Title: Observation of the Decay $X (3872) \to π^{0} χ_{c 1} (1 P)$

Abstract

Using a total of 9.0 fb^–1 of e⁺e^– collision data with center-of-mass energies between 4.15 and 4.30 GeV collected by the BESIII detector, we search for the processes e⁺e^– → γX(3872) with X(3872) → π⁰χ_cJ for J = 0,1,2. We report the first observation of X(3872) → π⁰χ_c1, a new decay mode of the X(3872), with a statistical significance of more than 5σ for all systematic fit variations. Normalizing to the previously established process e⁺e^– → γX(3872) with X(3872) → π⁺π^– J/ψ, we find B(X(3872) → π⁰χ_c1) / B(X(3872) → π⁺π^– J/ψ) = 0.8 8 + 0.33 – 0.27 ± 0.10 , where the first error is statistical and the second is systematic. We set 90% confidence level upper limits on the corresponding ratios for the decays to π⁰χ_c0 and π⁰χ_c2 of 19 and 1.1, respectively.

  abstractNote = {Using a total of 9.0 fb–1 of e+e– collision data with center-of-mass energies between 4.15 and 4.30 GeV collected by the BESIII detector, we search for the processes e+e– → γX(3872) with X(3872) → π0χcJ for J = 0,1,2. We report the first observation of X(3872) → π0χc1, a new decay mode of the X(3872), with a statistical significance of more than 5σ for all systematic fit variations. Normalizing to the previously established process e+e– → γX(3872) with X(3872) → π+π– J/ψ, we find B(X(3872) → π0χc1) / B(X(3872) → π+π– J/ψ) = 0.8 8 + 0.33 – 0.27 ± 0.10 , where the first error is statistical and the second is systematic. We set 90% confidence level upper limits on the corresponding ratios for the decays to π0χc0 and π0χc2 of 19 and 1.1, respectively.},
