Talk:Pati–Salam model

Composition
The composition link is ambiguous, however im not sure if this should just point to the wikitionary or be a link to an article?.--Wolfling 08:11, 18 October 2005 (UTC)

Leptons?
Does the SU(4)c include leptons as the fourth "color"? HEL 20:27, 19 October 2006 (UTC)
 * Yes. Just added to lead. --Michael C. Price talk 14:19, 18 June 2009 (UTC)

Intro and context
How about a little more introduction and context..

Possible defacement?
Is the "poopy" in the first statement a defacement? I certainly can't find such a technical term in any of my other study... (zben at umd.edu) —Preceding unsigned comment added by 129.2.135.72 (talk) 16:37, 2 June 2008 (UTC)


 * Yes, it is. Fixed now. Mjamja (talk) 20:15, 2 June 2008 (UTC)

Proton decay
I've added a link to the original Pati-Salam paper, Lepton number as the fourth "color". The article is presently completely incomprehensible, IMO, to anyone who does not already understand it. I was hoping I could make some small improvements, but I'm puzzled by some of the things in the original paper.

Pati/Salam say that B-L (which they call "fermion number") is preserved (although they define L as -L, so they call it B+L), but at the end of the paper they also say that the proton decays into three neutrinos and a pion:
 * {| border = 0

But this seems to violate B-L. Do they mean 2 anti-neutrinos and a neutrino, in addition to the pion?

 * || →  || 3   || +   ||
 * }

The paper is quite hard to read (e.g. they unaccountably switch the order of the muon and muon neutrino in their multiplets, which necessitates the insertion of a Pauli matrix into some of their gauge field matrices), but perhaps it will make more sense to someone here!--Michael C.

I suspect the original paper may be oudated. This might be more relevant: * Proton decay, annihilation or fusion? by Wu, Dan-Di; Li, Tie-Zhong, Zeitschrift für Physik C Particles and Fields, Volume 27, Issue 2, pp.321-323 preview Fusion of all three quarks is the only decay mechanism mediated by the Higgs particle, not the gauge bosons, in the Pati-Salam model. --Michael C.

Any testable predictions
Does this Pati–Salam model make any testable predictions, and how do they compare to those of the Georgi–Glashow SU(5) unification model ? - Rod57 (talk) 11:07, 22 September 2016 (UTC)
