Strong coupling constant at NNLO from DIS data
Abstract
We discuss the results of our recent analysis [1] of deep inelastic scattering data on F2 structure function in the non-singlet approximation with next-to-next-to-leading-order accuracy. The study of high statistics deep inelastic scattering data provided by BCDMS, SLAC, NMC and BFP collaborations was performed with a special emphasis placed on the higher twist contributions. For the coupling constant the following value alfas(MZ2) = 0.1167 +- 0.0022 (total exp. error) was found.
