We use dimensional regularization to calculate the O(ε2) expansion of all scalar one-loop one-, two-, three-, and four-point integrals that are needed in the calculation of hadronic heavy quark production. The Laurent series up to O(ε2) is needed as input to that part of the next-t...

Nonetheless, we would like to emphasize that the three eliminated contributions (Feynman diagrams with one-point scalar Feynman integrals, diagrams with internal EW gauge bosons and the wave-functions renormalization) must be included if the calculation is required to account also for subleading ...
We present general expressions for this particular class of two-loop graphs with one off-shell leg, and give explicit representations in terms of polylogarithms in the on-shell case. 展开 关键词: Scalar integrals Negative-dimension method Massless box integral ...
– 12 – The calculation (3.5) is the combination of two one-loop integrals, and so amounts to a two-loop correction to the Higgs mass. We should therefore consider other corrections at two-loop order. Totally generically, there is a two-loop Higgs mass correction due to electroweak gauge...
scalars and spin 1 fields. the matching allows to re-express the solutions of such equations in terms of simple one-loop master integrals in full generality, for any cft. 1.3 the search for asymptotic solutions for this reason, the search for asymptotic solutions of the cwi’s, which acquire...
