    1313Furthermore, their feedback on the actual densities is neglected. One can simulate in
    14 this fashion the effects of the almost constant target on the outgoing particles without modifying

    1616Thus the target automatically remains frozen and all products of the collisions of pions and
     
    1919Furthermore, since the ''perturbative'' particles do not react among themselves or modify the ''real''

    21 particles) during a run. Each piece is given a corresponding weight \(1/N_{test}\) and one simulates like
