Is the Z2xZ2-graded sine-Gordon equation integrable?Bruce, Andrew ![]() in Nuclear Physics B (2021), 971 We examine the question of the integrability of the recently defined Z2xZ2-graded sine-Gordon model, which is a natural generalisation of the supersymmetric sine-Gordon equation.

[more ▼] We examine the question of the integrability of the recently defined Z2xZ2-graded sine-Gordon model, which is a natural generalisation of the supersymmetric sine-Gordon equation. We do this via appropriate auto-Bäcklund transformations, construction of conserved spinor-valued currents and a pair of infinite sets of conservation laws.

[more ▼] We present the computation of the direct photon production cross-section in perturbative QCD to all orders in the limit of high partonic center-of-mass energy. We show how the high-energy resummation can be performed consistently in the presence of a collinear singularity in the final state, we compare our results to the fixed order NLO cross-section in MS scheme, and we provide predictions at NNLO and beyond.
