Comparison of differential elastic cross sections in pp and ppbar collisions as evidence of the existence of the colourless C-odd three-gluon state

We describe a quantitative analysis to compare the ppbar elastic cross section as measured by the D0 collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sec...

description We describe a quantitative analysis to compare the ppbar elastic cross section as measured by the D0 collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections extrapolated to a center-of-mass energy of \sqrt s = 1.96 TeV are compared with the D0 measurement in the region of the diffractive minimum and second maximum of the pp cross section. The two data sets disagree at more than the 3σ level and thus provide evidence for t-channel exchange of a colorless C-odd three-gluon state in elastic scattering.
