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…
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 …
On-shell representation and further instances of the 2-split behavior of amplitudes
Thales Azevedo, Humberto Gomez, Renann Lipinski Jusinskas
The newly discovered splitting behavior of tree-level scattering amplitudes of particles and strings has been expressed in terms of currents containing one off-shell leg. In this w…
One-loop -point correlators in pure gravity
Humberto Gomez, Renann Lipinski Jusinskas, Cristhiam Lopez-Arcos +1
In this work we propose a simple algebraic recursion for the complete one-loop integrands of -graviton correlators. This formula automatically yields the correct symmetry factor…
