Detailed Description

The HVStringPT class is used to select select HV transverse momenta.

Member Function Documentation

void init ( )
virtual

Initialize data members.

The HVStringPT class is used to select pT in HV fragmentation.

Initialize data members of the string pT selection.

Parameter of the pT width. No enhancement, since this is finetuning.

Parameter for pT suppression in MiniStringFragmentation.

Reimplemented from StringPT.
