Hiding dark light from a dark force rrom the sun.
Suppose there was an extra force with a weak coupling to a nucleon. The stefan boltzmann law would then have the sun shine an equal amount of dark light as regular lighht even if the coupling was weak, energy in wave equipartions, so thesun would lose twice as much energy with twice the amount of force carriers. We would have noticed the extra energy loss, and maybe detected the extra energy on earth.
How can we concell this dark light. Suppose dark matter is a good conductor of the dark force. For example if dark matter is sterlie neutrinos and the dark force is our axial force between neutrinos (and also nucleons). Such a conductor would reflect the dark light. We would suppose that the dark matter is held some distance away from the sun, by the energy of the dark light reflected by it, equalling the gravition attraction of its mass. For a good conductor all the dark light would be hidden. There would be a convection zone where the enerhy of dark light is absorbed. This might be the reason the solar corona is a million degrees, while the surface of the sun is only 6000 degrees C.

Limits on new gauge vector forces and associated mass giving scalars for Z decay
The new paper at ArXiv https://www.arxiv.org/abs/2501.04388 by Peli and Trocsanyi linit show how Higgs Bosons decay measurements can limit new Bosons. The current measurement of Z width is not yet strong enough to limit all new models.
The SM theoretical prediction for the Higgs boson width is ΓSM h = 4.07 MeV, with a relative uncertainty of 4% [3]. The experimental measurements on the other hand are ΓATLAS h = 4.5+3.3 −2.5 MeV [17] and ΓCMS h = 3.2+2.4 −1.7 MeV [18], display a much larger uncertainty than the SM theoretical prediction allowing for several BSM models to remain compatible with observations.

Nova and T2K find non unitary mixing 3 sigma - Excess Neutrinos more than expected from oscillations - Neutrino Decay or Neutrino Pair Production
In https://www.arxiv.org/pdf/2501.00146 Yu et al Analysis results from the 295 Kilometer far detector from J-PARC, T2k, and the 810 Kilometer far detector at Fermilab both with Gev Muon Neutrino, both seem to show excess electron neutrinos more than can be expect from Unitary (Preversing Particle Number) Oscillations of Neutrinos, the Nova detector show this much more strongly than T2k. Could Muon Neutinos be pair producing electron neutinos by scattering along the way, v_mu->v_mu + v_e + v-bar_e? As our axial force might do. The amount of extra electron neutrinos is 6% averaged over both experiments.
