Relativistic diffusion in random gluon fields [PDF]
Z. HabaWe consider Wong equations for a particle with a continuous mass spectrum in a random Yang-Mills field approximating the quantum field at finite temperature. We show that particle time evolution can be approximated by a relativistic diffusion. Kubo's generator of the relativistic diffusion is defined as an expectation value of the square of the Liouville operator.View original: http://arxiv.org/abs/1104.0106
