We propose a method to produce precise Monte Carlo estimates of
multi-scale multi-loop integrals directly in Minkowski space without an
explicit contour deformation. The validity of our strategy is
corroborated by presenting several examples ranging from one to three
loops. When used in connection with four-dimensional regularization
techniques, our treatment can be extended to ultraviolet and infrared
divergent integrals.
