| contents | <p>We present the first confrontation of the DAIMON v2.1 model –a canonical scalar-field framework driven by an informational energy component– with current cosmological observations. In this formulation, the cosmological constant is replaced by a dynamically evolving density, Ωinfo(z), parameterized through a log-normal activation profile peaked at intermediate redshift. Unlike many alternative dark-energy scenarios that either violate physical consistency (e.g., phantom models) or fail to simultaneously fit multiple datasets, DAIMON remains strictly canonical, guarantees w(z) ≥ −1 across the entire redshift range, and yields a smooth, monotonic evolution of both φ(z) and V (φ).<br>Using the Pantheon+ supernova sample in combination with BAO measurements from SDSS/BOSS, we show that DAIMON achieves competitive fits without fine-tuning. A grid-based χ2 analysis identifies regions of parameter space that minimize residuals while ensuring Ωinfo(z) ≪ 10−2 at recombination, thereby preserving compatibility with CMB distance priors. These results establish DAIMON v2.1 as a theoretically robust and observationally competitive alternative to ΛCDM, offering not only empirical adequacy but also a distinct ontological interpretation rooted in informational cosmology.</p> |
