We present a dark energy (DE) model as a natural extension of the standard model of particle physics where the lightest bound state, a scalar particle phi, corresponds to DE. The potential V = Lambda(4+2/3)(c) phi(-2/3) is dynamically formed at the condensation energy scale Lambda(c) and scale factor a(c). Our DE model has excellent agreement with current cosmological data improving the fit of baryon acoustic oscillation (BAO) measurements, specially designed to determine the dynamics of DE, from (chi(2))(BAO)(Lambda CDM) = 7.115 in the standard cold dark matter model with a cosmological constant (ACDM) model to difference of Delta chi(2)(BAO) = 1.5 and a likelihood ratio of 2.1. We obtain an exact constraint a(c)Lambda(c)/eV = 1.0939 x 10(-4) and a theoretical prediction on Lambda(c) = 34(-)(11)(+16) eV, consistent with the best fit Lambda(c) = 44.08 +/- 0.27 eV, while in the standard ACDM there is no understanding of the value of the cosmological constant A. Remarkably, our model prediction on a(c)Lambda(c) has a relative difference of only 0.2% with the best fit value if we allow a(c) and Lambda(c) to vary independently. Unlike a cosmological constant Lambda, our DE model predicts the amount of DE and leaves detectable cosmological imprints at different times and scales at a background and perturbation level.
