NGAMMA: A Monte Carlo generator for multiphoton production in $e^{+} e^{-}$ annihilation

L. V. Kardapoltsev, N. A. Melnikova

We present the NGAMMA Monte Carlo event generator for QED processes of $e^{+} e^{-}$ annihilation into a multiphoton final state, $e^{+} e^{-} \to N I^^{3} (N \geq 2)$ . These processes are an import…
