Quantum chromodynamics studies at LEP2SUNANDA BANERJEE Tata Institute of Fundamental Research, Homi Bhabha Road, Mumbai 400 005, India Abstract. Several studies have been made to the hadronic final states in e+e- collisions at LEP. Studies of the annihilation process at LEP2 have given rise to results on jet rate, event shape, heavy flavour production, inclusive momentum spectra, Bose-Einstein correlation and colour reconnection effects. Event shape studies have given rise to accurate determination of the strong coupling constant as using O (as2) with resummed leading and next-to-leading log calculation and also with power law corrections. Studies of 2-photon processes have yielded results on gg cross-section, heavy flavour production, photon structure function and g*g* scattering. Keywords.
