In this paper, we consider a nonlinear Schrödinger system with quadratic interaction. We extend the recent results of Fukaya et al. (Math. Ann. 2024) and show that the system has a ground state in (Formula presented.) when the mass parameter (Formula presented.) is larger than (Formula presented.).
