Description
There has been much recent progress towards extending the BFKL equation to next-to-next-to-leading logarithmic (NNLL) accuracy. In this talk I will briefly review the status of this programme of research. I will then discuss our recent progress in extracting some of the missing ingredients of the NNLL kernel, including the one-loop central-emission vertex (CEV) for two gluons which are not strongly ordered in rapidity. I will emphasise the non-trivial colour structure that remains after taking next-to-multi-Regge (NMRK) limits of one-loop amplitudes in QCD.
