Lederle Graduate Research Tower (LGRT) 419B, UMass Amherst
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. Among the questions to be addressed are:
1. What are the implications of BSM scenarios that address the hierarchy problem(s) for the EW phase transition?
2. What BSM scenarios could lead to a first order EW phase transition as needed for electroweak baryogenesis?
3. What are the signatures at a next generation pp collider of these scenarios and how are they related to the character of the EW phase transition?
4. To what extend might these scenarios be probed with a next generation hadronic collider and would such studies complement those
anticipated at the LHC and future e+e- colliders?
