Qcut and xqcut are the two main parameters related to the matching procedure:

   * xqcut defines the minimal distance between partons at the matrix-element level 
   * Qcut is the matching scale: maximal distance between a parton and a jet to be matched with each other.

Both parameters use  $K_{T}$ measure as distance definition.
