String theory and the dark glueball problem
- Abstract:
-
We study cosmological constraints on dark pure Yang-Mills sectors. Dark glueballs are overproduced for large regions of ultraviolet parameter space. The problem may be alleviated in two ways: via a large preferential reheating into the visible sector, motivating certain inflation or modulus decay models, or via decays into axions or moduli, which are strongly constrained by nucleosynthesis and ΔNeff bounds. String models frequently have multiple hidden Yang-Mills sectors, which are subject to...
