Dispersive analysis of the γγ⁎ → ππ process
We present a theoretical study of the γγ⁎→π+π−,π0π0 processes from the threshold through the f2(1270) region in the ππ invariant mass. We adopt the Omnès representation in order to account for rescattering effects in both s- and d-partial waves. For the description of the f0(980) resonance, we imple...
