{"arxiv_id":"hep-ph/0507062","title":"Four Quark Interpretation of Y(4260)","abstract":"We propose that the Y(4260) particle recently announced by BaBar is the first orbital excitation of a diquark-antidiquark state ([cs][cbar sbar]). Using parameters recently determined to describe the X(3872) and X(3940) we show that the Y mass is compatible with the orbital excitation picture. A crucial prediction is that Y(4260) should decay predominantly in D_s D_sbar. The Y(4260) should also be seen in B non-leptonic decays in association with one kaon. We consider the full nonet of related four-quark states and their predicted properties. Finally, we comment on a possible narrow resonance in the same channel.","primary_cat":"hep-ph","cross_cats":[],"submitted_at":"2005-07-05T17:56:56+00:00","latest_version":2,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"MODERATE","one_line_summary":"Y(4260) is proposed to be the first orbital excitation of a [cs][cbar sbar] diquark-antidiquark pair, with the testable prediction that it decays predominantly to D_s D_sbar.","novelty_score":6.0,"correctness_risk":"high","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0,"inbound_count":15,"_links":{"html":"https://pith.science/paper/hep-ph/0507062","verdict":"/api/v1/verdicts/hep-ph/0507062"}}
