Four-loop correction to σtot(e^+e^-\rightarrow hadrons) in QCD and the problem of determining the parameter ΛvecMS
Calculations of the four-loop correction of order О (a]) to atot (e + e~ hadrons) in QCD are reported. There is a discussion of how the large correction found influences the procedure for determining the value of the parameter Л ш from data from e + e ~ colliders in various energy ranges.
