  "description": "<p>Using $\\left(27.12\u00b10.14\\right)\u00d7{10}^{8}$ $\\psi \\left(3686\\right)$ events collected with the BESIII detector, we present the first observation of the decays ${\\chi }_{cJ}\\to \\Lambda \\overline{\\Lambda }\\omega $, where $J=0$, 1, 2, with statistical significances of $11.7\\sigma $, $11.2\\sigma $, and $11.8\\sigma $. The branching fractions of these decays are determined to be $B\\left({\\chi }_{c0}\\to \\Lambda \\overline{\\Lambda }\\omega \\right)=\\phantom{\\rule{0ex}{0ex}}\\left(2.37\u00b10.22\u00b10.25\\right)\u00d7{10}^{-4}$, $B\\left({\\chi }_{c1}\\to \\Lambda \\overline{\\Lambda }\\omega \\right)=\\left(1.01\u00b10.10\u00b10.11\\right)\u00d7{10}^{-4}$, and $B\\left({\\chi }_{c2}\\to \\Lambda \\overline{\\Lambda }\\omega \\right)=\\phantom{\\rule{0ex}{0ex}}\\left(1.40\u00b10.13\u00b10.17\\right)\u00d7{10}^{-4}$, where the first uncertainties are statistical and the second are systematic. We observe no clear intermediate structures.</p>",
