Detailed Description

A very simple sub-collision model, asuming static nucleons and just assuring that the individual nucleon-nucleon cross sections are preserved.

Constructor & Destructor Documentation

Pythia8::NaiveSubCollisionModel::NaiveSubCollisionModel ( )
inline

The default constructor simply lists the nucleon-nucleon cross sections.

multiset< SubCollision > Pythia8::NaiveSubCollisionModel::getCollisions ( vector< Nucleon > &  proj,
vector< Nucleon > &  targ,
const Vec4 &  bvec,
double &  T 
)
virtual

Take two vectors of Nucleons and an impact parameter vector and produce the corrsponding sub-collisions. Note that states of the nucleons may be changed.

Implements Pythia8::SubCollisionModel.
