The electroweak model operates with only a few fundamental parameters. Extracting them from high-precision measurements in various systems and at different kinematics requires computing quantum corrections (both universal and process-specific) to leading-order SM predictions with an adequate precision. Recent advances in computing process-specific electroweak box corrections led to...

The emergence of gravitational wave observatories provides an exquisite opportunity to probe the nuclear equation of state at a few times nuclear saturation density with mergers involving neutron stars. If nucleons possess interactions beyond those prescribed by the Standard Model, then these modify the equation of state – and thus macroscopic neutron star properties – in a way that may be...

The MUon Scattering Experiment (MUSE), which takes place at the PiM1 beamline of the Paul Scherrer Institut (PSI), aims to simultaneously measure elastic $ep$ and $\mu p$ scattering in order to determine the proton charge radius. However with the beamline and kinematics available to the experiment, MUSE has a broad physics reach. As the experiment uses both positively and negatively charged...

The isospin violating decay η → π+π−π0 is driven by the strong force and allows a probe of the light quark masses, via measurement of the corresponding decay amplitude. This amplitude is accessible either via a Dalitz plot or partial wave analysis. The latter... -

The Hall D Jefferson Lab Eta Factory (JEF) will collect 500 pb${^{-1}}$ of data between 8 and 12 GeV at incident photon-beam energies with the GlueX apparatus and an upgraded Forward Calorimeter. The JEF physics program addresses new physics and symmetry violation in hadron physics, including hadron decay dynamics. The search for sub-GeV dark particles will be performed in three different...
