Hadron Molecules Revisted

Abstract

Hadron Molecules are particles made out of hadrons that are held together by self interactions. In this report we discuss seven such molecules and their self interactions. The $f_0(980)$, $a_0(980)$, $f_1(1400)$, $\Delta N(2150)$ and ${\pi }_1(1400)$ molecular structure is given. We predict that two more states the $K\overline{K}K(1500)$ and $a_1(1400)$ should be found.
