Popis: We computed the deep inelastic scattering (DIS) structure functions F 2 ( x , Q 2 ) and F L ( x , Q 2 ) in the framework of Gribov–Levin–Ryskin–Mueller–Qiu, Zhu–Ruan–Shen (GLR–MQ–ZRS) equation. Both x and Q 2 evolutions of the structure functions are studied in the kinematic range of 1 0 − 6 ≤ x ≤ 1 0 − 2 and 5 ≤ Q 2 ≤ 100 G e V 2 respectively. we have suggested analytical solutions to the structure functions, our results are inspired by Regge like behaviour of gluons at small-x. The solutions of structure functions are obtained for two particular cases: (i) treating the strong coupling constant α s as an arbitrary constant, and (ii) considering the Q 2 dependency of α s . Our predicted results are in good agreement with the latest available high precision HERA data.
