Check again the distance of approach. In order for the avatar to be realised, we have to perform a check in the CM system. We define a distance four-vector as

\[ (0, \Delta\vec{x}), \]

where $\Delta\vec{x}$ is the distance vector of the particles at their minimum distance of approach (i.e. at the avatar time). By boosting this four-vector to the CM frame of the two particles and we obtain a new four vector

\[ (\Delta t', \Delta\vec{x}'), \]

with a non-zero time component (the collision happens simultaneously for the two particles in the lab system, but not in the CM system). In order for the avatar to be realised, we require that

\[ |\Delta\vec{x}'| \leq \sqrt{\sigma/\pi}.\]

Note that $|\Delta\vec{x}'|\leq|\Delta\vec{x}|$; thus, the condition above is more restrictive than the check that we perform in G4INCL::Propagation::StandardPropagationModel::generateBinaryCollisionAvatar. In other words, the avatar generation cannot miss any physical collision avatars.
