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…
