“…Finally, we point out that the EIC will have at its disposal the ability to perform a number of more direct probes for BSM physics, including leptoquark searches for charged-lepton flavor violation (CLFV), as well as precise constraints to sin 2 θ W through parity-violating DIS measurements. In the case of sin 2 θ W measurements, the EIC would have significant constraining power over extensions of the EW sector, including scenarios involving the presence of hypothetical Z bosons [15] as represented in Fig. 4.…”

Deeply-inelastic scattering (DIS) stands to enter a golden age with the prospect of precision programs at the Electron-Ion Collider (EIC) and Large Hadron-electron Collider (LHeC). While these programs will be of considerable importance to resolving longstanding issues in (non)perturbative QCD as well as hadronic and nuclear structure, they will also have valuable implications for a wider range of physics at the Energy and Intensity Frontiers, including at the High-Luminosity LHC (HL-LHC) and future \nu AνA facilities. In this plenary contribution, we highlight a number of salient examples of the potential HEP impact from the complementary EIC and LHeC programs drawn from their respective Yellow Report and Whitepaper. Interested readers are encouraged to consult the extensive studies and literature from which these examples are taken for more detail.

“…These exciting prospects are a consequence of the designed high luminosity, relatively clean experimental environment in eA collisions, and the multipurpose detector design [3,4]. Indeed, there are unique processes beyond the SM for EIC to explore [5]. First, the precision determinations for the EW neutral current [6] and the weak mixing angle [5,7,8] will provide sensitive probes of new light neutral gauge boson interactions (Z ) [9][10][11][12].…”

The future Electron-Ion Collider (EIC) at Brookhaven National Laboratory, along with its primary capacity to elucidate the nuclear structure, will offer new opportunities to probe physics beyond the Standard Model coupled to the electroweak sector. Among the best motivated examples of such new physics are new heavy neutral leptons (HNLs), which are likely to play a key role in neutrino mass generation and lepton number violation. We study the capability of the EIC to search for HNLs, which can be produced in electronproton collisions through charged current interactions as a consequence of their mixing with light neutrinos. We find that, with the EIC design energy and integrated luminosity, one is able to probe HNLs in the mass range of 1 GeV−100 GeV with mixing angles down to the order of 10 −4 − 10 −3 through the prompt decay, and 10 −6 − 10 −4 via the displaced decay signatures. We also consider the invisible mode where an HNL is undetected or decaying to dark sector particles. One could potentially probe heavy HNLs for mixing angles in the window 10 −3 − 10 −2 , provided SM background systematics can be brought under control. These searches are complementary to other probes of HNLs, such as neutrino-less double-β decay, meson decay, fixed-target, and high-energy collider experiments.

“…Besides opening up a new QCD frontier, the EIC also offers an excellent chance to study precision electroweak (EW) physics and probe physics beyond the Standard Model (BSM) [3]. These opportunities are facilitated by the large integrated luminosity, clean experimental environment, and multi-purpose hermetic detector [2,4].…”

In this whitepaper, we consider the model of heavy neutral leptons (HNLs) as an example to explore the potential of new physics searches at the Electron-Ion Collider (EIC). We propose two broad categories of search strategies depending on the HNL lifetime: direct searches for the prompt decay of HNLs with a short lifetime and displaced vertex searches for long-lived ones. After identifying the most promising signals and the corresponding backgrounds, we perform a detailed simulation to estimate the sensitivity of the EIC to HNLs, accounting for detector thresholds, resolutions, and geometric acceptance. We derive projections for the EIC reach to the HNL squared mixing angle as a function of the HNL mass under the electron flavor mixing dominance hypothesis. Our findings indicate that the EIC can provide comparable sensitivity to the existing constraints for the prompt searches, while the displaced vertex searches can cover substantial new ground for HNLs in the 1-10 GeV mass range. Our proposed strategies are generally applicable to other new physics scenarios as well and motivate additional phenomenological exploration and dedicated future searches at the EIC.
