On the behaviour of dis structure function ratio R(x, Q2) at small x
Kotikov A.V.
The behaviour of deep inelastic structure functions is studied at small χ in the leading and next-to-leading orders of perturbation theory. The scheme-invariant analysis for the longitudinal and transverse structure functions ratio R(x, Q2), is given. It is found that this ratio tends to zero asymptotically when χ —♦ 0.
