“…1. As opposed to event-shapes, such as the y 23 -distribution [21,22], jet rates do not obey simple exponentiation (except for the two-jet rate). For an observable that does not exponentiate, the viable matching scheme is the so-called R-matching [23].…”

We present a measurement of the strong coupling α S using the three-jet rate measured with the Durham algorithm in e + e − -annihilation using data of the JADE experiment at centre-of-mass energies between 14 and 44 GeV. Recent theoretical improvements provide predictions of the three-jet rate in e + e − -annihilation at next-to-next-to-leading order. In this paper a measurement of the three-jet rate is used to determine the strong coupling α S from a comparison to next-to-next-to-leading order predictions matched with next-to-leading logarithmic approximations and yields a value for the strong coupling± 0.0054(had) ± 0.0007(theo), consistent with the world average.

“…Event shape observables used for this analysis are thrust (1 − T ) [21,22], heavy jet mass (M H ) [23], wide and total jet broadening (B W and B T ) [24], C-Parameter (C) [25][26][27] and the transition value between 2 and 3 jet configurations [28,29] The event shape observables are calculated from selected charged particle tracks and calorimeter clusters after correcting for double counting of energy as described in [15]. We compared the data with the predictions from Monte Carlo simulations as described above and found good agreement at all energy points.…”

Event Shape Data from e + e − annihilation into hadrons collected by the JADE experiment at centre-of-mass energies between 14 GeV and 44 GeV are used to determine the strong coupling α S . QCD predictions complete to next-to-next-to-leading order (NNLO), alternatively combined with resummed next-to-leading-log-approximation (NNLO + NLLA) calculations, are used. The combined value from six different event shape observables at the six JADE centre-of-mass energies using the NNLO calculations is The stability of the NNLO and NNLO + NLLA results with respect to missing higher order contributions, studied by variations of the renormalisation scale, is improved compared to previous results obtained with NLO + NLLA or with NLO predictions only. The observed energy dependence of α S agrees with the QCD prediction of asymptotic freedom and excludes absence of running with 99% confidence level.

Abstract:We present in detail a calculation of the next-to-leading order QCD corrections to the process e + e − → 3 jets with massive quarks. To isolate the soft and collinear divergencies of the four parton matrix elements, we modify the phase space slicing method to account for masses. Our computation allows for the prediction of oriented three jet events involving heavy quarks, both on and off the Z resonance, and of any event shape variable which is dominated by three jet configurations. We show next-to-leading order results for the three jet fraction, the differential two jet rate, and for the thrust distribution at various c.m. energies.
