Hint for a minimal interaction length in $e^{+}{e}^{-}\to \gamma \gamma$ annihilation in total cross section of centre-of-mass energies 55-207 GeV

Yutao Chen, Minghui Liu, Jürgen Ulbricht

The measurements of the total cross section of the $e^{+}{e}^{-}\to \gamma \gamma$ reaction from the VENUS, TOPAS, OPAL, DELPHI, ALEPH and L3 collaborations, collected between 1989 to 2003, are use…
