Abstract

We consider the production of η_c and χ_cJ states recoiled with a photon upto O(αsv²) at BESIII and B-factories within the frame of NRQCD factorization. With the corrections, we revisit the numerical calculations to the cross sections for η_c(nS) and χ_cJ (mP) states. We argue that the search for XY Z states with even charge conjugation such as X(3872), X(3940), X(4160), and X(4350) recoiled with a photon at BESIII may help clarify the nature of these states. For completeness, the production of charmonium with even charge conjugation recoiled with a photon at B factories is also discussed.
