20 | 20 | * Program `ElegentTDistributionSampler` to build a number of '''t-distributions''' of interest (t being four-momentum transfer squared), e.g. differential and cumulative cross-sections. The distributions are generated at a given collision energy and are saved as a ROOT file. For details please refer to the [[TDistributionFileDescription|t-distribution file description]]). |
21 | 21 | * Program `ElegentBDistributionSampler` to build a number of '''b-distributions''' of interest (b stands for impact parameter). At the moment, only profile functions are generated and saved as a ROOT file. |
| 22 | * Program `ElegentSDistributionSampler` to build a number of '''s-distributions''' of interest (s stands for the square of interaction energy). |
22 | 23 | * Class `Generator` that loads a specified cumulative distribution function from a t-distribution ROOT file and generates random events in the [[http://lcgapp.cern.ch/project/simu/HepMC|HepMC format]]. This class can easily be embedded in any program. As an example, you can have a look at the [[source:/trunk/src/ElegentTest.cc|ElegentTest program]]. |
