What is w cut particle physics?

[amy2012]

As is shown in the website http://www-sldnt.slac.stanford.edu/snowmass/Software/EvtGen/documentation/pylist.txt is the pythia particle/parton data code, could someone tell me the meaning of parameters "col" "anti" and "w-cut".

Any comments are very welcome.

And where I could find those parameters?
Thanks!

Gluons have col=2, quarks have col=1, all other particles have col=0. Which quantum number do you expect?
"Anti" is for particles/antiparticles.

As w-cut is 10 times width, I think that is a restriction on the width (decay width?) to simplify calculations.

Have you looked at the Pythia manual?
