[Clas12_verystrange] simulation

[Derek Glazier]

Hi,
   The problem acceptance arises from detecting negative particles 
decaying from the Omega. Just measuring K+K+K0 isn't so much of an 
acceptance problem, but instead you have a background problem (estimated 
1:10 signal to background from Pythia). Detecting the K- for example 
greatly decreased the background at the expense of acceptance. 
Increasing the field greatly decreases the K- acceptance. High field is 
probably good for +ve charged kaons.

Cheers
Derek
