Double Logarithmic Terms ln2x in the Heavy Quark Production \sigma (P\bar P \rightarrow h\bar h) - \sigma (PP \rightarrow h\bar h) Cross Sections

Dorota Kotlorz, Andrzej Kotlorz

Predictions for the difference of proton--antiproton and proton--proton cross sections in the heavy quark production within LO DGLAP analysis together with the ln2x  terms resummation are presented. An important role of the double logarithmic ln2x corrections in a case of the large rapidity gap between a quark and an antiquark is discussed.
