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…
Can the Dirac deltas in dipole fields be ignored in classical interactions?
Thales Azevedo
When studying (or teaching) classical electromagnetism, one is bound to deal with the electric field of an ideal electric dipole, as well as its magnetic counterpart. A careful ana…
Compton scattering from superstrings
Thales Azevedo, Daniel E. A. Matamoros, Gabriel Menezes
We propose a candidate Compton amplitude which is valid for any (integer) quantum spin and free from any spurious poles. We consider the cases of electromagnetism and gravity. We o…
Space pirates: a pursuit curve problem involving retarded time
Thales Azevedo, Anderson Pelluso
We revisit the classical pursuit curve problem solved by Pierre Bouguer in the 18th century, taking into account that information propagates at a finite speed. To a certain extent,…
Bosonic sectorized strings and the theory
Thales Azevedo, Renann Lipinski Jusinskas, Matheus Lize
In this work, we investigate the bosonic chiral string in the sectorized interpretation, computing its spectrum, kinetic action and -point amplitudes. As expected, the bosonic a…
Heterotic and bosonic string amplitudes via field theory
Thales Azevedo, Marco Chiodaroli, Henrik Johansson +1
Previous work has shown that massless tree amplitudes of the type I and IIA/B superstrings can be dramatically simplified by expressing them as double copies between field-theory a…
Connecting the ambitwistor and the sectorized heterotic strings
Thales Azevedo, Renann Lipinski Jusinskas
The sectorized description of the (chiral) heterotic string using pure spinors has been misleadingly viewed as an infinite tension string. One evidence for this fact comes from the…
Ambitwistor formulations of gravity and gauge theories
Thales Azevedo, Oluf Tang Engelund
We consider -dimensional amplitudes in gravities (conformal gravity in ) and in the recently introduced gauge theory, from the perspective of the CHY formula…
Background constraints in the infinite tension limit of the heterotic string
Thales Azevedo, Renann Lipinski Jusinskas
In this work we investigate the classical constraints imposed on the supergravity and super Yang-Mills backgrounds in the limit of the heterotic string using the pure spi…
On the = 4, d = 4 pure spinor measure factor
Thales Azevedo
In this work, we obtain a simple measure factor for the and zero-mode integrations in the pure-spinor formalism in the context of an = 4, d = 4 theory. We sho…
Open-closed superstring amplitudes using vertex operators in
Thales Azevedo, Nathan Berkovits
Using the pure spinor formalism, a particular superstring scattering amplitude involving one closed string and open string vertex operators in $\mathrm{AdS}{}_5 \times \mathrm{…
