Lev Nikolaevich Lipatov (Russian: Лев Никола́евич Липа́тов; born 2 May 1940, Leningrad)[1] is a Russian physicist, well known for his contributions to nuclear physics. He is the head of Theoretical Physics Division [2] at St. Petersburg's Nuclear Physics Institute of Russian Academy of Sciences in Gatchina. He is a corresponding member of Russian Academy of Sciences.
For the long period he worked with Professor Vladimir Gribov, laying a basis for a field theory description of deep inelastic scattering and annihilation (Gribov-Lipatov evolution equations, later known as DGLAP, 1972). He wrote significant papers of the Pomeranchuk singularity in Quantum chromodynamics (1977), contributed to the study of critical phenomena (semiclassical Lipatov's approximation), the theory of tunnelling and renormalon contribution to effective couplings.
