Is the spectrum of highly excited mesons purely coulombian?
We show that a static central potential may provide a precise description of highly excited light unflavored mesons. Because of string breaking, this potential becomes of chromoelectric type at sufficiently large quark-antiquark distances giving rise to a Coulombian spectrum. The same conclusion can be inferred for any other meson sector through a straightforward extension of our analysis.
