  In this paper, we study the Schr\"odinger equation associated with the
Weinstein operators and we prove the existence and uniqueness of global
solutions to Schr\"odinger-Weinstein equations in\\ $C\left(\left(-T_{\min },
T_{\max }\right) ; L_{\alpha}^{2}\left(\mathbb{R}^{d+1}_+\right)\right) \bigcap
L_{l o c}^{q_{1}}\left(\left(-T_{\min }, T_{\max }\right) ;
L_{\alpha}^{r_{1}}\left(\mathbb{R}^{d+1}_+\right)\right)$ \\ on initial
condition in $L_{\alpha}^{2}\left(\mathbb{R}^{d+1}_+\right)$
