Sato–Tate distributions and Galois endomorphism modules in genus 2 by Kedlaya, Kiran S., Sutherland, Andrew Victor, Fite, Francesc, Rotger, Victor

“…We then classify A according to the Galois module structure on the ℝ-algebra generated by endomorphisms of [superscript A][line over Q] (the Galois type), and establish a matching with the classification of Sato–Tate groups; this shows that there are at most 52 groups up to conjugacy which occur as Sato–Tate groups for suitable A and k, of which 34 can occur for k=ℚ. …”
