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.

Measuring the Neutron Lifetime

Friday, September 19, 2014 - 9:00am to Sunday, September 21, 2014 - 12:00pm

Lederle Graduate Research Tower (LGRT) 419B, UMass Amherst

The neutron lifetime is an important parameter for a variety of studies in nuclear, particle, and astrophysics. At present, the measurements of the neutron lifetime with the lowest quoted errors are in serious disagreement. The workshop will address the issue of next generation neutron lifetime experiments with the goal of producing a roadmap for the production of a robust experimental determination.

Fundamental Symmetry Tests with Rare Isotopes

Thursday, October 23, 2014 - 5:00pm to Saturday, October 25, 2014 - 5:00pm

Joint ACFI-FRIB workshop

Atomic nuclei provide powerful laboratories for testing nature’s fundamental symmetries. With the larger number and quantity of isotopes that the Facility for Rare Isotope Beams (FRIB) will make available, new and improved tests, such as for atomic EDMs, will be possible. The workshop will assess the opportunities for fundamental symmetry tests that FRIB make possible and identify those most important to pursue.

Time-reversal Tests in Nuclear and Hadronic Processes

Thursday, November 6, 2014 - 8:45am to Saturday, November 8, 2014 - 5:00pm

Lederle Graduate Research Tower (LGRT) 419B, UMass Amherst

The workshop will address opportunities for tests of time-reversal invariance in neutron-nucleus interactions and weak decays as well as the related tests of C-invariance in rare eta decays. The program will focus on the relationship with tests of time-reversal invariance with electric dipole moment searches, methods for computing the hadronic and nuclear matrix elements, and experimental opportunities.
