The average event shape variables is studied in electron positron annihilation within the context of next to leading order(NLO) perturbative QCD prediction. We measure the strong coupling constant by fitting the NLO model ...

We measure the strong coupling constant at NNLO corrections. We do this analysis with moments of event shape variables: thrust, C parameter, heavy jet mass, wide and total jet broadening, by fitting the L3 and DELPHI data ...

We present the properties of the C parameter as an event shape variable. We calculate the coupling constants in the perturbative and also in the non perturbative part of the QCD theory, using the dispersive as well as the ...

The fluorescence, absorption spectra and Z-scan (open aperture) were studied in mixture of anionic dye (Fluorescein Sodium Salt-FSS) and cationic dye (Rhodamine B-RhB) with low size of water droplets. The droplet was ...

In this paper, the resonant frequencies of a dual mode square SIW cavity with a corner cut perturbation are calculated, analytically. Since introducing the perturbation makes small changes in the field pattern of this cavity, the perturbation theory...

A new non-equilibrium statistical thermodynamics perturbation theory was developed which could be applied in parallel to equilibrium statistical thermodynamics perturbation theory. The present method is based on the reminiscent of Boltzmann H...

Abstract. The problem of small amplitude electron-acoustic solitary waves (EASWs) is discussed using the reductive perturbation theory in magnetized plasmas consisting of cold electrons, hot electrons obeying nonextensive distribution and stationary...
