Dependence of Deep Inelastic Structure Functions on Quark Masses
Protvino, 1998.- p.12, figs 3, tables 3, refs.:10.


We argue that the difference between the structure functions corresponding to deep inelastic scattering with and without heavy quarks in the current fragmentation region scales at high $Q^2$ and fixed (low) $x_{Bj}$. The lower bound on a charm contribution to the total structure function, $F_2^c(Q^2,x)$, is calculated and compared with the recent data on $F_2^c(Q^2,x)$ from H1 Collaboration.
