Neutrinos are among nature’s most elusive particles. They have tiny masses and can change between three types as they travel. Explaining both their masses and this “mixing” is an important challenge for any deeper account of particle physics. Physical Bath Selection and Neutrino Mixing in VERSF investigates how these properties could emerge from the underlying structure proposed by VERSF, including its “physical bath”—the surrounding substrate activity that helps determine a particle’s behaviour.
The paper brings together the ingredients needed to calculate neutrino masses and mixing within one consistent construction. It also tests a concrete candidate and finds why it fails: applying the same generation-weighting rule to neutrinos as to charged particles produces masses that are far too widely separated and mixing that is too restricted. This is useful progress because it identifies a specific limitation of the tested construction and establishes what a successful replacement must overcome.
A further calculation explores how a folding process in the substrate could supply the missing structure. Under a stated assumption about how the generations are related, the fold produces two distinct patterns of response that could help distinguish the three neutrino generations. The simplest implementation gives the wrong pattern of mass differences, however, and the present equations do not yet select the fold’s orientation. The paper traces these difficulties to a specific missing connection between physical substrate currents and the way the underlying activity evolves.
This advances VERSF’s broader effort to derive the Standard Model’s particle structure and interactions while also accounting for neutrino masses. It connects previously separate results, rules out a concrete unsuccessful construction and identifies a more precise next calculation. A complete prediction of neutrino masses and mixing remains unfinished, but the route towards it is now more constrained: the remaining physical inputs are clearer, and future calculations have explicit tests they must pass.
