Motti Intermediate Physics — HAL: Dark Energy Equation of State w(z) — Prediction and Comparison with DESI 2024
Year: 2026
Type: preprint
Abstract: HAL predicts w(z) = -Omega_Lambda/(Omega_Lambda + alpha_em x Omega_m x (1+z)^3). At z=0: w0 = -0.99666. Positive wa (w increases with z). DESI Y1 gives w0=-0.827 (2.7 sigma tension, dataset-dependent). Euclid 2028 will test: HAL predicts wa>0, DESI Y1 finds wa<0.
