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.

Beta Decay as a Probe of New Physics

Thursday, November 1, 2018 - 9:00am to Saturday, November 3, 2018 - 1:00pm


This workshop will address the following questions: Which experimental approaches provide the most promising probes for new physics via neutron and nuclear beta decays? What theoretical input is required to ensure experiments achieve optimal sensitivity? We hope to provide a road-map for progress on the theory of nuclear decays and the beyond standard model scenarios they test to ensure the maximum impact for ongoing and planned experiments.

A central focus will be the evaluation of the beta energy dependence of decay observables, including the total decay spectrum, and and angular correlations, where new techniques promise, in principle, sensitivity below the 0.1% level, but will also assess the role of ongoing integral angular correlation work in neutrons and nuclei. Through dialog involving theorists and experimentalists, we expect to identify critical theory needs and the resources to address the identified problems. Some attention to important BSM scenarios and how to develop these in light of the results from the LHC will also be addressed. We plan to produce a white paper describing the most promising experiments, the theoretical issues which must be addressed, and the resources required to address them.
