Abstract
We report a study of the process γγ→X→ηcπ+π-, where X stands for one of the resonances χc2(1P), ηc(2S), X(3872), X(3915), or χc2(2P). The analysis is performed with a data sample of 473.9fb-1 collected with the BABAR detector at the PEP-II asymmetric-energy electron-positron collider. We do not observe a significant signal for any channel, and calculate 90% confidence-level upper limits on the products of branching fractions and two-photon widths ΓX→γγB(X→ηcπ+π-): 15.7 eV for χc2(1P), 133 eV for ηc(2S), 11.1 eV for X(3872) (assuming it to be a spin-2 state), 16 eV for X(3915) (assuming it to be a spin-2 state), and 18 eV for χc2(2P). We also report upper limits on the ratios of branching fractions B(ηc(2S)→ηcπ+π-)/B(ηc(2S)→KS0K+π-)<10.0 and B(χc2(1P)→ηcπ+π-)/B(χc2(1P)→KS0K+π-)<32.9 at the 90% confidence level.
