I know this forum is for professional Mathematicians. I didn't know if the following question is fit or not fit for the site. If not, feel free to delete it.

>
>Here $c$ is a constant 

My questions are 

1. Is there a compact representation for this product?

2. What are some non-trivial  properties of this product?


3. Value of the regularized sum:

$$-\sum_{p}\ln\left( 1 - \frac{1}{(ep)^{1/2}} \right){\ln(p)}$$

Help me understand the analytic continuation of this function.


Or  consider

$$f(s) = \sum_{p}\left( 1 - \frac{1}{(ep)^{1/2}} \right)^{s\ln(p)}$$

$p$ belongs to set of primes


We can find f'(x)'s analytic continuation for some region containing s=0.


(This is the main motivation behind the question)

Edit:  Now by using the answer by R.Furman how can we calculate the product's value 'uniquely' at 1/2?






I think this is equal to zero under Riemann hypothesis. I need more insight into this. Any comments regarding this are welcome.
