In our retirement we enjoy studying topics in various fields and informally publishing (in online forums or our own document and code repositories) what we have learned (which may take the form of a formal question on occasion).
A few questions had been floating around my mind in 2019 as I finished several years learning quantum mechanics well enough to investigate the behavior of solar neutrinos. In 1976 S. Nussinov had proposed that the length of a solar neutrino packet could be bounded by the beta-plus interval available for its emission in the solar plasma. I found that the packet length was more likely constrained by the lifetime permitted the virtual W-boson in the weak interation process. If the length was constrained solely by plasma collisions the packet length would be on the order of 50 m, which seems unreasonable in light of coherence data available for terrestrially generated neutrinos from nuclear fission. You can read my paper on the subject in your pdf viewer: Bounds on Solar Neutrino Packet Lengths).
After reading my paper in early 2020, a prominent physicist did tell me (in private correspondence) that he agreed with my proposal that "the mass scale of the W boson sets the time scale for the weak interaction that produces a neutrino."
As you may have gathered from some of the entries above, I am active on the Stack Exchange question and answer forums in multiple disciplines:
I also publish computer code and articles at my GitHub account Bentley at GitHub
