The behavior of BH cross sections vs φ with Q2 is explored at three different values of the beam energy while keeping the values of xB at 0.343 and t at -0.172. The low, medium and high values of the beam energy used were respectively 3, 11 and 30 GeV. For each energy it was analized the region of Q2 values that allow to obtain valid and non-negative values of the cross sections. These ranges are summarized in Table 1. For medium and high k the same Q2 range was found.

Figure 1 displays the resulting distributions of the BH cross sections vs φ varying Q2 in the ranges shown on Table 1 using steps of 0.2 GeV2 for the low k and 0.45 GeV2 for the medium and high k.
