{"arxiv_id":"1202.5088","title":"Probing scalar meson structures in $\\chi_{c1}$ decays into pseudoscalar and scalar","abstract":"We evaluate the decay branching ratios of $\\chi_{c1}\\to PS$, in a quark model parametrization scheme, where $P$ and $S$ stand for pseudoscalar and scalar meson, respectively. An interesting feature of this decay process is that the $c\\bar{c}$ annihilate via the pQCD hair-pin diagram is supposed to be dominant. Hence, this decay process should be sensitive to the quark components of the final-state light mesons, and would provide a great opportunity for testing the mixing relations among the scalar mesons, i.e. $f_0(1370)$, $f_0(1500)$ and $f_0(1710)$, by tagging the final state pseudoscalar mesons.","primary_cat":"hep-ph","cross_cats":["hep-ex"],"submitted_at":"2012-02-23T04:57:55+00:00","latest_version":2,"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,"inbound_count":0,"_links":{"html":"https://pith.science/paper/1202.5088","verdict":"/api/v1/verdicts/1202.5088"}}
