Abstract
Let p be a prime number and \(f\in {S_{n}^{l}}({\Gamma }_{0}(N), \psi )\) be a Siegel cusp eigenform of genus n. We consider the standard zeta function D (Np)(f,s,χ), which takes algebraic values at critical points after normalization. We construct two h-admissible measures μ + and μ − for certain h = [4ord p (α 0(p))] + 1 explained in the Main Theorem with the following properties:
-
(i)
For all pairs (s,χ) such that \(\chi \in X_{p}^{\text {tors}}\) is a non-trivial Dirichlet characters, \(s\in \mathbb {Z}\) with 1 ≤ s ≤ l − n, s ≡ δ mod 2 and for s = 1 the character χ 2 is non-trivial, the following equality holds
$${\int}_{\mathbb{Z}_{p}^{\times}}\chi x_{p}^{-s}d\mu^{+}=i_{p}\left( c_{\chi}^{s(n+1)}A^{+}(\chi)\cdot E_{p}^{+}(s, \chi\chi^{0})\frac{{\Lambda}_{\infty}^{+}(s)}{\langle f_{0}, f_{0}\rangle}\cdot D^{(Np)}(f, s, \overline{\chi\chi^{0}})\right), $$where f 0 is a modular form, associated to f and an embedding \(i_{p}:\overline {\mathbb {Q}}\hookrightarrow \mathbb {C}_{p}\) is fixed.

(ii)
For all pairs (s,χ) such that \(\chi \in X_{p}^{\text {tors}}\) is a non-trivial Dirichlet character, \(s\in \mathbb {Z}\) with 1 − l + n ≤ s ≤ 0, s ≡ δ + 1 mod 2 the following equality holds
$$\begin{array}{@{}rcl@{}} {\int}_{\mathbb{Z}_{p}^{\times}}\chi x_{p}^{s-1}d\mu^{-}&=&i_{p}\bigg(c_{\chi}^{n(1-s)}A^{+}(\chi)\cdot E_{p}^{-}(1-s, \chi\chi^{0})\frac{{\Lambda}_{\infty}^{-}(s)}{\langle f_{0}, f_{0}\rangle}\\ &&\times D^{(Np)}(f, 1-s, \overline{\chi\chi^{0}})\bigg). \end{array} $$
Here, δ = 0 or 1 according to whether χ(−1) = 1 or χ(−1) = −1 and Λ ∞ (s), A(χ), E p (s,ψ) are certain elementary factors including Gauss sum, Satake p-parameters, conductor c χ of Dirichlet character χ etc.
