Hi everyone,
is there one of you who worked already with the PARTWAVE model of EvtGen?
I want to use it for the decay of Xi(1820)->Lambda0 + K- with l=2
For this I extended the evt.pdl file with the line:
add p Particle Xi(1820)- 23314 1.8230000e+00 2.4000000e-02 5.0000000e-03 -3 3 0.0000000e+00 0
As decay file I use the attached Dec-file. I set the decay model to PARTWAVE 0.0 0.0 0.0 0.0 1.0 0.0 like described in the documentation.
But if I run the simulation macro the following message appears and the macro stops.
EvtGen:Mixing type integer set to 1
EvtGen:Done initializing EvtGen
EvtGen:In readDecayFile, reading:/private/puetz/mysimulations/analysis/XiMinus_1820_lambda0_K.dec
EvtGen:As requested, PHOTOS will be turned off.
EvtGen:PARTWAVE generator expected
EvtGen:4
EvtGen: arguments but found:6
Xi(1820)- -> Lambda0 K- (PARTWAVE)
EvtGen:Will terminate execution!
With the example file trunk/pgenerators/EvtGen/EvtGen/R01-03-00/test/exampleFiles/PARTWAVE.DEC the simulation macro is working fine.
If I reduce the number of arguments to PARTWAVE 0.0 0.0 1.0 0.0 the simulation is running without any error. I am not sure if it is correct to use it this way.
Can someone help me?
