We review a new technique for the calculation of two-loop amplitudes and discuss as an example the fermionic contributions to e + e − → q ¯ qg.

The two-loop electroweak bosonic correction to the muon lifetime is computed using methods of asymptotic expansion. Combined with previous calculations this completes the full two-loop correction to ∆r in the Standard Model.

The manifest expression for a (Virasoro-like) infinite-dimensional generalization of the 3 + 1-dimensional conformal algebra so(4, 2) is presented in this letter. It provides the arena for integrable models of Anti-de Sitter and conformal gauge theories of higher-generalized-spin fields in realistic dimensions.

We explore the deeply virtual Compton scattering process at NLO with the emphasis on the measurement of the tensor gluon skewed distributions. We recalculate the one-loop coefficient function and give two-loop results for anomalous dimensions and exclusive evolution kernels required for studying the logarithmic scaling violation. We evaluate weighted cross sections which give direct access to t...
