Abstract: This paper is concerned with the Schr\"odinger-Poisson-Slater (SPS) equations incorporating both Coulomb-Sobolev and Sobolev critical exponents in $\mathbb{R}^3$. These double critical exponents, specifically 3 and 6, lead to the non-compactness of embeddings in the relevant function space. By utilizing the Pohozaev identity and the Br\'{e}zis-Lieb lemma, we show the existence of ground state solutions.

Key words: Schr?dinger-Poisson-Slater equation, Pohozaev identity, Coulomb-Sobolev inequality
