A field-inspired derivation of open string amplitudes
Humberto Gomez, Renann Lipinski Jusinskas, Sitender Pratap Kashyap
We propose a new method for computing -point tree-level open string amplitudes, inspired by the field-theoretical perturbiner framework and bypassing world-sheet moduli integrat…
Perturbiner methods in scattering amplitudes
Renann Lipinski Jusinskas
Berends--Giele currents have recently attracted renewed attention across the amplitude community, appearing in new contexts ranging from gravitational amplitudes to cosmological co…
On the amplitude expansion of gluon correlators in
Humberto Gomez, Renann Lipinski Jusinskas, Arthur Lipstein +1
We show that tree-level gluon correlators in admit a natural expansion in terms of flat-space scattering amplitudes at all multiplicities. In particular, every …
Tension between string amplitude prescriptions with presumed spacetime supersymmetry
Thales Azevedo, Alessandro Georgoudis, Renann Lipinski Jusinskas +1
We analyze an alternative prescription for computing tree level scattering amplitudes in the pure spinor superstring. Proposed by Berkovits, and inspired by an earlier work by Lee…
Four-dimensional spectrum generating algebra for the superstring
Renann Lipinski Jusinskas, Aravindhan Srinivasan
We derive the spectrum generating algebra for the hybrid string with manifest super Poincaré symmetry in . Our DDF operators e…
Perturbative Unitarity Calls for An Action
Subhroneel Chakrabarti, Renann Lipinski Jusinskas
In this work, we investigate the consistency of a perturbative definition of the S-matrix in a particular class of non-Lagrangian theories. We focus on the -form theories propos…
