High-energy scattering often demands resumming large energy logarithms, beyond the reach of fixed-order QCD. Inspired by the old multiperipheral models, we study proton–proton collisions with a forward jet, a backward jet, and central mini-jets, using the BFKL framework. Jet rapidity distributions are used to search for BFKL effects, comparing PYTHIA8 predictions with those from the BFKLex Monte Carlo.
