Talk:Seiberg duality

Confusion over baryons

I don't think it's clear what the statement, "The mesons and baryons are preserved by the duality," means. In particular, baryons in one theory are made of a different number of quarks than in the other theory. Does the statement just mean something like "both theories have mesons and baryons"? What is being preserved? — Preceding unsigned comment added by 198.128.206.157 (talk) 23:01, 11 January 2012 (UTC)[reply]

Baryons in one theory are made of Nc distinct quarks; there are thus Nf-choose-Nc baryons. Baryons in the other theory are made of Nf-Nc distinct quarks. There are thus Nf-choose-(Nf-Nc) baryons. The numbers match. More precisely the map between baryons maps a set of Nc flavours to the complement set of Nf-Nc flavours. — Preceding unsigned comment added by 73.10.164.58 (talk) 03:56, 11 June 2016 (UTC)[reply]
