Abstract: We show that a static central potential may provide a precise description ofhighly excited light unflavoured mesons. Due to string breaking this potentialbecomes of chromoelectric type at sufficiently large quark-antiquark distancesgiving rise to a coulombian spectrum. The same conclusion can be inferred forany other meson sector through a straightforward extension of our analysis.
