But, I don't think that the neutrinos are actually Majorana fermions and I don't think that it involves right handed neutrinos via a see saw mechanism.<br /><br />I also think that the role of the W boson (and to a less extent other electroweak processes) in allocating the Higgs field to Standard Model fundamental particles is underestimated and not fully appreciated. I think that to escape the question begging of the Standard Model Higgs boson mechanism that replaces the question of "why are the fundamental masses what they are?" with "why are the yukawas what they are?", you need to have a process in which the W boson and Higgs (and to a lesser extent photons and Z bosons, but not gluons or gravitons) make first order contribution to the rest masses of the fundamental SM particles in some sort of joint process, with the weak coupling constant setting the overall electroweak mass scale via the Higgs vev which is a function of the weak coupling constant. A more fully elaborated combined Higgs-electroweak process for generating fundamental particle masses may mesh better with Dirac neutrinos than the SM Higgs process explanation which can be simpler due to left-right parity symmetries in the other fundamental fermions.<br /><br />The lightest neutrino mass and the electron mass can both be explained very plausibly as entirely derived predominantly from their own self-interactions - at tree level via photons and W and Z bosons in the case of the electron, and via W and Z bosons in the case of the lightest neutrino mass, with adjustment from higher order loops.<br /><br />The ratio of the charged lepton masses and of the quark masses can be seen as arising from a dynamic balancing of different flavors via W boson interactions (with the charged leptons being the simplest because the neutrino masses are all so tiny that they induce only tiny modifications from neutrinos not existing at all). W boson transformations of heavy fermions into lighter ones pulling the heavier fermions slightly down and pulling the lighter fermions slightly up. <br /><br />For example, the up quark mass at first order is due to its self-interactions, but is tugged up by bottom quark to up quark and strange quark to up quark interactions, in a manner that is a function in some manner of the probability of such interactions. Similarly, the down quark mass at first order is due to its self-interactions, but it tugged up by the top quark to down quark and charm quark to down quark interactions, in a manner that is a function in some manner of the probability of such interactions.<br /><br />I like the on shell account of neutrino oscillation that I blogged about recently, as it derives the process from virtual W boson interactions, rather than the more conventional mass-weak force state mismatch approach.<br /><br />While this tentative ansatz is incomplete (e.g., it doesn't explain why there are exactly three generations in the first place, and the exact equations aren't worked out, let alone the full calculations, and there are additional electroweak theory considerations the apply to the fundamental bosons), it gets you very close to what is observed in a very minimalist manner.<br /><br />andrewhttps://www.blogger.com/profile/08172964121659914379noreply@blogger.comtag:blogger.com,1999:blog-7315236707728759521.post-6342623835239820952021-04-28T16:34:50.195-06:002021-04-28T16:34:50.195-06:00You believe in Dirac masses for neutrinos I think,...You believe in Dirac masses for neutrinos I think, via couplings to the known Higgs... That would be a kind of Higgs portal to the "right hand neutrino" sector, albeit it would be undetectable because of how small the yukawa couplings are?Mitchellhttps://www.blogger.com/profile/10768655514143252049noreply@blogger.com
