Differential cross sections in a thick brane world scenario

摘要

The elastic differential cross section is calculated at low energies for the elements He-3, Ne-20, Ar-40, N-14, C-12, and for Pb-208 using an effective 4D electromagnetic potential coming from the contribution of the massive Kaluza-Klein modes of the 5D vector field in a thick brane scenario. The length scale is adjusted in the potential to compare with known experimental data and to set bounds for the parameter of the model.
