| Description: |
We present a new high-statistics measurement of the cross section for the process e+e-→e+e-π+π- at a center-of-mass energy of 29 GeV for invariant pion-pair masses M(π+π-) between 350 MeV/c2 and 1.6 GeV/c2. We observe the f2(1270) and measure its radiative width to be 3.15±0.04±0.39 keV. We also observe an enhancement in the π+π- spectrum near 1 GeV. General agreement is found with unitarized models of the γγ→π+π- reaction that include final-state interactions. |
