Nordita East seminar room (132:028)
The second TWG meeting of the year will be this Thursday (tomorrow), Jan. 28, at 13.15 in the Nordita East seminar room (132:028). Since Paolo gave an introduction last week, Matin and I will dive into the specifics of our work (http://arxiv.org/abs/1512.03316).
The discussion will be about:
- How tree level, on-shell gauge invariance can be used to fully determine the leading, sub-leading, and sub-sub-leading behaviors of soft gravitons as well as soft "gravity dilatons," i.e., the dilatons that appear in theories of (super)gravity and in string theories.
- How Ward identities of conformal symmetry can be used to fully determine the leading, sub-leading, and sub-sub-leading behaviors of soft Nambu-Goldstone dilatons that generically appear in theories of spontaneously-broken conformal symmetry.
- How the soft behavior of gravity dilatons and Nambu-Goldstone dilatons are related.
