In this work, we address the question, "how large is the least prime p of the form p = x 2 + Dy2 relative to D?" More generally, we study the least prime represented by a positive-definite binary quadratic form of prime discriminant D, and we prove a Linnik-type theorem: the least such prime is bounded by a constant times DL for some large but explicit constant L > 0. While such a result has been established before, our methods are significantly different and based on sieve theoretic machinery. In particular, other proofs of this result require deeper input from the zeros of class group L-functions, namely a log-free zero-density estimate and a quantitative form of the Deuring-Heilbronn phenomenon. By comparison, the only input we require from the zeros of these L-functions is a zero-free region of classical type. Along the way, we establish a couple of results that may be of independent interest: (1) a large sieve-type inequality for class group characters over almost-primes, and (2) an approximation result for values of L-functions by partial Euler products whose length is comparable (in the log scale) to the conductor of the L-function.
