This book lays out the scientific goals to be addressed by the next-generation ground-based cosmic microwave background experiment, CMB-S4, envisioned to consist of dedicated telescopes at the South…
Completing natural inflation
- Jihn E. Kim, H. Nilles, M. Peloso
- Physics
- 12 September 2004
If the inflaton is a pseudo-scalar axion, the axion shift symmetry can protect the flatness of its potential from too large radiative corrections. This possibility, known as natural inflation,…
A precision calculation of the effective number of cosmological neutrinos
- G. Mangano, G. Miele, S. Pastor, M. Peloso

Phenomenology of a pseudo-scalar inflaton: naturally large nongaussianity
- N. Barnaby, R. Namba, M. Peloso
- Physics
- 21 February 2011
Many controlled realizations of chaotic inflation employ pseudo-scalar axions. Pseudo-scalars are naturally coupled to gauge fields through cF. In the presence of this coupling, gauge field quanta…
CMBPol Mission Concept Study Probing Ination with CMB Polarization
- D. Baumann, M. Jackson, M. Zaldarriaga
- Physics
- 24 November 2008
We summarize the utility of precise cosmic microwave background (CMB) polarization measurements as probes of the physics of ination. We focus on the prospects for using CMB measurements
Science case for the Einstein telescope
- M. Maggiore, C. Broeck, M. Sakellariadou

- 5 December 2019
The Einstein Telescope (ET), a proposed European ground-based gravitational-wave detector of third-generation, is an evolution of second-generation detectors such as Advanced LIGO, Advanced Virgo,…
Science with the space-based interferometer LISA. IV: probing inflation with gravitational waves
- N. Bartolo, C. Caprini, G. Tasinato
- Physics
- 20 October 2016
We investigate the potential for the LISA space-based interferometer to detect the stochastic gravitational wave background produced from different mechanisms during inflation. Focusing on…
Preheating with trilinear interactions: tachyonic resonance
- J. Dufaux, G. Felder, L. Kofman, M. Peloso, D. Podolsky
- Physics
- 16 February 2006
We investigate the effects of bosonic trilinear interactions in preheating after chaotic inflation. A trilinear interaction term allows for the complete decay of the massive inflaton particles, which…
Suppressing the lower multipoles in the CMB anisotropies
- C. Contaldi, M. Peloso, L. Kofman, Andrei Linde
- Physics
- 31 March 2003
The Cosmic Microwave Background (CMB) anisotropy power on the largest angular scales observed both by WMAP and COBE DMR appears to be lower than the one predicted by the standard model of cosmology…
Gravity waves and non-Gaussian features from particle production in a sector gravitationally coupled to the inflaton
- N. Barnaby, Jordan Moxon, R. Namba, M. Peloso, G. Shiu, P. Zhou
- Physics
- 26 June 2012
We study the possibility that particle production during inflation could source observable gravity waves on scales relevant for Cosmic Microwave Background experiments. A crucial constraint on such…
