Title:    Transverse momentum transfer in QCD cascades

Authors:  E. A. De Wolf, P. Van Mechelen

Abstract: The evolution with rapidity of transverse momentum ($p_T$-)
          transfer is studied on parton level and on hadron level. It is
          shown that the fluctuations in $p_T$-transfer and the
          correlations between $p_T$-transfers at different points in
          rapidity exhibit sensitivity to the characteristics of the
          parton shower model in use.  A measure for the correlation
          length is introduced which may thus help to discriminate between
          DGLAP and BFKL-like parton evolution.
