- Euclidean Wormholes: Conceptual Issues and Applications
- Time: 4:00 pm
- Place: Chamberlin 5280
- Speaker: Pablo Soler Gomis, CTPU - Institute for Basic Science
- Abstract: An important open question in the study of quantum gravity is whether topologically non trivial spacetime configurations (Euclidean wormholes) should be taken into account in the path integral. If present, they can generate phenomenologically relevant couplings and play an important role, e.g. in breaking axionic shift symmetries. At the same time, they pose deep conceptual problems such as the appearance of random couplings in the effective action or conflicts with holography. I will introduce in this talk some of the basic features of Euclidean wormholes and their phenomenological applications, focusing in particular on axionic wormholes and the role played by (massive) dilatons in their construction.

- A chiral SU(5) theory with three generations
- Time: 1:00 pm
- Place: Chamberlin 5280
- Speaker: Daniel Stolarski, Carleton University
- Abstract: I will present a study of an interesting strongly coupled chiral quantum field theory. This theory has the same particle content as the simplest grand unified theory of the Standard Model. I will employ tools such as 't Hooft anomaly matching and softly broken supersymmetry to analyze the non-perturbative dynamics of the theory. I will also speculate on the more general lessons of my analysis.
