Vortical susceptibility of finitedensity QCD matter
Here, the susceptibility of finitedensity QCD matter to vorticity is introduced, as an analog of magnetic susceptibility. It describes the spin polarization of quarks and antiquarks in finitedensity QCD matter induced by rotation. We estimate this quantity in the chirally broken phase using the mixed gaugegravity anomaly at finite baryon density. It is proposed that the vortical susceptibility of QCD matter is responsible for the polarization of Λ and Λ¯ hyperons observed recently in heavy ion collisions at RHIC by the STAR collaboration.
