Motti Intermediate Physics — HAL: Dark Energy Equation of State w(z) — Prediction and Comparison with DESI 2024

Key Points

• The aim is to predict the dark energy equation of state w(z) and compare it with DESI 2024 results.
• Prediction of w(z) based on HAL model with parameters Omega_Lambda and Omega_m.
• Analysis of current datasets including DESI Y1.
• Comparison of future predictions with DESI and Euclid measurements.
• HAL predicts w0 = -0.99666 and wa > 0, which suggests an increasing w with redshift.
• DESI Y1 reports w0 = -0.827, showing a 2.7 sigma tension with HAL predictions.
• Future tests by Euclid in 2028 may provide further insights into the behavior of w.
