Abstract
We describe the derived McKay correspondence for real reflection groups of rank in terms of a maximal resolution of the logarithmic pair consisting of the quotient variety and the discriminant divisor with coefficient . As an application, we verify a conjecture by Polishchuk and Van den Bergh on the existence of a certain semiorthgonal decomposition of the equivariant derived category into the derived categories of affine spaces for any real reflection group of rank .
