The Electroweak Box

Thursday, September 28, 2017 - 9:00am to Saturday, September 30, 2017 - 1:00pm


The gamma-boson exchange diagram plays an important role in a number of different areas of nuclear and particle physics. Two-photon exchange in elastic lepton-nucleon scattering is believed to become large at high momentum transfers to explain a large discrepancy in the proton elastic form factor determination. The gamma-Z box diagram is a significant contribution to the asymmetry in parity-violating electron scattering. Finally, the gamma-W diagram enters into beta-decays which are used to constrain fundamental elements of the Standard Model.

The purpose of the workshop is to bring together both theorists and experimentalists in these different areas to improve our understanding of this important process. An important focus will be on the interplay between the gamma-boson exchange contributions to different electroweak observables and the opportunities to exploit measurements to calibrate theoretical predictions. We hope to develop a roadmap for theory and experiment through a set of informal talks and discussions.
