In physics, the pomeron is a Regge trajectory — a family of particles with increasing spin — postulated in 1961 to explain the slowly rising cross section of hadronic collisions at high energies. It is named after Isaak Pomeranchuk.

==Overview== While other trajectories lead to falling cross sections, the pomeron can lead to logarithmically rising cross sections — which, experimentally, are approximately constant ones. The identification of the pomeron and the prediction of its properties was a major success of the Regge theory of strong interaction phenomenology. In later years, a Balitsky–Fadin–Kuraev–Lipatov (BFKL) pomeron (named after Ian Balitsky, Victor Fadin, Eduard A. Kuraev and Lev Lipatov) was derived in further kinematic regimes from perturbative calculations in quantum chromodynamics (QCD), but its relationship to the pomeron seen in soft high energy scattering is still not fully understood.
