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.

LHC Searches for Long-Lived BSM Particles: Theory Meets Experiment

Thursday, November 12, 2015 - 9:00am to Saturday, November 14, 2015 - 2:00pm

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

New long-lived particles are predicted in many beyond the standard model theories. They have been extensively searched for in collider data, most recently in Run 1 of the LHC. As the community prepares for Run 2 analysis, there is a need to examine the previous searches, identify weak or uncovered areas, and develop a coherent strategy targeting all possible scenarios. The goal of the workshop is to bring experimentalists and theorists together to discuss these issues and help improve the coverage, flexibility, and future utility of LHC searches for long-lived particles, to ensure that potential long-lived BSM particles do not escape detection at the LHC.

Neutrino Mass: From the Terrestrial Laboratory to the Cosmos

Monday, December 14, 2015 - 9:00am to Wednesday, December 16, 2015 - 2:00pm

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

The goal of the workshop is to bring together a small group of theorists, experimentalists, and observers to address the relative implications of terrestrial, astrophysical, and cosmological probes of neutrino mass. With the prospect of order of magnitude improvements in the sensitivities of kinematic mass determinations, two-order of magnitude improvements in the lifetime sensitivity of neutrinoless double beta-decay searches, and significant advances in determinations of the sum of neutrino masses from large scale structure and the CMB, it is timely to delineate what a comparison of results from these, other laboratory and cosmological probes, and simulations might imply.
