# long process

Asked by
NADY

Hi Olivir , Hi Johan

I have a probem

I know that Pythia8 can process 2 -> 3 Maximum

but I have a process in my implemented model 2 -->7 that is :

define p = u u~ g

generate p p > z , (z > Zp N1 N1 /ve , (N1 > w+ e- /ve , w+ > e+ ve ) , (N1 > z ve , z > mu- mu+))

where N1 is heavy neutrino Zp is Z prime

to solve this problem i divided this long process by :

generate p p > z @1

add process z > Zp N1 N1 /ve @2

add process N1 > w+ e- /ve @3

add process w+ > e+ ve @4

add process N1 > z ve @5

add process z > mu- mu+ @6

To export matrix elements code to Pythia8

THIS IS TRUE OR FALSE

Please help me

Cheers,

Nady
