We obtain the noncommutative extension of the Hu-Paz-Zhang master equation for a Brownian particle linearly coupled to a bath of harmonic oscillators. We consider the particular case of an Ohmic regime.6 pages, Latex file, Presented by J.N.Prata at the Workshop on Advances in Foundations of Quantum Mechanics and Quantum Information with atoms and photons, 2-5 May 2006, Turin, ItalyHigh Energy Physics - Theorytext
