Experimental evidences of difference in $pp$ and $p\bar{p}$ interactions at high energies

Hadrons production is different in $p\bar{p}$ and $pp$ interactions at high energies. There is process of hadrons production from three quark strings in $p\bar{p}$ which is absent in $pp$. This process grows as $(\ln\sqrt{s})^2$ and becomes significant when energy of collision increases. Inclusive cross sections of $p\bar{p}$ interaction exceed inclusive cross sections of $pp$. Theoretical estimation of the ratio of $p\bar{p}$ to $pp$ at energy $\sqrt{s}=900$ GeV gives $R=1.12\pm0.03$. The UA1 data on $p\bar{p}$ transverse momentum distribution are about 1.2 -- 1.3 times higher than the CMS, ATLAS and ALICE data on $pp$ at energy $\sqrt{s}=900$ GeV.
