Motti Intermediate Physics — HAL: Matter Fluctuations, Neutrino Mass Bounds, and Phase Transition Gravitational Waves

Key Points

This research aims to explore cosmological predictions related to neutrino masses and gravitational waves.
Analyzed three HAL cosmological predictions regarding sigma_8, neutrino mass bounds, and phase transition gravitational waves.
Sigma_8 predicated at 0.7980, addressing sigma_8 tension (reduction of -1.6%).
Neutrino mass bound established at sum(m_nu) < 0.11913 eV, a decrease of -0.87 meV.
Phase transition gravitational waves enhanced by C0^2 = +1.46%.

Abstract

Three HAL cosmological predictions: (1) sigma₈HAL = 0. 7980 (-1. 6%), partially alleviating sigma₈ tension. (2) Neutrino ADM mass bound: sum (mₙu) < 0. 11913 eV (-0. 87 meV). (3) Phase transition GW (QCD, EW) enhanced by C0² = +1. 46%.
