Template talk:Flavour quantum numbers

message: The anomalies that break B and L individually cancel exactly to conserve B−L. See, for example, the end of the SM section of Phenomenological guide to physics beyond the Standard Model. In fact, you can (in Beyond-the-SM models) gauge the B−L symmetry. Of course, you can also break the symmetry in some SuSy models, but that's decidedly beyond-the-SM. -- Xerxes 18:25, 19 December 2005 (UTC)

message: This is more than just the flavour associated quantum numbers.  Perhaps we should rename it just "quantum numbers"? --Michael C. Price talk 23:27, 11 November 2008 (UTC)
replies: text: I split up the (baryonic) flavour quantum numbers from the others. This should solve your question. --Dogbert66 (talk) 09:30, 24 January 2011 (UTC)
thread_title: More than Flavour

message: Topness and weak isospin both are denoted by T. This is an ambiguosity like denoting bottomness and baryon number both by B. The latter was resolved in denoting bottomness by B' (sometimes B* used). Shouldn't we do the same for topness, i. e. using a T' as symbol? We could leave Tz aka T3 as it is. --ErnstS talk 12:55, 31 January 2009 (CET)
A better proposal might be to leave T as the sign for topness. Instead, we might use IW for weak isospin (just like YW for weak hypercharge) instead of the ambiguous T, and IW3 or IWz for its 3rd component (instead of T3 or Tz).--ErnstS talk 10:20, 19 February 2009 (CET)
:Yes IW for weak isospin make sense to me. The dashes are too easy to miss. --Michael C. Price talk 13:58, 19 February 2009 (UTC)
thread_title: Topness and Weak Isospin

message: This template uses Iz as a denotation for the 3rd component of isospin rather than I3 (same for weak isospin, currently Tz instead of T3). When I changed some articles in english and german WP I messed up with several Z-s (also used as index). These are:
1) z (lowercase) as denotation for the 3rd component instead of 3
2) Z (uppercase) for the Z Boson
3) z (lowercase) for dimensionless charge number, i.e. the charge measured in units of the elementary charge e. This is used if there is a need for disambiguation with the Charge Q = z • e . For atoms this is identical with the atomic number Z (uppercase).
Especially for discussion of the electroweak interaction couplings, all three z's mess up, terrible :-( ! German example: de:schwache Ladung
What do you think about using 3 instead of z for the 3rd component, i.e. I3 for 3rd component of isospin, T3 (or maybe IW3) as 3rd component of weak isospin?
Thanks in advance for any comments

replies: text: I like the idea of 3 instead of z.  Plus it seems more common in the literature.  Updated.--Michael C. Price talk 22:37, 1 November 2009 (UTC)

text: PS I looked in the literature and it seems to be choice between I3 & T3; I can't see z used as a subscript anywhere.  All my QFT books (Cheng & Li, Kaku, Itzykson & Zuber, Leite Lopes, Sterman) use either T3 or I3, not Tz or Iz. Nishijima's original paper uses I3. --Michael C. Price talk 00:39, 7 November 2009 (UTC)

message: On the wiki site for "Hypercharge"
it says Y = B + S - (C - B' + T)/3
while the template says
Y = (B + S + C + B′ + T)
