Past Workshops & Meetings
Lederle Graduate Research Tower (LGRT) 419B, UMass Amherst
This workshop will cover a range of related topics, including resurgence and asymptotic analysis, phenomena in compactified gauge theories, path integral complexification, and others, in which considerable progress has been made in recent years. The purpose of this meeting is to bring together a group of experts and a group of more phenomenologically-oriented high-energy theorists in order to bring broader attention to the most interesting theoretical developments.

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.

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.

This will be the first in a series of workshops focusing on the physics opportunities with a next generation proton-proton collider.
The goal of the workshop is to identify the high energy collider signatures associated with different scenarios for the electroweak phase transition, focusing on opportunities for a next generation pp collider. Exploring the thermal history associated with electroweak symmetry breaking is a question at the forefront of particle physics and cosmology. In the Standard Model, EWSB is associated with a cross over transition. However, in a variety of well-motivated SM extensions, the nature of the EWSB transition may be different. Of particular interest is the possibility of a first order electroweak phase transition that would provide conditions needed for electroweak baryogenesis.
The format will involve a mixture of informal talks and discussions including both theorists and experimentalists. We anticipate that the workshop will lead to new dedicated studies to identify the physics reach of a ~ 100 TeV pp collider with respect to the electroweak phase transition.

A variety of extended Higgs sector models contain new sources of CP-violation that may have implications for the origin of the cosmic baryon asymmetry. The goal of the workshop is to identify the existing low-energy constraints on Higgs CP violation as well as the possible signatures at high-energy colliders. Given the imminent start of Run II at the LHC, the prospects of significantly more sensitive low-energy CPV probes, and developing plans for future lepton and hadron colliders, it is timely to explore in detail the best strategies for uncovering CP-violation in Higgs sector extensions.
