DESI results don't favour a cosmological constant but a varying quintessence of some form.
The DESI results using Baryon Ascotic oscillations together with supernova spectrum to find galaxy velocity, seem at (3.4 Sigma) not to favour the
cosmological constant but an dark energy or quintessence that reduces with time. Combined results have the equation of state parameter as 0.86 +.10 -.11.
Zheng et al in https://arxiv.org/abs/2412.04830
Remember our axial force modelled qunintessence as a neutrino dark energy caused by the attractive force between neutrinos, which we estimate an
equation of state or owega of 17/18 or 0.94444.
