Investigating the exclusive protoproduction of dileptons at high energies
M. V. T. Machado
Using the high energy color dipole approach, we study the exclusive photoproduction of lepton pairs. We use simple models for the elementary dipole-hadron scattering amplitude that…

An extension of the Linear Delta Expansion to Superspace
M. C. B. Abdalla, J. A. Helayël-Neto, Daniel L. Nedel +1
We introduce and discuss the method of Linear Delta Expansion for the calculation of effective potentials in superspace, by adopting the improved version of the super-Feynman rules…

Observer dependent D-brane for strings propagating in pp-wave time dependent background
Dafni Z. Marchioro, Daniel L. Nedel
We study type IIB superstring in the pp-wave time-dependent background, which has a singularity at . We show that this background can provide a toy model to study some ideas r…
