Three flavours of Hybrid or π exhange: which is more attractive?
The paper says
“We show that signals φ(2175); Y(4260) and Υ(10890) in the \ssbar, ç and \bb share features that point to the possible role of π exchange forces between flavoured mesons generating effects that can mimic hybrid mesons.”

Abstract
This review summarises issues that have arisen since the appearance of "Rumsfeld Hadrons". We show that signals φ(2175); Y(4260) and Υ(10890) in the \ssbar, ç and \bb share features that point to the possible role of π exchange forces between flavoured mesons generating effects that can mimic hybrid mesons. The flavour dependence of these phenomena may help to resolve this question.
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. No sentence in this record was written by a model.
