Abstract

We establish the group-theoretic classification of Sato-Tate groups of\nself-dual motives of weight 3 with rational coefficients and Hodge numbers\nh3,0 = h2,1 = h1,2 = h0,3 = 1. We then describe families of motives\nthat realize some of these Sato-Tate groups, and provide numerical evidence\nsupporting equidistribution. One of these families arises in the middle\ncohomology of certain Calabi-Yau threefolds appearing in the Dwork quintic\npencil; for motives in this family, our evidence suggests that the Sato-Tate\ngroup is always equal to the full unitary symplectic group USp(4).
