An Inverted Mass Hierarchy for Excited Dark Matter
Andrew Frey - University of Winnipeg
Varied experimental results have recently sparked theoretical interest in the dark matter sector. I will review some of these results and the basic ideas in particle physics that might explain them, as well as some requirements for those models to work. Then I'll discuss a new model dark matter… -
Brane Tilings, M2 Branes and Chern Simons theories
Amihay Hanany - Imperial College London
Brane Tilings are known to describe the largest known class of SCFT's in 3+1 dimensions. There is a well established formalism to find AdS_5 x SE_5 duals to these SCFT's and to compare results on both sides. This talk extends this formalism to 2+1 dimensional SCFT's, living on the world volume of M2… -

Redesigning Electroweak Theory: Does the Higgs Particle Exist?
John Moffat - Perimeter Institute for Theoretical Physics
An electroweak model in which the masses of the W and Z bosons and the fermions are generated by quantum loop graphs through a symmetry breaking of the vacuum is investigated. The model is based on a regularized quantum field theory in which the quantum loop graphs are finite to all orders of… -
Introduction to the Bosonic String 5B
Alex Buchel - Western University
This course provides a thorough introduction to the bosonic string based on the Polyakov path integral and conformal field theory. We introduce central ideas of string theory, the tools of conformal field theory, the Polyakov path integral, and the covariant quantization of the string. We discuss… -
The Tail that Wags the Dog: Observational Constraints on Dark Matter Halos in Nearby Galaxies
Kristine Spekkens - Royal Military College of Canada
The standard cosmological framework explains an impressive range of large-scale astrophysical phenomena, but an agreement between its predictions and the properties of the dark matter halos of nearby galaxies has not been established. In this talk, I will highlight some key observables that… -

This course provides a thorough introduction to the bosonic string based on the Polyakov path integral and conformal field theory. We introduce central ideas of string theory, the tools of conformal field theory, the Polyakov path integral, and the covariant quantization of the string. We discuss… -
Measuring Black Hole Spin
Ramesh Narayan - Harvard University
An astrophysical black hole is completely described with just two parameters: its mass and its dimensionless spin. A few dozen black holes have mass estimates, but until recently none had a reliable spin estimate. The first spins have now been measured for black holes in X-ray binaries. -
The World as a Hologram?
Richard Epp - University of Waterloo , Robert Myers - Perimeter Institute for Theoretical Physics
PIRSA:09020042Our universe has a split personality: quantum and relativity. Understanding how the two can coexist, i.e. how our universe can exist, is one of the greatest challenges facing theoretical physicists in the 21st century. Join us for a simple but mind-bending thought experiment that hints at some… -
Quantum algorithm for Statistical Difference problem
Sergey Bravyi - IBM (United States)
Suppose we are given two probability distributions on some N-element set. How many samples do we need to test whether the two distributions are close or far from each other in the L_1 norm? This problem known as Statistical Difference has been extensively studied during the last years in the field… -
Evidence for the Black Hole Event Horizon
Ramesh Narayan - Harvard University
Astronomers have discovered many candidate black holes in the universe and have studied their properties in ever-increasing detail. Over the last decade, a few groups have developed observational tests for the presence of event horizons in candidate black holes. The talk will discuss one of these…
