A new paper studies the Sivers asymmetry in semi-inclusive deep-inelastic hadron production, in particular, the photon-gluon fusion channel, where three-gluon correlation functions play a major role within the twist-3 collinear factorization formalism. The work establishes the correspondence between the formalism with three-gluon correlation functions and the usual transverse momentum dependent (TMD) factorization formalism at moderate hadron transverse momenta. The QCD collinear evolution equations of the twist-3 Qiu-Sterman function are also derived.

Colloquium: The Pursuit of Better SRF Cavities
Join Charlie Reece as he describes the superconducting niobium rf cavities that provide a remarkably efficient way to accelerate charged particles, especially for continuous wave applications. He’ll explain how practical cost pressures continue to motivate development of ever more energy efficient and lower capital cost systems and discuss the push to realize reliably SRF cavity surfaces with very low surface resistance with maximally high surface fields. He'll also address recent developments, including a collaborative effort involving Jefferson Lab, Fermilab, Cornell University, and The Helmholtz-Zentrum Berlin for Materials and Energy, as well as the LCLS-II project that will exploit new developments to minimize cryogenic capital and operating costs. These new understandings and associated challenges will be reviewed in their historical international and Jefferson Lab context. The colloquium will be held in the CEBAF Center auditorium on Oct. 22 at 3 p.m.
