# Systematics of $\bar{Q}q^4$ systems with a pure chromomagnetic interaction

Abstract : In the framework of a pure chromomagnetic Hamiltonian, we study all the states of Q̅q4 systems allowed by the Pauli principle. The wave functions are analyzed by group-theoretical techniques in a first step where the antiquark has an infinite mass and the quarks belong to an SU(3)F multiplet. The breaking of these symmetries is performed exactly through two parameters η and δ. The emphasis is put on the corresponding energies relative to the physical thresholds in Q̅q+q3. We propose a number of new multiquarks which could be stable under strong interactions.
