Title: Observation of e + e - γ χ c 1 and search for e + e - γ χ c 0 , γ χ c 2 , and γ η c at s near 10.6 GeV at Belle

Abstract

Using data samples of 89.5 fb -1, 711.0 fb -1, and 121.4 fb -1 collected with the Belle detector at the KEKB asymmetric-energy e +e - collider at center-of-mass energies 10.52 GeV, 10.58 GeV,and 10.867 GeV, respectively, we study the exclusive reactions e +e - → γχ cj (J = 0, 1, 2) and e +e -→ γη c. A significant γχ c1 signal is observed for the first time at cJ s = 10.58 GeV with a significance of 5.1σ including systematic uncertainties. No significant excesses for γχ c0, γχ c2, and γη c final states are found, and we set 90% credibility level upper limits on the Born cross sections (σ B) at 10.52 GeV, 10.58 GeV, and 10.867 GeV. Together with cross sections measured by BESIII-+at lower center-of-mass energies, the energy dependency of σ B(e + e - → γχ c1 ) is obtained.
