High Energy Theory Seminar

A Cosmological Solution to the Hierarchy Problem
David Kaplan
2:30pm|Bloomberg Lecture Hall

I present a solution to the electroweak hierarchy problem which involves the relaxation of the Higgs mass in the early universe. I will briefly discuss the limits of validity of the model as well as potential experimental signatures.

Soft Dilaton Theorems
Rutger Boels
2:30pm|Bloomberg Lecture Hall

Spontaneously broken conformal invariance appears in many contexts such as a class of Higgs portal models, N>=2 SYM on its Coulomb branch, inflation and target space string theory. In observables this broken symmetry is shown to lead to soft...

Aspects of 6D SCFTs and their Toroidal Compactifications
Michele Del Zotto
2:30pm|Bloomberg Lecture Hall

Six dimensional superconformal quantum field theories are in between the most interesting quantum systems whose existence is guaranteed by stringy arguments. In this seminar I am going to discuss some aspects of their geometric engineering using F...

Goldstone Gauginos
Neal Weiner
2:30pm|Bloomberg Lecture Hall
Experimental constraints on models such as supersymmetry have challenged our assumptions about naturalness, while simultaneously pushing exploration into alternatives that might be more natural. One such scenario is supersymmetry with Dirac...

Non-thermal Dark Matter -- a Generic Prediction of String/M theory
Bobby Acharya
2:30pm|Bloomberg Lecture Hall
Solutions of string/M theory with low energy supersymmetry breaking generically have light moduli fields whose masses are of order the supersymmetry breaking scale. These fields -- whose expectation values parametrise the size and shape of the...
