Let L be a finite Galois extension of the number field K. We
unconditionally bound the least prime ideal of K occurring in the Chebotarev
Density Theorem as a power of the discriminant of L with an explicit
exponent. We also establish a quantitative Deuring-Heilbronn phenomenon for the
Dedekind zeta function.Comment: 23 pages; v3 corrects typos and improves Theorem 1.3 & Corollary 1.4;
