Abstract: (APS)
Order-αs2 corrections to the annihilation of e+e− into hadrons are computed analytically. We briefly discuss the technique, which involves the extension to noninteger dimensions of Chebyshev expansions. In the energy range 15-30 GeV (five flavors) we find R=3ΣeQ2{1+αs(q)π−0.94[αs(q)π]2+…}, where αs is the momentum-space subtracted strong-coupling constant. Our result agrees with that of Dine and Sapirstein, and Chetyrkin, Kataev, and Tkachov.- ELECTRON POSITRON: ANNIHILATION
