  "abstract": "In this paper, we provide new explicit examples of semitoric systems. More precisely, for any natural number $n$, we give a semtioric moment map $F_n$ with $2n$ focus-focus singularities defined on a symplectic manifold $(M_n,ω_n)$ of diffeomorphism type $\\mathbb{CP}^2\\sharp(2n+1)\\overline{\\mathbb{CP}}{}^2$.",
