Abstract
The predictions were done for asymmetry between production spectra of Lambda^0 and antiLambda^0 at the energy of LHC experiments. The value of A(s) should be situated in the band between two curves that are calculated in Quark-Gluon String Model with two possible values of intercept alpha_{SJ}(0)=0,5 and 0,9. Both curves describe the asymmetries measured at lower energies up to RHIC experiments. The data of H1 experiment can be fitted only with alpha_{SJ}(0)=0,9.
