Family of particles-- Outlandish?[edit]

Somebody wrote that the definition of pomeron on this page, a Regge trajectory with particles lying on it, is "outlandish". Maybe it is sort of arguable, because I don't think that any actual particles are definitively established to be on the pomeron trajectory, but there are candidates. The problem, as I understand it, is that there is mixing between quark vacuum condensates and pure glue vacuum condensates, so that identifying a glueball is difficult. That's an unfortunate thing--- it makes the trajectory appear more mysterious than it would be in a pure glue world, where you would think that there would be clear spin 0, spin 2, spin 4, spin 6 particles etc. on the pomeron. But I don't think it's a lie to say what it says, even though it is a simplification, because it gets the main idea across. Perhaps there's a way to say it better.Likebox (talk) 19:20, 8 July 2008 (UTC)

...assuming only that the cross sections do not fall[edit]

Sorry, I don't understand "assuming only that the cross sections do not fall." Can someone rewrite this so it is clear to someone who does not have intimate knowledge of experimental particle physics? I cannot imagine how a cross section can fall. David Spector (talk) 23:56, 17 December 2011 (UTC)
