String Memories ... openly retold
Alice Aldi, Massimo Bianchi, Maurizio Firrotta
We identify string corrections to the EM memory effect. Though largely negligible in the low-energy limit, the effect become relevant in high-energy collisions and in extreme event…

Closed superstring moduli tree-level two-point scattering amplitudes in Type IIB orientifold on
Alice Aldi, Maurizio Firrotta
We reconsider the two-point string scattering amplitudes of massless Neveu-Schwarz--Neveu-Schwarz states of Type IIB orientifold superstring theory on the disk and projective plane…

String coherent vertex operators of Neveu-Schwarz and Ramond states
Alice Aldi, Maurizio Firrotta
We present a compact expression for a coherent vertex operator in superstring theory, in the Neveu-Schwarz sector, that can be easily extended to the Ramond sector by supersymmetri…
