{"arxiv_id":"0801.2646","title":"Three flavours of Hybrid or $\\pi$ exhange: which is more attractive?","abstract":"This review summarises issues that have arisen since the appearance of \"Rumsfeld Hadrons\". We show that signals $\\phi(2175)$; Y(4260) and $\\Upsilon(10890)$ in the \\ssbar, \\cc and \\bb share features that point to the possible role of $\\pi$ exchange forces between flavoured mesons generating effects that can mimic hybrid mesons. The flavour dependence of these phenomena may help to resolve this question.","primary_cat":"hep-ph","cross_cats":["hep-ex"],"submitted_at":"2008-01-17T11:00:42+00:00","latest_version":1,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":null,"confidence":null,"one_line_summary":null,"novelty_score":null,"correctness_risk":null,"formal_verification":null,"upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":3,"_links":{"html":"https://pith.science/paper/0801.2646","verdict":"/api/v1/verdicts/0801.2646"}}
