Combined QCD analysis of e + e − data at √ s = 14 to 172 GeV

چکیده
A study of the energy dependence of event shape observables is presented. The strong coupling constant αs has been determined from the mean values of six event shape observables. Power corrections, employed for the measurement of αs, have been found to approximately account for hadronisation effects.

In this paper, we investigate the multiplicity of charged particles in e+ e– annihilation by using different models. To achieve this we first fit the multiplicity distribution of charged particles in the energy range of 54-57 GeV by using both the Poisson distribution and KNO scaling, then we compare these results with multiplicity distribution at the lower energies. This comparison shows that...
متن کاملبررسی مدلهای گوناگون QCD و مقایسه آنها با نتایج حاصل از نابودی e+e- در انرژی مرکز جرم60GeV
We present the QCD models based on the hadronization of final states of e+e- annihilations, in 60 GeV centre of mass energy in the AMY detector at the KEK collider TRISTAN. To achieve this, we first find the jet axis by using the momentum tensor and diagonilizing it for each event. The models under consideration are the Webber, the Matrix Elements and the Parton Shower. In most cases our resu...
متن کاملMULTIHADRON PRODUCTION FOR e e FOR FROM 50 TO 61 GeV, C. M. ENERGIES AND COMPARISON WITH MULTIHADRON PRODUCTION IN HADRONIC INTERACTIONS
Average values of< 1- T >where T is the thrust are presented for e: e: AMY data and are compared with their values in hadronic interactions. As far as possible, similar analysis techniques have been employed in the two different interactions. Similar variation with E is observed for this average in both data. The values of < PT> and < PL > relative to the thrust axis in e e are simila...
متن کاملDetermination of Λ ( 5 ) MS from the measured energy dependence of < 1 − Thrust
We directly fit the experimentally measured energy dependence of the average value of 1−Thrust, <1−T>, over the e+e− centre-of-mass energy range Q = 14− 172 GeV to the QCD expectation obtained by integrating up the evolution equation for d<1−T>/d logQ in terms of <1−T>. We fit for Λ (5) MS , uncalculated O(αS) and higher perturbative corrections parameterized by the scheme invariant ρ2, and the...
متن کاملC-Parameter and Jet Broadening at PETRA Energies
e+e− annihilation data recorded by the JADE detector at PETRA were used to measure the C-parameter for the first time at √ s = 35 and 44 GeV. The distributions were compared to a resummed QCD calculation. In addition, we applied extended resummed calculations to the total and wide jet broadening variables, BT and BW . We combined the results on αs with those of our previous study of differentia...
