CONOS Results out.
Any new force between neutrinos and quarks, might be detected in scattering between neutrinos and nuclei - such as coherent elastic neutrino nucleus scattering (CEvNS) processes. Experiments have recently improved to be able to detected such scattering, and one such experiment CONUS has reported results last month with PDF Presentation. Results include, limits on neutrino magnetic moments, of less than 7.5*10^-11 Bohr Magnetrons at 90% CLL. Also neutrino millicharge
less than 3.3*10^-12 of the electron charge at 90% CL. There are also some limits quote on non standard neutrino interactions (which i what am in interested in), but the limits are 90% C.L. limit is factor ~2 above SM prediction.
New Particle Claim, X at 17 MeV.
In my weekly, literature search, I found, the preprint by Denton and Gehrlein, which investiages evidence for a 17 MeV boson, in nuclear decays, which itself decays to an electron position pair. The Authors found, the new particle, could be a mediator for the
often suggested (B-L) symmetry (Baryon number minus Lepton Number), which often crops up in grand unification theorys (for example, Patti Salem). However the charges on quarks, electrons, and neutrinos, need to be different to pure (B-L), which may be explained, by breaking the (B-L) symmetry with a new Higgs Boson, and then also introducing Kenetic mixing the EM photon, as explained in Feng et Al.
The 17 MeV particles, has previously generated quite a bit of interest, and was reported in scientific journalism, (e.g. physics world).

High Energy Gamma Rays found from distance long Gamma Ray Bursters, are they axiphotons.
The Gamma Ray Burster, GRB 221009A Is mystery to modern physics. Observations found Gamma Rays up to 18TeV in Energy. But above 15GeV, the GZM mechanism, "R. C. Gilmore, R. S. Somerville, J. R. Primack, and A. Dominguez, Mon. Not. R. Astron. Soc. 422, 3189 (2012)." Shows that any higher energy photons would scatter of cosmic background radiation, producing pions. So what was travelling the 645 MegaParsecs from the Gamma Ray Burster if not a photon? Suggests a decaying heavy neutrino. While Looks at Axion Like Particles.
Could it be a axi-photon, the vector particle associated with the a new axial force between neutrinos. I will have to see if the axi-photon scattering on cosmic background neutrinos, and any other axi-photons is suppressed at higher energies, and get back to you.
Are Volcanos Linked to the Solar Cycles.
In Arxiv:2203.03637, Valentina Zharkov Shows links between the 22-year Solar Cycle, and Volcanic Activity. During Solar Cycle 26, from 2031-2041, Volcanos would be a maximam, cooling the Earth, with possible effects on Food Production, if she is correct. This would mean that any Net Zero Plan, aiming
targets at 2030, would leave the planet cold and hungry. Over the longer term, her mechanism would average out.
I wonder if the effect of the Earths Iron Core, passing through the Suns magnetic field that reverses each 11 years. Could be the mechanism of her effect. The Earth has its own electric current in its magnetic dynamo, and when the
Earths Natural Current is aligned with the current Induced by the Sun, an increased current will heat the Earths Core. If I have time, I will look into quantifying the numbers for this mechanism. Zharkov is a Plasma Physicist, so should also be more than capable of quantifying the numbers.

Ryzen Benchmarks
My Multithreaded integrator (Threaded Simpsons Rule), http://axitronics.blogspot.com/2022/02/need-multithreaded-numerical-integrator.html, is highly parallel. Lets see how it performs on recent processors Ryzen 9, 5900
versus my old processor Ryzen 5, 2600 @3400, 6 Core.
Nice so after 3 years, a new processor performs at double speed (well 75% faster) of the older one, (if a bit more expensive). Moore's Law is still alive in 2022.
| Processor | Cores | Clock Speed | CPU Threads | Java Threads set for calculation | JDK Version | Time to Run climate calculations - Seconds | |
|---|---|---|---|---|---|---|---|
| AMD Ryzen 5 | 6 | 3400 MHz | 12 | 16 | Oracle JDK 11.0.17 | 10332 | |
| AMD Ryzen 9 | 8 | 4600 Mhz | 16 | 32 | Oracle JDK 17.0.5 | 5959 |

Half Up, Half Down
Looking at the rainfall effect on climate sensitivity calculation, in the early post, we can see if half the energy of condension to rainfall goes up and half goes downwards, the energy emitted to spaces, is on 40.05 W/m^2, and so entering into our formule, the temperature increase due to doubling CO2 from 400ppvm to 800ppvm is 0.39 Degree (K or C).

Cabibbo Angle Anomaly
Found a interesting paper on ArXiv, Explaining the Cabibbo Angle Anomaly, in which
A. Crivelin, summaries ways of explaining the matrix of transition amplitudes for up type quarks being turn to down type quarks of the same of different generations. This Cabibbo Matrix is not unitrary at 3 sigma, but it has to be unitary in fact. Crivelin shows that it could be explained as the weak force being strong in muon decay than in interactions between quarks, 3.4 Sigma discrepancy between the Fermi (Weak force strength) Constants.
GCKM F = 0.99925(25) × G muon.
So we need a theory that can give muon weak decay slight stronger amplitude, but be the lower for quark decay. Our Axial force does that, the relavent diagram for muon decay, being,
If the axial force constant is A, this makes G muon bigger by (1+A) approximately. We hope to compute the diagram correctly later. The quark decay via the weak force, also picks up an axial force correction. But the correction depends on the axial force charges on the quarks, and for our favourite pick of half on u quarks and minus a half on d quarks, that exactly cancels out. Too explain the muon fermi constant being 1.00075 strong, we need an Axial force constant of one tenth the strength of the electromagnetic field, one tenth the fine structure constant. This is eight time stronger than my guess from renormalation flow, but experimental bound on neutrino neutrino interactions are very weak, and nucleus neutrino interactions, only recently have been measured.
The Cabibbo Angle Anomaly is only 3.4 sigma so might disappear with future measurement. The axial force is not the only explination for it,
Crivelin lists 6 possible BSM physics that might explain, with the axial force falls into 3.5 SU (2)L Neutral Vector Boson (Z′):. Crivellin also, with others, worked on https://arxiv.org/pdf/2104.07680.pdf, looking at an extra Z` but that force, was massive and coupled to the charged leptons. The axial force couples to neutrinos and quarks, only in our model, thus escaping experimental constraints.
