abstract

We carry out high-precision calculation of parity violation in cesium atom, reducing theoretical uncertainty by a factor of two compared to previous evaluations. We combine previous measurements with our calculations and extract the weak charge of the 133Cs nucleus, Q_W = -73.16(29)_exp(20)_th. The result is in agreement with the Standard Model (SM) of elementary particles. This is the most accurate to-date test of the low-energy electroweak sector of the SM. In combination with the results of high-energy collider experiments, we confirm the energy-dependence (or "running") of the electroweak force over an energy range spanning four orders of magnitude (from ~10 MeV to ~100 GeV). Additionally, our result places constraints on a variety of new physics scenarios beyond the SM. In particular, we increase the lower limit on the masses of extra $Z$-bosons predicted by models of grand unification and string theories.

  1. The X17 Existence Hinted at by Nuclear Reactor Neutrinos

    hep-ph 2026-05 unverdicted novelty 6.0 of 10

    Reactor neutrino data from CONUS+ and Dresden-II combined with COHERENT and IceCube data singles out a region of neutrino and nuclear couplings consistent with the X17 particle.

  2. Flavor specific chiral $U(1)_X$ framework for explaining the ATOMKI anomaly

    hep-ph 2026-04 unverdicted novelty 6.0 of 10

    A gauged, flavor-specific U(1)_X two-Higgs-doublet model can realize the axial-vector Z' couplings needed to explain the ATOMKI 8Be and 4He anomalies while evading current bounds.

  3. The X17 with Chiral Couplings

    hep-ph 2026-02 conditional novelty 6.0 of 10

    A spin-1 X17 with chiral couplings fits the ATOMKI nuclear anomalies at 99% CL only in a parameter region that atomic parity violation and KLOE-2/NA64 exclude, driven mainly by the 12C(17.23) transition.
