| contents | We present a state-of-the-art analysis on determining the strong coupling constant $α_s(m_Z)$ from available $e^+e^-$ data for the Heavy Jet Mass (HJM) distribution. Dijet resummation is supplemented with additional resummation of shoulder logarithms appearing around the symmetric 3-jet configuration of the HJM spectrum. In addition to $α_s(m_Z)$ we further obtain numerical results for two non-perturbative parameters, $Ω_1^ρ$ and $Θ_1$, encompassing effects from dijet and trijet hadronization effects, respectively. |
