Title: Scale v.s. conformal invariance in four dimensions
Host: M.Luty
Room: 432
Abstract: I argue that every unitary scale invariant theory is conformally invariant in four dimensions.
The argument follows that of Luty, Polchinski and Rattazzi, and is based on additional assumptions that:
(1) A kind of crossing symmetry for vanishing matrix elements holds regardless of the existence of the S-matrix. (2) Correlation functions in momentum space are analytic functions other than singularities and branch cuts coming from on-shell processes. (3) The Wightman axioms are sufficient criteria of the locality of an operator.

Title: Dark Matter as a Fundamental Particle
Host: Kaloper
Room: Roessler 55
Abstract:
In this talk I will review past and present ideas about dark matter as
a new fundamental particle, exploring both the underlying theoretical structures as well as the variety of experimental frontiers. Along the way I will try to give you a flavor of some of the most recent developments as well as future plans and prospects.
