The road indeed works, and the ground floor starts to appear. Quite impressive progress. #GCP

This is a topic very dear to me, as it is one of the possibilities where we may learn something fundamentally new about the standard model, and the nature of its particles. Research work from us on this can be found e.g. in arxiv.org/abs/2212.08470
Restoring the Bloch-Nordsieck theorem in the electroweak sector of the standard model
The electroweak gauge symmetry cannot be broken in a literal sense due to Elitzur's theorem. Thus, asymptotic states need to be manifestly and non-perturbatively gauge-invariant with respect to the el...

Can this also be used by others for #TalkCollapse, if not modified (and especially the source information visible)?

In fact, all observed physical elementary particles become effectively extended objects, a complete change of paradigm from quasi pointlike elementary particles.

If this can be eventually confirmed at experiment, this may change fundamentally how we think about particles.

You can find the background about this in my review arxiv.org/abs/1712.04721 - this 45 years-old prediction is entirely redefining what we think are physical particles in electroweak physics. It may be decisive for the next big collider, and perhaps even the current one, to take this into account.
Brout-Englert-Higgs physics: From foundations to phenomenology
The aim of this review is to describe the field-theoretical foundations of Brout-Englert-Higgs (BEH) physics, and to show how the usual phenomenology arises from it. This requires to give a precise an...

This supports the picture that physical particles are not the elementary ones, but need to be dressed by Higgs particles as bound states, without this changing their mass. This makes them extended objects. In theories different from the standard model, this can even alter the spectrum entirely.
