So, can a preon model help to clarify the foundations of physics? As I understand it, part of these foundations is the Brout, Englert, Higgs mechanism (Nobel, 2013). This involves the interaction of certain types of particles with a condensate of weak hypercharge, nowadays called a "Higgs-type...

In those papers linked above (Yershov, 2002-2008), Yershov tried to sketch an alternative to standard model wavicles. By disposing of wavicles, he felt he could also dispose of any Higgs-type field, thus throwing a healthy baby out with the bathwater. And undermining his model. Recent...

Getting back to the issue of the original post, building fermions from some family of preons is a logical next step in a reductionist approach. But such logic raises the question: is there some ultimate preon ("ultimaton") from which a family of such intermediate preons might be built? This sort...

Good point. The way Lenny Susskind used to explain those (L,R) fermion states was that the L-state HAS quanta of weak hypercharge, while the R-state does not. In the standard model, the rest mass associated with such a "composite" fermion reduces to the rate of this chiral oscillation. This...

Hi Jaime, I wrote: You replied: Indeed! But by "back yard" and "yardstick", I was thinking of Laniakea. So the "bulk flows, non-homogeneities, or non-isotropies" I had in mind would be on a larger scale, that is to say, external to our local supercluster. Sorry for not being clear.

PS: what a great set of slides from Wendy! As ohwilleke points out (just above), part of this tension may be related to the fact that calibration of distance ladders is done within the local supercluster (Laniakea). Any unaccounted-for bulk flows, non-homogeneities, or non-isotropies beyond...

Mitchell, your post #10 above really helped to clarify relationships between Weyl spinors, Dirac spinors and chiral states of standard model electrons. Thanks for taking the time! And thanks also for pointing to Haelfix's description of linear combinations of (non-Higgs) excitations of a...

Mitchell, thanks for another such thoughtful and helpful reply. Before getting back to the issue of non-homogeneity in the distribution of weak hypercharge, can you clarify something about the way the standard model currently models interaction with this distribution? Back in message #4 above...

Thanks Mitchell - that DOES sharpen the focus! Following this lead and shifting into the local frame of a superposition of entangled spinors, a necessary precursor to Weyl modes would seem to be Planck's quantum of angular momentum. But given (1) the way quantized angular momentum is connected...

Mitchell, thanks for sketching sound foundations. Indeed. So assuming that this percussive (125 GeV) disturbance is not required to enable the chiral oscillation of fermions, or the oscillatory weak-hypercharging of Z-bosons, is it correct to associate such a "boson" with the mechanism...

Thanks Mitchell - interesting possible "causes" for possible non-homogeneity... :wideeyed: Before going on, with regard to interaction with a standard-model type of condensate of weak hypercharge, can someone clarify the difference between the sort of density disturbance the LHC can cause (and...

Thinking about the apparently rapid formation of galaxies in the early universe, is it possible for inhomogeneities to form, or even to exist, in a Higgs-type field? If so, given the energy associated with such a (Higgs-type) condensate of weak hypercharge, could such inhomogeneities help to...

Thanks Ibix - understood. I'll switch to wondering about what sort of mechanism might allow for variation in the global distribution of weak hypercharge, and what (if any) effect this could have on electromagnetic propagation. I'll take this where it belongs :sorry:

Hi Ibix, Since all media have well-defined permittivity and permeability, and the speed of light through those media is dependent on that permittivity and permeability, I had to wonder... if that ratio of 299792.458 km/s were in fact dependent on the local value of ##\epsilon## and ##\mu##...

Indeed! But wouldn't that local ##c## (as measured in an inter-cluster void) be a different number of local ##km/s##?
