6D Brane Models and their Perturbations
Susha Parameswaran - University of Liverpool
Models with two supersymmetric large extra dimensions (SLED) may provide a way to approach both the cosmological constant problem and dark energy. After reviewing these ideas, I shall discuss warped brane world solutions in 6D supergravity, as a laboratory in which to explore SLED and codimension… -
Inflation on a codimension-two brane
Hyun Min Lee - Carnegie Mellon University
We consider a codimension-2 brane inflation scenario in a warped flux compactification of 6D gauged supergravity. The volume modulus of the model is stabilized by means of potentials localized on the regularized background branes. We discuss the cosmological evolution of the world-volume of a probe… -
Infrared Modification of Gravity with Dynamical Torsion
Seifallah Randjbar-Daemi - The Abdus Salam International Centre for Theoretical Physics (ICTP)
Theories of gravity having connection as an independent dynamical variable can have a massive spin -2 particle together with the massless graviton in their spectrum. We study the potentiality of such models as a consistent infrared modification of gravity. It will be shown that these models are free… -
Phenomenological Connections between Particle Physics and Dark Energy
Daniel Chung - University of Wisconsin–Madison
I explore possible connections between the Higgs sector and dark energy -
Positive and Negative Energy Symmetry and the Cosmological Constant Problem
John Moffat - Perimeter Institute for Theoretical Physics
The Hamiltonian for the quantized gravitational and matter fields contains both positive and negative energy particle contributions, which leads through a positive and negative energy symmetry of the vacuum to a cancellation of the zero-point vacuum energy and a vanishing cosmological constant in… -

Where in the String Landscape is Quintessence.
Nemanja Kaloper - University of California, Davis
I will make the case that the Bousso-Polchinski landscape may contain quintessential corners. -
