Radiation-matter transition in Jordan-Brans-Dicke theory
Radiation-matter transition in Jordan-Brans-Dicke theory
We study the transition from radiation domination to matter domination in Jordan-Brans-Dicke theory, in particular examining how the Hubble length at equality depends on the coupling parameter $\ensuremath{\omega}.$ We consider the prospects for using high-accuracy microwave anisotropy and large-scale structure data to constrain $\ensuremath{\omega}$ more strongly than by conventional solar …
