Welcome!

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.

Theoretical Innovations for Future Experiments Regarding Baryon Number Violation by Two Units I

Monday, August 3, 2020 - 9:00am to Thursday, August 6, 2020 - 5:00pm

ACFI Online

We hope to collectively orient the theoretical and phenomenological communities via an invitational forum, focusing on strategy for the forthcoming Snowmass process and influencing the proceeding, highly developmental years within the field in order to better serve the experimental community interested in baryon number violation (BNV), and more specifically, BNV by two units (ΔB=2), a B-L violating possibility. This looks forward to the application of theoretical ideas to the interpretation of future measurements made by the ESS NNBar Collaboration, DUNE, PNPI Gatchina, and Hyper-Kamiokande in the realm of dinucleon decay and neutron-antineutron transformations (n→n ̅). These ideas can be applied to existing and future theoretical and experimental studies, bolstering the community’s fundamental understanding of the topic.

QCD Real-Time Dynamics and Inverse Problems

Thursday, October 8, 2020 - 9:00am to Saturday, October 10, 2020 - 1:00pm

LGRT 419B

Realizing the full potential of experimental studies of nuclear matter requires a comprehensive understanding of the dynamics of its microscopic constituents, within the theory of quantum chromodynamics (QCD). Lattice QCD calculations have made significant contributions to our understanding of the strong interaction, but little is known from ab initio calculations about the dynamical properties of quarks and gluons. A central challenge for such calculations is the need to solve ill-posed inverse problems. This workshop will bring together practitioners in the field of lattice QCD and other communities working with inverse problems to address recent progress and remaining challenges in the extraction of dynamical properties from both numerical calculations and from experiment.
