| 13:30 - 15:00 Weekly Seminar Extended Effective Field Theory of Inflation School ASTRONOMY I present a general framework where the effective field theory of single field inflation is extended by the inclusion of operators with mass dimension 3 and 4 in the unitary gauge. These higher dimensional operators introduce quartic and sextic corrections to the dispersion relation. I study the regime of validity of this extended effective field theory of inflation and the effect of these higher dimensional operators on the CMB observables associated with scalar perturbations, such as the speed of sound (including the time-dependent case), the amplitude of the power spectrum and the tensor-to-scalar ratio. Tensor perturbations remain instead ... 16:00 - 18:00 Neuroimaging Journal Club Neural mediators of changes of mind about perceptual decisions School COGNITIVE SCIENCES Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran ... |
