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.

Lambda and quasi-Lambda

ACFI Workshop
April 10-12, 2014 at UMass Amherst

De Sitter and Anti-deSitter provide simple, yet rich, playgrounds for studying quantum gravity and quantum field theory. On the observational side, Planck has provided a data set with unprecedented accuracy concerning (what we believe to be) a primordial epoch of quasi-de Sitter expansion. The goal of the workshop will be to study what data can teach us about the fundamental properties of exact (anti) de Sitter spaces.

Unlocking the Higgs Portal

Thursday, May 1, 2014 - 9:00am to Saturday, May 3, 2014 - 5:00pm
Lederle Graduate Research Tower (LGRT) 419B , UMass Amherst

Higgs portal interactions can address two open problems in cosmology: dark matter and the baryon asymmetry. In anticipation of the 14 TeV phase of the LHC and the development of a future electron-positron collider, it is timely to delineate the most important scenarios, to identify their LHC and lepton collider signatures, and to determine the extent to which collider searches may probe Higgs portal scenarios in the cosmologically relevant regions of parameter space.
