  "description": "<p>Decays ${\\chi }_{cJ}\\left(J=0,1,2\\right)\\to \\omega \\varphi $ are studied using $\\left(448.1\u00b12.9\\right)\u00d7{10}^{6}\\psi \\left(3686\\right)$ events collected with the BESIII detector in 2009 and 2012. In addition to the previously established ${\\chi }_{c0}\\to \\omega \\varphi $, the first observation of ${\\chi }_{c1}\\to \\omega \\varphi $ is reported in this paper. The measured product branching fractions are $B\\left(\\psi \\left(3686\\right)\\to \\gamma {\\chi }_{c0}\\right)\u00d7B\\left({\\chi }_{c0}\\to \\omega \\varphi \\right)=\\left(13.83\u00b10.70\u00b11.01\\right)\u00d7{10}^{-6}$ and $B\\left(\\psi \\left(3686\\right)\\to \\gamma {\\chi }_{c1}\\right)\u00d7B\\left({\\chi }_{c1}\\to \\omega \\varphi \\right)=\\phantom{\\rule{0ex}{0ex}}\\left(2.67\u00b10.31\u00b10.27\\right)\u00d7{10}^{-6}$, and the absolute branching fractions are $B\\left({\\chi }_{c0}\\to \\omega \\varphi \\right)=\\left(13.84\u00b10.70\u00b11.08\\right)\u00d7{10}^{-5}$ and $B\\left({\\chi }_{c1}\\to \\omega \\varphi \\right)=\\left(2.80\u00b10.32\u00b10.30\\right)\u00d7{10}^{-5}$. We also find strong evidence for ${\\chi }_{c2}\\to \\omega \\varphi $ with a statistical significance of $4.8\\sigma $, and the corresponding product and absolute branching fractions are measured to be $B\\left(\\psi \\left(3686\\right)\\to \\gamma {\\chi }_{c2}\\right)\u00d7B\\left({\\chi }_{c2}\\to \\omega \\varphi \\right)=\\left(0.91\u00b10.23\u00b10.12\\right)\u00d7{10}^{-6}$ and $B\\left({\\chi }_{c2}\\to \\omega \\varphi \\right)=\\left(1.00\u00b10.25\u00b10.14\\right)\u00d7{10}^{-5}$. Here, the first errors are statistical and the second ones systematic.</p>",
