Description:
Author(s): Diogo Boito, Maarten Golterman, Alexander Keshavarzi, Kim Maltman, Daisuke Nomura, Santiago Peris, and Thomas Teubner We use a new compilation of the hadronic R -ratio from available data for the process e + e − → hadrons to determine the strong coupling, α s . We make use of all data for the R -ratio from threshold to a center-of-mass energy of 2 GeV by employing finite-energy sum rules. Data above 2 GeV, for which at pres... [Phys. Rev.
