Our proof relies on relating the class group L-functions to Eisenstein series evaluated at Heegner points using formulas due to Hecke. The main technical contribution is the uniform sup norm bound for Eisenstein series E(z, 1/2 + it) ≪ε y1/2(|t| + 1)1/3+ε, y ≫ 1, extending work of Blomer and Titchmarsh.
