The origin of the KLT relations and nonlinear relations for Yang-Mills amplitudes
Luiz Antonio Barreiro, Ricardo Medina
By means of a kinematic analysis of tree level graviton amplitudes we find, at least through six points, that the reason of their decompositon as a sum over products of Yang-Mills…
Graviton and gluon scattering from first principles
Rutger H. Boels, Ricardo Medina
Graviton and gluon scattering are studied from minimal physical assumptions such as Poincare and gauge symmetry as well as unitarity. The assumptions lead to an interesting and sur…
RNS derivation of N-point disk amplitudes from the revisited S-matrix approach
Luiz Antonio Barreiro, Ricardo Medina
In the past year, in arXiv:1208.6066 we proposed a revisited S-matrix approach to efficiently find the bosonic terms of the open superstring low energy effective lagrangian (OSLEEL…
Revisiting the S-matrix approach to the open superstring low energy effective lagrangian
Luiz Antonio Barreiro, Ricardo Medina
The conventional S-matrix approach to the (tree level) open string low energy effective lagrangian assumes that, in order to obtain all its bosonic order terms, it is nece…
Higher N-point Amplitudes in Open Superstring Theory
L. A. Barreiro, R. Medina
In this work we report on recent progress in the calculation of open superstring scattering amplitudes, at tree level, with more than four external massless states. We also report…
5-field terms in the open superstring effective action
Luiz Antonio Barreiro, Ricardo Medina
Some time ago the bosonic and fermionic 4-field terms of the non-abelian low energy effective action of the open superstring were obtained, to all order in . This was done at t…
