TL;DR: The results show that precision parity-violating measurements enable searches for physics beyond the standard model that can compete with direct searches at high-energy accelerators and, together with astronomical observations, can provide fertile approaches to probing higher mass scales.

TL;DR: In this article, a large set of cross sections for semi-inclusive electroproduction of charged pions (π±) from both proton and deuteron targets was measured, showing the onset of quark-hadron duality in this process, and the relation of this phenomenon to the high-energy factorization ansatz of electron-quark scattering and subsequent quark→pion production mechanisms.
