Hadamard Product for Riemann's Xi Function

[Charles49]

What is the infinite product for the function
$$\Xi(s)=\Gamma\left(\frac{s}{2}\right)\pi^{-s/2}\zeta(s)$$
?

You can manipulate the Hadamard's zeta function infinite product to get your answer.

 

[Avodyne]

$${\prod_n (1-s/s_n)\over s(s-1)}$$

where $s_n$ is a complex zero of $\zeta(s)$.
