CMB Injection Bounds on Moduli Fields
Naman Agarwal, Andrew R. Frey, Ratul Mahanta +3
Light scalar fields with gravitational strength interactions (moduli) are ubiquitous in string, supergravity, and extra-dimensional models. If produced in the early universe with l…
Gravitational Waves from the Hagedorn Phase
Gonzalo Villa
We illustrate the main points behind the computation of the gravitational wave spectrum originated from a phase in the early universe where the energy density is dominated by highl…
Back to the origins of brane-antibrane inflation
Michele Cicoli, Christopher Hughes, Ahmed Rakin Kamal +4
We study a new framework for brane-antibrane inflation where moduli stabilisation relies purely on perturbative corrections to the effective action. This guarantees that the model…
Gravitational Waves from High Temperature Strings
Andrew R. Frey, Ratul Mahanta, Anshuman Maharana +2
We study finite temperature effects in string cosmology and their potential gravitational wave signature. Expanding on our recent work arXiv:2310.11494 , we consider a general conf…
String Thermodynamics In and Out of Equilibrium: Boltzmann Equations and Random Walks
Andrew R. Frey, Ratul Mahanta, Anshuman Maharana +3
We revisit the study of string theory close to the Hagedorn temperature with the aim towards cosmological applications. We consider interactions of open and closed strings in a gas…
Testing BSM Physics with Gravitational Waves
Francesco Muia, Fernando Quevedo, Andreas Schachner +1
The Cosmic Gravitational Wave Background (CGWB) is an irreducible background of gravitational waves generated by particle exchange in the early Universe plasma. Standard Model part…
