Aren't there theoretically any number of kinds of spin-0 bosons like
photons and neutrinos? That are multiple varieties of neutrinos,
various virtual particles.

Let me tell you, you're asking a guy who probably don't know, in terms
of bosons.

To more "accurately" measure the mass of a hadronic particle like the
electrons, protons, and neutrons or their constituent particles quarks,
for which there is no theoretical limit to their smaller particles eg
Technicolor in QCD, Quantum Chromodynamics, to more accurately measure
their mass it takes a higher energy experiment. The running coupling
"constant", in scare quotes because it's running and yet it's
"constant", leads to that the more "accurately" the particle's mass is
measured, the smaller it appears to be, which is why as that data is
experimentally produced over the years in largescale subatomic particle
experiments, the datum of a given type particle has been decreasing by
around an order of decimal magnitude every ten years or so.

Are we still talking about ZF? Listen, indiscernibles are another one
of these concepts, apparently with monographs about it penned by
Leibniz, sets contain no duplicates.

Om. Ohm. The universe is infinite.
