description: Mean value of the event shape variable C-PARAM.
description: DESY-HERA. Measurement of event shape distributions and their mean values in neutral current DIS of 27.5 GeV electrons and positrons with 920 GeV protons. The data cover the kinematic range in Q**2 of 80 to 20480 GeV**2, in X from 0.0024 to 0.6 and Y from 0.04 to 0.9. The data, which has an integrated luminosity of 82.2 pb-1 extends with increased statistics the previous ZEUS measurement reported in EPJ C27,531(2003). The event shape variables are the following.. THRUST(C=T) =& gt; Thrust w.r.t. the thrust axis.. THRUST(C=G) =& gt; Thrust w.r.t. the virtual photon axis.. B(C=T) =& gt; Jet Broadening w.r.t. the thrust axis.. B(C=G) =& gt; Jet Broadening w.r.t. the virtual photon axis.. RHO =& gt; Invariant Jet Mass.. C-PARAM =& gt; C-Parameter.. Y2 =& gt; the borderline YCUT in the jet finding between (1+1) and (1+2) jets.. KOUT =& gt; the momentum out of the event plane.. Numerical values supplied by A. Savin.. This part contains the Mean Values.
