Phenomenology of Inflaton-Driven Early QCD Confinement and Solution to Axion Isocurvature Problem
Evangelos I. Sfakianakis, Barmak Shams Es Haghi, Katherine Freese
We study the phenomenology of early QCD confinement during inflation, driven by a direct coupling between the inflaton and Standard Model gluons. This coupling dynamically raises t…
Isocurvature-Free QCD Axion Dark Matter from Inflaton-Driven Early QCD: the Necessity of Inflationary Plateaus
Katherine Freese, Evangelos I. Sfakianakis, Barmak Shams Es Haghi
A direct coupling between the inflaton and Standard Model gluons can dynamically raise the QCD confinement scale during inflation, making the axion temporarily heavy and suppressin…
Conversations and Deliberations: Non-Standard Cosmological Epochs and Expansion Histories
Brian Batell, Keith R. Dienes, Brooks Thomas +17
This document summarizes the discussions which took place during the PITT-PACC Workshop entitled "Non-Standard Cosmological Epochs and Expansion Histories," held in Pittsburgh, Pen…
Dark radiation constraints on light primordial black holes
Jérémy Auffinger, Alexandre Arbey, Pearl Sandick +2
Light black holes could have formed in the very early universe through the collapse of large primordial density fluctuations. These primordial black holes (PBHs), if light enough,…
