Abstract
In this paper we obtain the heavyquark contribution to the longitudinal structure functions F L x Q 2 Since F L structure functions contains rather large heavy flavor contributions in the small x region we need to use the massive operator matrix elements which contribute to the heavy flavor Wilson coefficients in unpolarized deeply inelastic scattering in the region Q 2 m 2 The method of QCD analysis based on the Jacobi polynomials method is also described Our results for longitudinal structure function are in good agreement with the available experimental data
