Four-point amplitudes in N = 2 SCQCD / M. Leoni, A. Mauri, A. Santambrogio. - In: JOURNAL OF HIGH ENERGY PHYSICS. - ISSN 1029-8479. - 2014:9(2014 Sep), pp. 017.1-017.33. [10.1007/JHEP09(2014)017]
Abstract:
We compute four-point scattering amplitudes in N = 2 SCQCD with general external matter configurations using N = 1 superspace Feynman diagrams, at one loop in the general case and up to two loops in the fundamental sector. In the pure adjoint sector at one loop we confirm exact agreement with the corresponding amplitudes in N = 4 SYM theory, supporting the idea that a closed subsector of the SCQCD might be exactly integrable. External matter in the fundamental representation breaks dual conformal invariance already at one-loop order while the principle of maximal transcendentality is respected up to two loops.
