Abstract
We obtain a new $\varOmega $-result for the remainder term $\psi (x)-x$ of a Beurling prime system for which the integers are very well-behaved in the sense that $N(x)=ax + \mathrm O(x^\beta )$ for some $a \gt 0$ and $\beta \lt 1/2$.
As part of this, we prove how bounds on $\psi (x)-x$ lead to zero-free regions for the Beurling zeta function, generalizing a result of Pintz to the Beurling setting. This may be of independent interest.
