Abstract

Close
- Decays chi(cJ)(J = 0, 1, 2) -> omega phi are studied using (448.1 +/- 2.9) x 10(6)psi(3686) events collected with the BESIII detector in 2009 and 2012. In addition to the previously established chi(c0) -> omega phi, the first observation of chi(c1) -> omega phi is reported in this paper. The measured product branching fractions are B(psi(3686) -> gamma chi(c0)) x B(chi(c0) -> omega phi) = (13.83 +/- 0.70 +/- 1.01) x 10(-6) and B(psi(3686) -> gamma chi(c1)) x B(chi(c1) -> omega phi) = (2.67 +/- 0.31 +/- 0.27) x 10(-6), and the absolute branching fractions are B(chi(c0) -> omega phi) = (13.84 +/- 0.70 +/- 1.08) x 10(-5) and B(chi(c1) -> omega phi) = (2.80 +/- 0.32 +/- 0.30) x 10(-5). We also find strong evidence for chi(c2) -> omega phi with a statistical significance of 4.8 sigma, and the corresponding product and absolute branching fractions are measured to he B(psi(3686) -> gamma chi(c2)) x B(chi(c2) -> omega phi) = (0.91 +/- 0.23 +/- 0.12) x 10(-6) and B(chi(c2) -> omega phi) = (1.00 +/- 0.25 +/- 0.14) x 10(-5). Here, the first errors are statistical and the second ones systematic.
