## Abstract

In a previous paper of the authors, we showed that for any polynomials P_{1}…P_{k} ε Z[m] with P_{1}(0) = … = P_{k}(0) and any subset A of the primes in [N] = {1, …, N} of relative density at least φ > 0, one can find a "polynomial progression" a+P_{1}(r), …, a+P_{k}(r) in A with 0 <|r|≤N^{o(1)}, if N is sufficiently large depending on k, P_{1}, …, P_{k} and φ. In this paper we shorten the size of this progression to 0 <|r|≤log^{L}N, where L depends on k, P_{1}, …, P_{k} and φ. In the linear case P_{i} =(i-1)m, we can take L independent of φ. The main new ingredient is the use of the densification method of Conlon, Fox, and Zhao to avoid having to directly correlate the enveloping sieve with dual functions of unbounded functions.
