A Variant of the Truncated Perron's Formula and Primitive Roots

We show under the Generalised Riemann Hypothesis that for every $\delta >0$, almost every prime $q$ in $[Q,2Q]$ has the expected of prime primitive roots in the interval $[x,x+x^{\frac{1}{2}+\delta }]$ provided $Q$ is not more than $x^{\frac{2}{3}-ϵ}$. We obtain this via a variant of the classical truncated Perron’s formula for the partial sums of the coefficients of a Dirichlet series.
