Title: On the positronium g-factor.
Authors: Agil, J.1 (AUTHOR) jonathan.agil@lncmi.cnrs.fr, Battesti, R.2 (AUTHOR), Rizzo, C.2 (AUTHOR), Bakalov, D.3 (AUTHOR)

Subjects: Hyperfine coupling, Positronium
Abstract: In this letter, we recall the main facts concerning the g-factor of positronium and we show how the value of the g-factor of the positronium is important. Taking it better into consideration may provide a solution to the reported discrepancy between QED theory and experiments concerning the hyperfine splitting of the fundamental level of the positronium. We also give the only experimental value that existing experiments can provide, g Ps = 2.0023 ± 0.0012 at 3 σ . [ABSTRACT FROM AUTHOR]
