Left: Relative dynamical fluctuation $\sqrt{C_m}/M(\pt)_m$ for data and different event generators in pp collisions at $\sqrt{s}$= 7 TeV as a function of $\langle \rm{d}N_{\rm ch}/\rm d\eta \rangle$. Right: Ratio models to data. The red error band indicates the statistical and systematic data uncertainties added in quadrature. |
