Limits on neutrino fifth forces from experiments.

https://arxiv.org/abs/2311.14945, has some recent experimental limits on neutrino new forces.

Discrepency between lepton and baryon asymetries.

In https://arxiv.org/abs/2311.16672, ChoeJo, Enomoto et al, look for a solution to a possible discrepency between the ratio of Baryons to photons ((6.14 ± 0.25) × 10−10), the ratio of neutrinos to photons with the EMPRESS, https://arxiv.org/abs/2203.09617, experiment, suggest is (7.5+4.5−3.0) × 10−2. The sphaleron process suggest Delta B = Delta L. How can the extra neutrinos be explained? We had explained a mechanicism in https://vixra.org/abs/0907.0005, In section 14.2, I describe a cassade of pair production via the axial force increasing the number density of neutrino to aproximately 14 million million per cubic meter. The current Baryon density is approximately 1 proton per cubic meter. So our paper estinated 14,000 times to many neutrinos for a lightest neutrino mass of 0.14 meV and the next state being 8 meV, but it is a very effective mechanism for increasing the lepton assymetry. If the next lightest state was near 0.35 meV, the calculate would be a match.
