Differential cross sections in a thick brane world scenario

The elastic differential cross section is calculated at low energies for the elements3He,20Ne,40Ar,14N,12C, and for208Pb 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.
