HIP NEWS September 9th 2013
==============================
Dear HIP Personnel,
—————————
HIP Website will be updated soon.
The web pages will be moved to virtual servers,
and the old server becomes obsolete.
We will try to keep most of the old links working,
but some changes may occur. If you notice any abnormal
things/behavior in the new website, please do not
hesitate to send email to webmaster@hip.fi
HIP can provide webspace for the HIP projects, workshops etc.
(WordPress). If you need help, please contact support@hip.fi
The access to the old web server is restricted during the
transition. Again, if you have any questions, please contact
support@hip.fi
Best Regards,

News from Quantum Gravity Phenomenology
Abstract: I will talk about recent developments in the search for experimental signatures for quantum gravitational effects. Some of the topics that I will cover are the prospects of finding Planck scale effects in gamma ray bursts, in neutral Kaon oscillations, or with massive quantum oscillators. I will also comment on the possibility of finding holographic noise and, if time permits, on Bekenstein’s proposed table top experiment.This is not a review talk; it is a hand selected assortment of topics I think are interesting.

A new mechanism for curvature perturbations
I will explain the spectator scenario and show its advantages compared to the curvaton scenario, under the latest Planck constraints. The spectator scenario generates a smaller non-Gaussianity, negligible isocurvature perturbations, and less tuning. It agrees well with the current Planck data in the visible sector inflation setup, as an example. It also explains the CMB dipole asymmetry with a brief fast roll phase. I will close the talk by proposing the CMB power multipoles, as an alternative approach independent of the CMB dipole asymmetry model.
