B'

I can't say I've ever seen it put like this. I've only ever seen bottomness denoted as a B with a tilde (~) over it to distinguish it from the baryon number. Is there any particular reason for it being written like this here or should it be changed?

It's probably because B tilde is impossible (or very hard) to write in plain text. B prime's a working alternative.Headbomb {^ταλκ_{κοντριβς} – WP Physics} 11:57, 16 March 2009 (UTC)[reply]

Is it actually used anywhere? In all the listings I've seen, bottomness is given as B. Using B' as a 'working alternative' is original research. — MK (^t/_c) 19:08, 20 November 2011 (UTC)[reply]

bottomness of −1

In a book where they still called it Beauty I read that it's default value were +1. I could also verify it with the Gell-Mann-Nishijima Formula. The Example was the positive charged B-Meson B⁺ which is a compound made of u-quark and anti-b-quark. According to my Materials B⁺-Meson got no B (for not being a Baryon) S=C=T=0 ,Q=+1 and I₃=+0.5 which leads to the expression Q=I₃+(B+S+C+B'+T)*0.5 <=> +1=B'. Does anyone got contradictory information to this? If not,we would have to correct the article. —Preceding unsigned comment added by Brubbler (talk • contribs) 19:44, 15 March 2009 (UTC)[reply]

Bottomness is -1 for bottom quarks and +1 for bottom antiquarks. B⁺ mesons are u
b
, therefore have bottomness +1. What's there to correct?Headbomb {^ταλκ_{κοντριβς} – WP Physics} 20:36, 15 March 2009 (UTC)[reply]

Sorry, I see you're right. I just wrote this in the hassle of confusion by what was written in the book.
