Elastic cross sections in an RSIIpscenario

Abstract

The elastic differential cross section is calculated at low energies (below 100 MeV) for the elements 3He, 20Ne, 40Ar, 14N, 12C, and for the 208Pb using a finite electromagnetic potential, which is obtained by considering a Randall–Sundrum II scenario modified by the inclusion of p compact extra-dimensions. The length scale is adjusted in the potential to compare with known experimental data and to set bounds for the parameter of the model. The effective four-dimensional (4D) electromagnetic potential is produced by a point charge, as seen from the three-brane that contains it, in uniform motion in an RSIIp scenario.

“…Here it is sufficient to consider the lowest partial waves ( 1 S 0 for I = 1 and 3 S 1 for I = 0). Finally to obtain the correct threshold behaviour we use effective range expansion for the S-wave np phase shifts: cot δ I = −1/(a I k) + r 0 I k/2, with a I=1 = −23.7 fm and r 0 I=1 = 2.76 fm for I = 1 [36], and a I=0 = 5.4194 fm and r 0 I=0 = 1.7536 fm [37]. We checked that the effective range expansion with the above parameters matches smoothly to SM16 analysis for E of about few MeV.…”
