Phys. Rev. Lett. 101, 232001 (2008) [4 pages]Is the Spectrum of Highly Excited Mesons Purely Coulombian?Received 8 July 2008; published 4 December 2008 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. © 2008 The American Physical Society URL:
