We measured the branching fractions of the decays $$χ_{cJ} → Σ^–\bar{Σ}^+$$ for the first time using the final states $$n\bar{n}π^+π^–$$. The data sample exploited here is 448.1 × 10⁶ ψ (3686) events collected with BESIII. We find $$B(χ_{cJ} → Σ^–\bar{Σ}^+)$$ = (51.3 ± 2.4 ± 4.1) × 10^–5, (5.7 ± 1.4 ± 0.6 ) × 10^–5, and (4.4 ± 1.7 ± 0.5) × 10^–5, for $$\textit{J}$$ = 0, 1, 2, respectively, where the first uncertainties are statistical and the second systematic.
