PIRSA:13070006  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Precision Holographic Cosmology
Speaker(s): Paul McFadden
Abstract: We discuss holography for cosmology, focusing on a class of slow-roll inflationary spacetimes that are holographically dual to a perturbative RG flow between two nearby CFTs.   The cosmological power spectrum and non-Gaussianities may be calculated directly from the dual QFT using ... read more

PIRSA:13070025  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Cosmological Limits on Neutrino-Neutrino Scattering and Particle Physics in the Early Universe
Speaker(s): Kris Sigurdson
Abstract: In the standard model neutrinos are assumed to have streamed across the Universe since they last scattered at the weak decoupling epoch when the temperature of the standard-model plasma was ~MeV. The shear stress of free-streaming neutrinos imprints itself gravitationally on the Cosmic Microwave Bac... read more

PIRSA:13070005  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Solid Inflation
Speaker(s): Alberto Nicolis
Abstract: I will describe a cosmological model where primordial inflation is driven by a 'solid', defined as a system of three derivatively coupled scalar fields obeying certain symmetries and spontaneously breaking a certain subgroup of these. The symmetry breaking pattern differs drastically from that of st... read more

PIRSA:13070021  ( MP4 Medium Res , MP4 Low Res , MP3 , PDF ) Which Format?
Bimetric theory, Conformal Gravity and Partial Masslessness
Speaker(s): Fawad Hassan
Abstract: Ghost-free bimetric theories can be used to describe  gravitational interactions in the presence of an extra neutral massive spin-2 field that can modify gravity in non-trivial ways. They also provide a natural framework for a possible non-linear extension of partially masslessness known to... read more
