Abstract: We present data on energy-energy correlations (EEC) and their related asymmetry (AEEC) ine$^+$e$^−$ annihilation in the centre of mass energy range 12$<$W$≦$46.8 GeV. The energy and angular dependence of the EEC in the central region is well described by Oα${_s^2}$ QCD plus a fragmentation term proportional to 1/$\sqrt{s}$. BareO(α)${_s^2}$ QCD reproduces our data for the large angle region of the AEEC. Nonperturbative effects for the latter are estimated with the help of fragmentation models. From various analyses using different approximations, we find that values for Λ$\dfrac{}{_{MS}}$ in the range 0.1–0.3 GeV give a good description of the data. We also compare analytical calculations in QCD for the EEC in the back-to-back region to our data. The theoretical predictions describe well both the angular and energy dependence of the data in the back-to-back region.
