High Energy Theory Seminar

A Perfect Bounce
Neil Turok
1:45pm|Bloomberg Lecture Hall

We study the quantum cosmology of a universe with conformal matter. For homogeneous, isotropic metrics and matter, the quantum gravitational path integral may be performed exactly. The result is a "perfect bounce," in which the universe passes...

High Energy Theory Seminar

Topologically Twisted Index and Casson-Walker Invariant
Pavel Putrov
1:45pm|Bloomberg Hall Physics Library
In the beginning of my talk I will review some general facts about 3d-3d correspondence and describe how to construct 3d theory T[M_3] associated to a Seifert 3-manifold M_3. Then I will show how one can calculate the Casson-Walker invariant of M_3...

6d (2,0) Theories From the Ground Up
Clay Cordova
1:45pm|Bloomberg Lecture Hall

I will survey some properties of the 6d (2,0) theories that can be determined using only their symmetries. In particular, I will discuss their anomalies, moduli spaces, ADE classification, and the relation to 5d super Yang-Mills.

Network Operators and Quantum Moduli Space of Flat Connections
Maxime Gabella
1:45pm|Bloomberg Lecture Hall
Line operators in class S theories correspond to network operators on the associated Riemann surface. I will describe the algebra of functions on the moduli space of flat SL(N)-connections in terms of a set of networks that are naturally associated...

The Einstein-Rosen Bridge on the String
David Vegh
1:45pm|Bloomberg Lecture Hall

In this talk I review the holographic dual of an entangled pair of a quark and an anti-quark. The bulk dual on the Poincare patch is a string with an Einstein-Rosen bridge on its worldsheet. String solutions will be discussed that correspond to...

Colorless Top Partners, Naturalness and the Higgs
Gustavo Burdman
1:45pm|Bloomberg Lecture Hall

The LHC data are severely constraining natural theories of electroweak symmetry breaking.

An important part of the constraints comes from the fact that typically the partners of the top quark in carry color and can be profusely produced at hadron...
