{"arxiv_id":"hep-ph/0506270","title":"Coupled-channel model for charmonium levels and an option for X(3872)","abstract":"The effects of charmed meson loops on the spectrum of charmonium are considered, with special attention paid to the levels above open-charm threshold. It is found that the coupling to charmed mesons generates a structure at the D \\bar{D}* threshold in the 1++ partial wave. The implications for the nature of the X(3872) state are discussed.","primary_cat":"hep-ph","cross_cats":[],"submitted_at":"2005-06-27T10:45:22+00:00","latest_version":1,"source":"arxiv","source_label":"arXiv","source_url":null,"has_pdf":true,"has_source":false,"verdict":"CONDITIONAL","confidence":"MODERATE","one_line_summary":"Coupling a bare 2 3P1 charmonium state to D Dbar* pairs generates a near-threshold virtual state with a D Dbar* scattering length near -8 fm, which the author offers as the origin of X(3872).","novelty_score":6.0,"correctness_risk":"medium","formal_verification":"none","upvotes":0,"downvotes":0,"pith_score":0.0,"inbound_count":22,"_links":{"html":"https://pith.science/paper/hep-ph/0506270","verdict":"/api/v1/verdicts/hep-ph/0506270"}}
