One-loop mass corrections of interacting string states
Lorenzo Grimaldi, Massimo Bianchi, Maurizio Firrotta
The free string spectrum is highly degenerate, with a degeneracy that grows exponentially with the mass. Turning on a non-vanishing string coupling introduces interactions, r…
Searching for Kerr in string amplitudes
Francesco Alessio, Paolo Di Vecchia, Maurizio Firrotta +1
We continue the approach of [1] to attempt to reproduce the classical electromagnetic current of the solution from the infinite-spin limit of a three-point a…
Scattering, Absorption and Emission of Highly Excited Strings
Maurizio Firrotta, Elias Kiritsis, Vasilis Niarchos
We study tree-level scattering processes of arbitrary string states using the DDF formalism and suitable coherent vertex operators. We obtain new exact compact formulae for heavy-h…
Veneziano and Shapiro-Virasoro amplitudes of arbitrarily excited strings
Maurizio Firrotta
We extend the Veneziano and Shapiro-Virasoro amplitudes to four arbitrarily excited states in bosonic string theory. We use the formalism of coherent string states based on the Di…
The chaotic emergence of thermalization in highly excited string decays
Maurizio Firrotta
We analyse the most general process of a generic highly excited string that decays into a less excited, yet generic, highly excited string emitting a tachyon. We provide a simple a…
Photon emission from an excited string
Maurizio Firrotta, Vladimir Rosenhaus
We compute the amplitude for an excited string in any precisely specified state to decay into another excited string in any precisely specified state, via emission of a tachyon or…
