We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

We present results for the isovector axial, scalar, and tensor charges g A ud, g S ud, and g T
ud of the nucleon needed to probe the Standard Model and novel physics. The axial charge …

The electroweak interaction in the standard model is described by a pure vector-axial-vector
structure, though any Lorentz-invariant component could contribute. In this Letter, we …

The current most stringent constraints on exotic scalar or tensor couplings in neutron and
nuclear β decay, involving left-handed neutrinos, are obtained from the Fierz interference …

Precision measurements of free-neutron β decay have been used to precisely constrain our
understanding of the weak interaction. However, the neutron Fierz interference term bn …

A reaction microscope (ReMi) has been combined with a magneto-optical trap (MOT) for the
kinematically complete investigation of atomic break-up processes. With the novel MOTReMi …

We have developed a position response calibration method for a micro-channel plate (MCP)
detector with a delay-line anode position readout scheme. Using an in situ calibration mask …

We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

CP violation is an important condition to explain the preponderance of baryons in our
universe, yet the available CP violation in the Standard Model (SM) via the so-called …

Precision measurements of the beta− neutrino angular correlation in nuclear beta-decay
provide a unique window into the physics beyond the Standard model. The WITCH (Weak …
