“…We note an existing experimental anomaly with respect to the SM for neutrino-nucleon scattering at the Q ∼ GeV c −1 scale (32). The current uncertainty from CEvNS measurements is at the ∼10% level at stopped-pion Q values of a few tens of MeV c −1 ; this is not currently competitive with other methods for determining θW at low Q from parity-violating electron-proton scattering (33), Moller scattering (34) and atomic parity violation (35). However, none of these experiments probe BSM physics that is specific to interactions of neutrinos and quarks, which would manifest as an inferred value of θW differing from the nominal SM expectation.…”

The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory provides an intense, high-quality source of neutrinos from pion decay at rest. This source was recently used for the first measurements of coherent elastic neutrino-nucleus scattering (CEvNS) by the COHERENT collaboration, resulting in new constraints of beyond-thestandard-model physics. The SNS neutrino source will enable further CEvNS measurements, exploration of inelastic neutrino-nucleus interactions of particular relevance for understanding of supernova neutrinos, and searches for accelerator-produced sub-GeV dark matter. Taking advantage of this unique facility, COHERENT's suite of detectors in "Neutrino Alley" at the SNS is accumulating more data to address a broad physics program at the intersection of particle physics, nuclear physics, and astrophysics. This review describes COHERENT's first two CEvNS measurements, their interpretation, and the potential of a future physics program at the SNS.

“…Note that values of |g 11 i | above the black band produce a |∆a e | that is too large and are thus excluded by the measurement; we refer to the text for further discussion. We also show the excluded region at 90% CL from the measurement of parity-violating Møller scattering from the E158 [82] experiment (solid boundary), as well as the excluded region anticipated from the expected sensitivity of the planned MOLLER experiment (dashed boundary) at Jefferson Laboratory [83,84], if no departure from the SM is observed. Constraints on the lightest M X i masses can come from the measured running of α(s); please see Sec.…”

“…The parity-violating asymmetry A PV in the low-momentum-transfer scattering of longitudinally polarized electrons from unpolarized electrons has been measured to a precision of 17 ppb in the E158 experiment at SLAC, yielding a determination of the value of the effective weak mixing angle sin 2 θ eff W to 0.5% precision [82]. In contrast, in a future experiment planned at the Jefferson Laboratory [83,84], the MOLLER collaboration expects to measure A PV to an overall precision of 0.7 ppb [84], to determine sin 2 θ eff W to 0.1% precision [84], with a commensurate improvement of A PV as a test of new physics. The determination of the weak mixing angle relies on the theoretical assessment of A PV in the SM [85][86][87][88][89][90], for which electroweak radiative corrections are important [86][87][88][89][90].…”

Scalars that carry lepton number can help mediate would-be lepton-number-violating processes, such as neutrinoless double β decay or lepton-scattering-mediated nucleon-antinucleon conversion.Here we show that such new scalars can also solve the anomaly in precision determinations of the fine-structure constant α from atom interferometry and from the electron's anomalous magnetic moment, a e ≡ (g − 2) e /2, by reducing |a e |. Study of the phenomenological constraints on these solutions favor a doubly-charged scalar with mass below the GeV scale. Significant constraints arise from the measurement of the parity-violating asymmetry in Møller scattering, and we consider the implications of the next-generation MOLLER experiment at Jefferson Laboratory and of an improved a e measurement.
