It is shown how high-order cumulants of net-charge distribution in hadronic collisions at LHC energies can be expressed via lower-order terms under the assumption that particle-antiparticle pairs are produced independent local processes. argued and tested with HIJING model this typically valid for net-proton fluctuations case when no critical behaviour present system. Values estimated such a wa...

We present results for the $gg$-part of one-loop corrections to recently introduced "topological charge" GPD $\widetilde F(x,q^2)$. In particular, we give expression its evolution kernel. To enforce strict compliance with gauge invariance requirements, have used on-shell states external gluons, and obtained identical both in Feynman light-cone gauges. No "zero mode" $\delta (x)$ terms were foun...
