Calculating Three Loop Ladder and V-Topologies for Massive Operator Matrix Elements by Computer Algebra
Three loop ladder and V-topology diagrams contributing to the massive operator matrix element AQg are calculated. The corresponding objects can all be expressed in terms of nested sums and recurrences depending on the Mellin variable N and the dimensional parameter ε. Given these representations, the desired Laurent series expansions in ε can be obtained with the help of our computer algebra to...
متن کاملGluonic Massive Operator Matrix Elements
The O(αsnfT 2 FCA,F ) terms to the massive gluonic operator matrix elements are calculated for general values of the Mellin variable N using a new summation technique. These twist-2 matrix elements occur as transition functions in the variable flavor number scheme at NNLO. The calculation uses sum-representations in generalized hypergeometric series turning into harmonic sums. The analytic cont...
متن کاملTwo-loop Massive Fermionic Operator Matrix Elements and Intial State Qed Corrections to E Two-loop Massive Fermionic Operator Matrix Elements
We describe the calculation of the two–loop massive operator matrix elements for massive external fermions. These matrix elements are needed for the calculation of the O(α 2) initial state radiative corrections to e + e − annihilation into a neutral virtual gauge boson, based on the renor-malization group technique.
متن کاملTwo–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...
متن کاملHeavy Flavour Production in Deep–Inelastic Scattering - Two–Loop Massive Operator Matrix Elements and Beyond
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 ...
