Improved off-shell scattering amplitudes in string field theory and new computational methods

Abstract

We report on new results in Witten’s cubic string field theory for the off-shell factor in the 4-tachyon amplitude that was not fully obtained explicitly before. This is achieved by completing the derivation of the Veneziano formula in the Moyal star formulation of Witten’s string field theory ~MSFT!. We also demonstrate a detailed agreement of MSFT with a… (More)
