All DDF/lightcone two-particle decay widths up to level in open bosonic string in critical dimension
Samuele Critelli, Igor Pesando
We carry out an ``experimental analysis'' in which we explicitly compute all possible Abelian two-particle decay channels (excluding the tachyon) of open bosonic massive states up…
Classical strings and the double copy
Riccardo Morieri, Igor Pesando, Michael L. Reichenberg Ashby +1
The double copy is by now a well-established relationship between scattering amplitudes and classical solutions in gauge and gravity (field) theories, and is itself inspired by amp…
Bosonic string massive scalar amplitudes and absence of "chaos''
Igor Pesando
We compute directly in covariant formalism various four point massive scalar amplitudes in bosonic string with scalars up to level 11. The most ``difficult'' amplitude we consider…
DDF amplitudes are lightcone amplitudes and the naturalness of Mandelstam map
Dripto Biswas, Igor Pesando
We show that on shell DDF amplitudes are on shell lightcone amplitudes and that Mandelstam maps emerge naturally with a precise normalization and are intrinsic to the DDF states. O…
The Reggeon Vertex for DDF States
Dripto Biswas, Raffaele Marotta, Igor Pesando
We provide a compact expression for the generating function of correlators involving an arbitrary number of bosonic open string DDF states. The explicit correlators for DDF sta…
The bosonic string spectrum and the explicit states up to level from the lightcone and the chaotic behavior of certain string amplitudes
Igor Pesando
We compute the irreps and their multiplicities of bosonic string spectrum up to level 10 and we give explicitly the on shell lightcone states which make the irreps. For scalars and…
Framed DDF operators and the general solution to Virasoro constraints
Dripto Biswas, Igor Pesando
We define the framed DDF operators by introducing the concept of local frames in the usual formulation of DDF operators. In doing so it is possible to completely decouple the DDF o…
On the Quantization of the GS Type IIB Superstring Action on AdS3 X S3 with NSNS flux
I. Pesando
We quantize the type IIB GS string action on AdS3 X S3 with pure NSNS background and we show that it is equivalent to Liouville with periodic boundary condition plus free spacetime…
A k Gauge Fixed Type IIB Superstring Action on AdS_{5} X S_{5}
I. Pesando
We describe the type IIB supergravity background on AdS_{5} X S_{5} using the potentials of AdS_{5|4} X S_{5} and we use the supersolvable algebra associated to AdS_{5|4} to comput…
