Estimates of the O($\alpha_{s}^{4}$) corrections to $\sigma_{tot}$(e+e- --> hadrons), $\Gamma$($\tau$ --> $\nu_{\tau}$ + hadrons) and deep inelastic scattering sum rules
We present the estimates of the order O(\alpha_s^4) QCD corrections to R(s)=\sigma_{tot}(e^+e^-\rightarrow hadrons)/ \sigma (e^+e^\rightarrow \mu^+\mu^-), R_{\tau}= \Gamma(\tau \rigtarrow \nu_{\tau}+hadrons)/\Gamma(\tau\rightarrow \nu_{tau}\overline{\nu}_ {e}e) and to the deep inelastic scattering s...

description | We present the estimates of the order O(\alpha_s^4) QCD corrections to R(s)=\sigma_{tot}(e^+e^-\rightarrow hadrons)/ \sigma (e^+e^\rightarrow \mu^+\mu^-), R_{\tau}= \Gamma(\tau \rigtarrow \nu_{\tau}+hadrons)/\Gamma(\tau\rightarrow \nu_{tau}\overline{\nu}_ {e}e) and to the deep inelastic scattering sum rules, namely to the non-polarized and polarized Bjorken sum rules and to the Gross-Llewellyn Smith sum rule. The estimates are obtained in the \overline{MS}- scheme using the principle of minimal sensitivety and the effective charges approach. |
