Seminars & Workshops

The ACFI hosts a weekly seminar series that brings researchers from around the world to present forefront research and interact with ACFI faculty, staff, and students. Informal research presentations by UMass Amherst and visitors take place in the weekly Fundamental Interactions Informal Talk.

The aim of ACFI topical workshops is to provide an opportunity for researchers from around the world to interact in a focused, short-term context to address an important open problem in the Energy, Intensity, or Cosmic frontiers as well as at their intersection. The general scope of the topical workshop is 10-20 participants who meet over a 2-5 day period at UMass Amherst, focusing on a specific problem, and formulating a plan for on-going research at the workshop conclusion.

The ACFI welcomes proposals for a topical workshop, which will be considered on a rolling basis. To submit a proposal, please contact the Director. A list of past workshops and meetings is also available.

Given that neutrino mass is so far the only laboratory evidence for physics beyond the Standard Model, understanding its origin could provide a key to unlock the secrets of the new physics. In the LHC era and in anticipation of exciting developments of future colliders, it is timely to discuss how effectively the neutrino mass physics could be probed at the high energy frontier. The workshop will bring together theorists and experimentalists to develop a roadmap for neutrino physics at the high energy frontier. The complementarity with the low-energy experiments at the intensity frontier, as well as the implications for other outstanding puzzles such as the matter-antimatter asymmetry and dark matter, will also be touched upon.

The gamma-boson exchange diagram plays an important role in a number of different areas of nuclear and particle physics. Two-photon exchange in elastic lepton-nucleon scattering is believed to become large at high momentum transfers to explain a large discrepancy in the proton elastic form factor determination. The gamma-Z box diagram is a significant contribution to the asymmetry in parity-violating electron scattering. Finally, the gamma-W diagram enters into beta-decays which are used to constrain fundamental elements of the Standard Model. The purpose of the workshop is to bring together both theorists and experimentalists in these different areas to improve our understanding of this important process.
