Description
I present the longitudinal and transverse momentum distributions, two particle eta-phi correlations and azimuthal anisotropy (v2) of pions in jets of high mass, obtained in a newly developed fragmentation model [1-4]. In this model, the jet mass is used as the fragmentation scale, and the scale evolution is calculated in the phi^3 theory. The initial form of the fragmentation function at starting scale Q0 is obtained in a model based on a micro-canonical statistics and superimposed negative-binomial multiplicity fluctuations.
