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.

Recent Neutrino Papers

A recently paper from Datta, Marfatia and Mukherjee and also here looked at the B^0->K^0 +inv decay, and hinted that a light scalar acting on neutrinos might be a solution, our light vector similarly could also be a solution. In Li and Yu look at the effective number of neutrinios in the Big Bang, for various Majoron masses. The Majoron is a light scalar that is a popular but undetected method of giving neutrinos masses. In href="https://arxiv.org/abs/2310.13194">Bisset et al Look at potential exclusion limits for Sterile neutrinos from forthcoming Nucleii scattering experiments. In href="https://arxiv.org/abs/2310.13070">Zhang et al Look at the Reactor Neutrino Anomally.

Invisible Beauty Decay, Diagrams for Resolution by New Neutrinophilic Vector Force

The BELLE collabration, has found the first decays of Beauty Measons to Kaons plus invisble, and its much above the standard model prediction (2.8 Sigma confidence). This anomaly could be solved by Neutrino Non Standard Interactions, NSI, such as the Axial Force that I have published about. I have now drawn the diagrams, which are below.
With a similar diagram but for a different generatrion, I found, there was a also a anomaly for the decay of the Kaon, known as the KOTO Anomaly, which is a about 80 times higher than the standard model.
There may be additional diagrams with the axial vertix on the incoming or outgoing quark leg. To complete the calculation I will need to calculate each of the diagrams, and to total the propability amplitudes, each of which contains a factor of the fine structure constant for the axial force or the force strength constant for the axial force squared.

NSI may explain, SN2201009A

A new paper from M. Durhi, Impact of scalar NSI on the neutrino mass hierarchy sensitivity at DUNE, T2HK and T2HKK. It concludes, "In fact, some of the result- ing parameter space of self-interacting neutrino coupling is also in agreement with the parameter space obtained from Hubble tension requirements, allowed (g − 2)μ re- gion and free from other laboratory and cosmology con- straints as well."
The Paper Estimated a force strength of 0.01.

Wow, First Invisible Beauty Decay,

BELLE II and the BaBar Collabrations have found the first 3 sigma, deviations from the SM, BR(B+ → K+ + inv) = (1.4 ± 0.4) × 10−5 Later I will had a possible Feynman Diagram for a 2 W vertix and two Axial Force Vertix, and even later calculate the force strength from the Branching Ratio, and Absolute Magnitude of the Scattering Matrix, Diagram Amplitude. https://arxiv.org/abs/2309.02940

Missinig Neutrinos and Energy, from the SuperNova of 1987A.

The nearest Supernova to the Earth, in modern times, was the Supernova in the Magellaniic Cloud, 1987a, some 168,000 Light Years Aways from us. A few (25) of the neutrinos emitted by the 1987A, where actually measured on Earth, confirming the theory, that it is the neutrinos from the collapse of the inner core of a super nova to become a neutron star, that blow off the outer layers of the star, resulting in the observed supernova. Recently, Shirley Weishi Li et Al, have reanalysised the neutrino data from 1987, and found a deficit in both neutrino counts and neutrino energies, with the observed data, having significantly less number count and energy than the theorectical models of supernova explosions. The star that became the explosion 1987A was the Blue Supergiant Sanduleak 69-202, with a mass of 20 Solar Masses, via a Type II - Core Collapse Supernova, although there are competing theories of it being a binary pair of stars that merged (Supernova Type IA).
