higgsinos up to 500 GeV even in compressed spectra below the neutrino fog, complementing direct detection which reaches the 1 TeV thermal relic mass.

  3. Search for pair production of additional neutral scalars within the Inert Doublet Model in a final state with two electrons or two muons in proton-proton collisions at $\sqrt{s}$ = 13 TeV and 13.6 TeV

    hep-ex 2026-05 accept novelty 5.0

    No significant excess found; new exclusion limits reach m_H = 108 GeV for m_H - m_A = 78 GeV in the Inert Doublet Model.

  4. Probing the Inert Doublet Dark Matter with Stellar-Mass Black Hole Mini-Spikes

    hep-ph 2026-05 unverdicted novelty 5.0

    Fermi LAT data on mini-spikes around stellar-mass black holes rules out substantial regions of Inert Doublet Model dark matter parameter space, especially at multi-TeV masses.

  5. $S, T, U$ Parameters in The B-LSSM

    hep-ph 2025-01 unverdicted novelty 5.0

    S, T, U parameters are redefined for the B-LSSM using pinch technique contributions to gauge boson self-energies and expressed as functions of B-LSSM parameters, with experimental constraints applied.
