Title: Search for new decay modes of the ψ 2 ( 3823 ) and the process e + e − → π 0 π 0 ψ 2 ( 3823 )

Abstract

The decays ψ2(3823) → γχc0,1,2, π+ π– J/ψ, π0π0 J/ψ, ηJ/ψ, and π0J/ψ are searched for using the reaction e+e– → π+π– ψ2(3823) in a 19 fb–1 data sample collected at center-of-mass energies between 4.1 and 4.7 GeV with the BESIII detector. The process ψ2(3823) → γχc1 is observed in a 9 fb–1 data sample in the center-of-mass energy range 4.3–4.7 GeV, which confirms a previous observation but with a higher significance of 11.8σ, and evidence for ψ2(3823) → γχc2 is found with a significance of 3.2σ for the first time. The branching-fraction ratio $$\frac{B(ψ_{2}(3823)→γχ_{c2})}{B(ψ_{2}(3823)→γχ_{c1})}$$ is determined. No significant ψ2(3823) signals are observed for any of the other decay channels. Upper limits of branching-fraction ratios for ψ2(3823) → π+π– J/ψ, π0π0 J/ψ, η J/ψ, π0 J/ψ, γχc0 relative to ψ2(3823) → γχc1 are reported. The process e+e– → π0π0 ψ2(3823) is also searched for, and we find evidence for the process with a significance of 4.3σ. The average cross-section ratio $$\frac{σ(e^{+}e^{–} → π^{0}π^{0} ψ_{2}(3823))} {σ(e^{+}e^{–} → π^{+}π^{–} ψ_{2}(3823))}$$ is also determined.

abstractNote = {The decays ψ2(3823) → γχc0,1,2, π+ π– J/ψ, π0π0 J/ψ, ηJ/ψ, and π0J/ψ are searched for using the reaction e+e– → π+π– ψ2(3823) in a 19 fb–1 data sample collected at center-of-mass energies between 4.1 and 4.7 GeV with the BESIII detector. The process ψ2(3823) → γχc1 is observed in a 9 fb–1 data sample in the center-of-mass energy range 4.3–4.7 GeV, which confirms a previous observation but with a higher significance of 11.8σ, and evidence for ψ2(3823) → γχc2 is found with a significance of 3.2σ for the first time. The branching-fraction ratio $\frac{B(ψ_{2}(3823)→γχ_{c2})}{B(ψ_{2}(3823)→γχ_{c1})}$ is determined. No significant ψ2(3823) signals are observed for any of the other decay channels. Upper limits of branching-fraction ratios for ψ2(3823) → π+π– J/ψ, π0π0 J/ψ, η J/ψ, π0 J/ψ, γχc0 relative to ψ2(3823) → γχc1 are reported. The process e+e– → π0π0 ψ2(3823) is also searched for, and we find evidence for the process with a significance of 4.3σ. The average cross-section ratio $\frac{σ(e^{+}e^{–} → π^{0}π^{0} ψ_{2}(3823))} {σ(e^{+}e^{–} → π^{+}π^{–} ψ_{2}(3823))}$ is also determined.},
