Heavy Flavour Production in Deep–Inelastic Scattering - Two–Loop Massive Operator Matrix Elements and Beyond
نویسنده
چکیده
We calculate the O(ε)–term of the two–loop massive operator matrix elements for twist 2–operators, which contribute to the heavy flavour Wilson coefficients in unpolarized deep–inelastic scattering in the asymptotic limit Q ≫ m. Our calculation was performed in Mellin space using Mellin– Barnes integrals and generalized hypergeometric functions. The O(ε)–term contributes in the renormalization at 3–loop order.

Two–Loop Massive Operator Matrix Elements for Unpolarized Heavy Flavor Production to O(ǫ)
We calculate the O(αs) massive operator matrix elements for the twist–2 operators, which contribute to the heavy flavor Wilson coefficients in unpolarized deeply inelastic scattering in the region Q2 ≫ m2, up to the O(ε) contributions. These terms contribute through the renormalization of the O(αs) heavy flavor Wilson coefficients of the structure function F2(x,Q 2). The calculation has been pe...

We calculate the O(αs) heavy flavor contributions to the Wilson coefficients of the structure function F2(x,Q 2) and the massive operator matrix elements (OMEs) for the twist–2 operators of unpolarized deeply inelastic scattering in the region Q2 ≫ m2. The massive Wilson coefficients are obtained as convolutions of massive OMEs and the known light flavor Wilson coefficients. We also compute the...

We calculate the logarithmic contributions to the massive Wilson coefficients for deep-inelastic scattering in the asymptotic region Q2 m2 to 3-loop order in the fixed flavor number scheme and present the corresponding expressions for the massive operator matrix elements needed in the variable flavor number scheme. Explicit expressions are given in Mellin N -space.
متن کاملDifference Equations in Massive Higher Order Calculations
The calculation of massive 2–loop operator matrix elements, required for the higher order Wilson coefficients for heavy flavor production in deeply inelastic scattering, leads to new types of multiple infinite sums over harmonic sums and related functions, which depend on the Mellin parameter N. We report on the solution of these sums through higher order difference equations using the summatio...
متن کاملEvaluating Two-Loop massive Operator Matrix Elements with Mellin-Barnes Integrals
The use of Mellin-Barnes integrals became a widespread technique for calculating Feynman diagrams throughout the last years [ 1], in particular to calculate double and triple box-diagrams. In Ref. [ 2], it was possible to expand the scalar two-loop two-point function in all orders in the dimensional regularization parameter ε, using additionally the gluing operation of Feynman diagrams, defined...
