Isolating the relevant cut terms, we explain how the BFKL expansion can be used to construct the perturbative n-point MHV multi-Regge limit symbol from a finite number of basic building blocks. At three loops and at leading logarithmic order, two building blocks are required. These are extracted from the known three-loop six-point and seven-point symbols for general kinematics. The subleading and sub-subleading terms require two and one further building block, respectively. The latter could either be reconstructed from further perturbative data, or from BFKL integrals involving yet-unknown corrections to the central emission vertex, on whose construction we also briefly comment.}, keywords = {multi-Regge (autogen) / buildings (autogen) / BFKL equation (autogen) / scattering amplitude (autogen) / kinematics (autogen)}, cin = {T}, cid = {I:(DE-H253)T-20120731}, pnm = {611 - Fundamental Particles and Forces (POF3-611) / INTGAUGESTRING - Integrable Structures in Supersymmetric Gauge Theory and its String Dual (299865)}, pid = {G:(DE-HGF)POF3-611 / G:(EU-Grant)299865}, experiment = {EXP:(DE-MLZ)NOSPEC-20140101}, typ = {PUB:(DE-HGF)25 / PUB:(DE-HGF)29}, eprint = {1606.07640}, howpublished = {arXiv:1606.07640}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:1606.07640;\%\%$}, doi = {10.3204/PUBDB-2016-02553}, url = {https://bib-pubdb1.desy.de/record/300996}, }
