Pauli principle forbids QQQQQQQQQ bound states
Abstract
Lattice QCD studies have shown the attractive character of the 1S0 QQQQQQ, Q=s,c,b, interaction, predicting deeply bound states as the mass of the heavy quark increases. This has led to the question of the possible existence of bound states of more than two QQQ baryons, in particular QQQQQQQQQ bound states. We discuss how these states might not exist in nature in any flavor sector. The reason would be due to the simultaneous action of two consequences of the Pauli principle in the different partial waves: one at the baryon level, affecting the 1S0 partial wave, and the other due to the quark substructure, affecting the 5S2 partial wave.
