Measurement of the gamma gamma* --> eta and gamma gamma* --> eta' transition form factors

The BaBar Collaboration

Research output: Contribution to journalArticlepeer-review

Abstract

We study the reactions e+e- --> e+e- eta (eta') in the single-tag mode and measure the gamma gamma* --> eta (eta') transition form factors in the momentum transfer range from 4 to 40 GeV^2. The analysis is based on 469 fb-1 of integrated luminosity collected at PEP-II with the BABAR detector at e+e- center-of-mass energies near 10.6 GeV.
