Welcome! Our mission is to advance research in
theoretical and experimental physics at the interface
of the Energy, Intensity, and Cosmic frontiers.

We seek answers to key open questions about
nature’s fundamental interactions, such as:

Why is there more matter than anti-matter in the Universe?

What additional forces were active during the first moments after the Big Bang?

How are protons and neutrons put together?

We address these and other questions through international
topical workshops; a visiting researcher program;
UMass faculty, staff, and student research
as well as other activities.

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.
