All-multiplicity monodromy and KLT relations for AdS string integrals

Maria Nocchi, Rodrigo Schmidt Pitombo, Aurélie Strömholm Sangaré +1

We propose and study all-multiplicity building blocks for tree-level string amplitudes in AdS. These are worldsheet integrals obtained by dressing the corresponding flat-space disc…

Monodromy Relations for String Amplitudes on AdS

Luis F. Alday, Rodrigo S. Pitombo, Aurélie Strömholm Sangaré

We consider the Veneziano amplitude describing the scattering of four gluons in type IIB string theory on . We propose a set of powerful monodromy relations…

Simplicity of Mellin amplitudes for AdSS

F. Aprile, C. Behan, R. S. Pitombo +1

The spectrum of half-BPS single-particle operators of the D1-D5 system in the supergravity regime is dual to the spectrum of Kaluza-Klein modes of tensor and graviton multiplets in…

Mellin amplitudes for

Connor Behan, Rodrigo S. Pitombo

There are holographic superconformal theories in all dimensions between two and six which allow arbitrary tree-level four-point functions to be fixed by basic consistency condition…

4D Chern-Simons and the pure spinor superstring

Nathan Berkovits, Rodrigo S. Pitombo

Four-dimensional Chern-Simons (4DCS) theory is useful for understanding integrable sigma-models and constructing new ones. In this paper, we show how to derive the complete pure sp…

Periodic strings: a mechanical analogy to photonic and phononic crystals

R. S. Pitombo, M. Vasconcellos, P. P. Abrantes +3

We study a periodic vibrating string composed of a finite sequence of string segments connected periodically, with each segment characterized by a constant linear mass density. The…
