LetSk(N, χ) be the space of cusp forms of weightk, levelNand character χ. ForletL(s, sym2f) be the symmetric squareL-function andbe the Rankin–Selberg square attached tof. For fixedk≥ 2,Nprime, and real primitive χ, asymptotic formulas for the first and second moment of the central value ofL(s, sym2f) andover a basis ofSk(N, χ) are given asN→ ∞. As an application it is shown that a positive proportion of the central valuesL(1/2, sym2f) does not vanish.
