Exploring Parameter Constraints on Quintessential Dark Energy: the Pseudo-Nambu Goldstone Boson Model

Abstract

We analyze the constraining power of future dark energy experiments for Pseudo-Nambu Goldstone Boson (PNGB) quintessence. Following the Dark Energy Task Force methodology, we forecast data for three experimental ``stages'': Stage 2 represents in-progress projects relevant to dark energy; Stage 3 refers to medium sized experiments; Stage 4 comprises larger projects. We determine the posterior probability distribution for the parameters of the PNGB model using Markov Chain Monte Carlo analysis. Utilizing data generated on a $\Lambda CDM$ cosmology, we find that the relative power of the different data stages on PNGB quintessence is roughly comparable to the DETF results for the $w_0-w_a$ parametrization of dark energy. We also generate data based on a PNGB cosmological model that is consistent with a $\Lambda CDM$ fiducial model at Stage 2. We find that Stage 4 data based on this PNGB fiducial model will rule out a cosmological constant by at least $3\sigma$.
