Quantum Chromodynamics

B. L. Ioffe is Head of the Laboratory of Theoretical Physics at ITEP, Moscow. He discovered the origin of baryon masses in QCD, the light-cone dominance in deep inelastic scattering. He predicted that parity violation in weak interactions should be accompanied by violation of charge symmetry or time reversal invariance, and the observation of parity violating spin-momentum correlations would mean the charge symmetry violation. He has won several prizes, including the Alexander von Humboldt Award. V. S. Fadin is Head of the Theoretical Department of the Budker Institute of Nuclear Physics. He is one of the authors of the BFKL equation for parton distributions, which gives the most common basis for the theoretical description of semi-hard processes. He is also one of the discoverers of the coherence effect in gluon emission, which is crucial for inclusive spectra of hadrons in their soft region. L. N. Lipatov is Director of the Theoretical Physics Department at the Institute for Nuclear Physics, St. Petersburg. Amongst his achievements he is one of the authors of the DGLAP and BFKL equations for the parton distributions used in the theoretical description of the deep-inelastic ep scattering and other processes in QCD. He has been awarded prizes from the ITEP and FIAN institutes for outstanding scientific achievements.
