VECBOS  Monte Carlo

Description:

VECBOS is a leading order Monte Carlo for inclusive production of a W-boson plus up to 4 jets or a Z-boson plus up to 3 jets in Hadron Colliders. The correlations of the vector boson decay fermions with the rest of the event are build in. Various parton density functions are available and distributions can be build in numerically.

The software:

The VECBOS program consists of five files vecbos.f , veclib.f , vecmat1.f , vecmat2.f and vecmat3.f .
Note: One needs the parton density function files .
