  Evaluating the H(x, s; pp) scaling function of elastic proton-proton (pp)
collisions from recent TOTEM data at sqrt(s) = 8 TeV and comparing it with the
same function of elastic proton-antiproton (pp-) data of the D0 collaboration
at sqrt(s) = 1.96 TeV, we find, from this comparison alone, an at least 3.79
sigma {\signal} of Odderon exchange. If we combine this model independently
obtained result with that of a similar analysis but using TOTEM elastic pp
scattering data at sqrt(s) = 7 TeV, which resulted in an at least 6.26 {\sigma}
signal, the combined significance of Odderon exchange increases to at least
7.08 {\sigma}, model independently. Further combinations of various datasets in
the TeV energy range are detailed in the manuscript
