Abstract

In a previous paper we proved that if an L-function F from the Selberg class has degree 2, its conductor q_F is a prime number and F is weakly twist-regular at all primes p≠ q_F, then F has a polynomial Euler product. In this paper we extend this result to L-functions of degree 2 with square-free conductor q_F, which are weakly twist-regular at all primes p\nmid q_F
