Stephan Narison is a Malagasy theoretical high-energy physicist specialized in quantum chromodynamics (QCD), the gauge theory of strong interactions. He is the founder of the Series of International Conferences in Quantum Chromodynamics (QCD-Montpellier) and of the Series of International Conferences in High-Energy Physics (HEPMAD-Madagascar).

He works on QCD spectral sum rules (QSSR) or SVZ sum rules which have been introduced by M.A. Shifman, A.I. Vainshtein and V.I. Zakahrov[1] for studying the non-perturbative dynamics of hadrons.

Scientific contributionsEdit

Among his various publications (237 papers as of January 2014), his most famous work is the first determination of the QCD coupling αs from hadronic heavy lepton τ-decays[2] where the running of αs from the τ-mass until the Z-boson mass demonstrates its 1/log Q^2 behavior predicted by asymptotic freedom.

He has contributed to the definition of the running and invariant quark masses in QCD[3] and on the tests of the gluonium/glueball nature of the scalar meson σ/f0(500) using QSSR,[4] ππ and γγ scatterings data.[5] His important estimates of the light[6] and heavy[7] quark masses and leptonic heavy-light mesons decay constants[8] are compiled in the Particle Data Group (PDG).[9]

He has also contributed to the QCD U(1) anomaly effect in the spin of the proton[10] and on the parametrization of the non-calculated higher order terms of the perturbative series in terms of the square of the tachyonic gluon mass not included in the standard Wilson Operator Product Expansion (OPE).[11]

He has contributed to the estimation of the hadronic contribution to the muon anomalous magnetic moment aμ=(gμ-2)/2.[12]
