Title: Search for Colour Reconnection Effects in e+e- -> WW -> hadrons through Multiplicity and Energy- and Particle-Flow Studies at sqrt(s) at or above 189 GeV. We report on preliminary studies of colour reconnection effects in hadronic decays of W pairs with the L3 detector at centre-of-mass energy at or above 189 GeV. The analysis is based on a comparison of charged particle multiplicities in qqqq and qqln events, and on the study of the particle and energy flow between jets associated to the same W boson and between two different W bosons in qqqq events. The interjet activity shows some sensitivity to hadronisation models incorporating colour reconnection schemes which are not excluded up to now from other studies.
