Measurement of the γγ∗→η and γγ∗→η′ transition form factors

We study the reactions e + e − → e + e − η ( ' ) in the single-tag mode and measure the γ γ ∗ → η ( ' ) 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 +...

Description
Summary:We study the reactions e + e − → e + e − η ( ' ) in the single-tag mode and measure the γ γ ∗ → η ( ' ) 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.
