Doubly Charmed Mesons

Abstract

Doubly charmed mesons are studied within a quark model framework. We solve the four-quark Schord̈inger equation by means of a variational approach by using different interacting potentials. Our results point to the existence of a stable isoscalar doubly charmed four-quark meson with quantum numbers $J^P=1^{+}$.
