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.

Testing CP-Violation for Baryogenesis

Thursday, March 29, 2018 - 9:00am to Saturday, March 31, 2018 - 1:00pm


Explaining the cosmic matter-antimatter asymmetry requires CP-violation beyond that of the Standard Model. Electric dipole moment searches and measurements of CP-violating observables in heavy quark systems place tight constraints on new CP-violation at and below the weak scale. Next generation EDM searches and heavy flavor probes, together with prospective collider tests, will have considerably greater sensitivities. This workshop will explore how these future probes of CP-violation may provide tests of scenarios proposed to explain the matter-antimatter asymmetry.
