Do Quark Mass Effects Survive in the High-Q2Q^2 Limit of DIS?

preprint2002arXivOpen access

Abstract

Quark mass effects are analyzed at high Q2Q^2 in the current fragmentation region of DIS. It is found that the linear combination F2−2.75F2cF_2-2.75F^c_2 scales at large Q2Q^2 and small xx. We obtained a lower bound for the ratio F2c/F2F^c_2/F_2 which lies very close to the data from HERA.
