For α β − 1 0, we obtain two-sided inequalities for the moment integral I(α, β) = ∫ℝ|x|−β|sinx|α dx. These are then used to give the exact asymptotic behavior of the integral as α → ∞. The case I(α, α) corresponds to the asymptotics of Ball’s inequality, and I(α, [α]−1) corresponds to a kind of novel “oscillatory” behavior.
