Talk:Pati–Salam model

Composition[edit]

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)[reply]

Leptons?[edit]

Does the SU(4)_c include leptons as the fourth "color"? HEL 20:27, 19 October 2006 (UTC)[reply]

Yes. Just added to lead. --Michael C. Price ^talk 14:19, 18 June 2009 (UTC)[reply]

Intro and context[edit]

How about a little more introduction and context..

Possible defacement?[edit]

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)[reply]

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

Proton decay[edit]

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:

p

→

3
ν

+

π⁺

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

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[edit]

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)[reply]
