Letgbe a primitive holomorphic or Maass newform for. In this paper, by studying the Bessel integrals associated withg, we prove an asymptotic Besselδ-identity associated withg. Among other applications, we prove the following hybrid subconvexity bound $$\begin{eqnarray*} L\left(1/2+it,g\otimes \chi\right)\ll_{g,\varepsilon} (q(1+|t|))^{\varepsilon}q^{3/8}(1+|t|)^{1/3} \end{eqnarray*}$$ for anyε> 0, whereis a primitive Dirichlet character withqprime and. This improves the previous known result.
