Beyond minimal standard model.

Click For Summary
The discussion centers on exploring Higgs models beyond the minimal standard model, with a focus on particle spectra predictions derived from Lamb's balance. Key predicted masses include 68 GeV for H+, 115 GeV for a potential Higgs, and 175 GeV possibly related to the top quark, with 246 GeV aligning with the electroweak Higgs field scale. The conversation questions whether these spectra align with supersymmetry (SUSY) models, particularly regarding the degeneracy at 175 GeV and the implications of a two doublets Higgs model. The possibility of alternative models, such as triplet Higgs or two doublets plus singlet configurations, is also considered, alongside the validity of predicting a 45-49 GeV particle. The thread concludes with a reference to a working paper uploaded by Alejandro for further insights.

Has anyone got good pointed in higgs models beyond the minimal? The PDG review is too small for my taste.

From Lamb's balance, I am getting the prediction of the following particle spectra

68 GeV. According L3, it could be H+
Z0 as usual, and W+ as usual, almost
115 GeV. According ALEPH, it could be any Higgs
175 GeV. Degenerated with Top mass? Or just the Top, no new boson after all
246 GeV. It coincides with the EW higgs field scale in the minimal model, but it should appear physically, thus as a particle.

Does this spectrum fit with some SUSY model, using the degeneracy at 175? For complete SUSY breaking, I believe it does not fit because H+ is lower than Z0.

A two doublets higgs model is enough for this spectrum, but is it unique? What about using triplet higgs, or two doublets plus singlet, Zee model etc? I am no risking a predition for a 45-49 GeV particle because it is weaker than the others (and I believe the Z0 experiments have already completely disproved this possibility, am I right here?), but I could try it if it results good for a triplet model or similar.

Just a fast note; I have uploaded in my website the working copy of the http://dftuz.unizar.es/%7Erivero/research/LS9530.pdf about this.

Thread 'Some words on neutrino physics?'

Hi everyone, I am doing a final project on the title " fundamentals of neutrino physics". I wanted to raise some issues with neutrino which makes it the possible way to the physics beyond standard model. I am myself doing some research on these topics but at some points the math bugs me out. Anyway, i have some questions which answers themselves confounded me due to the complicated math. Some pf them are: 1. Why wouldn't there be a mirror image of a neutrino? Is it because they are...
