Analytical continuation of Euler prime product for $\mathrm{\Re }(s)>\frac{1}{2}$ assuming (RH)

We analytically continue the Euler prime product for $\mathrm{\Re }(s)>\frac{1}{2}$ (except for its pole $s=1$) assuming (RH) by introducing a new factor to the Euler product. We also discuss how to recover the Mertens’s 3rd Theorem at $s=1$ case, and how to apply the same technique to analytically continue other similar Euler products. In the last part, we also construct a simple script in Pari/GP to compute the Euler product and verify the calculations numerically.
