CKIN(3)=PTLOW           ! Minimum Pt for hard 2->2 process.
CKIN(4)=PTHIGH             ! Maximum Pt for hard 2->2 process.
CKIN(9)=-4.2              ! Rapidity range for product with
CKIN(10)=4.2              ! largest rapidity in hard 2->2 process.
!
MSTP(81)=0     !TURN OFF MULTIPLE INTERACTIONS

MDCY(C111,1)=0    !SETS PI ZERO STABLE (LIMITS SIZE OF OUTPUT)
MDCY(15,1)=0 ! sets tau stable - this is important (for tauola)!
! The next line is _mandatory_ for RunII production
MSTJ(22)=2 !A particle is decayed only if its proper
!lifetime is smaller than PARJ(71)
! default should be ok. (strange particles stable, charm & bottom
! decay).




!MSTJ(22)=4        !A PARTICLE IS DECAYED ONLY IF THE DECAY
!VERTEX IS WITHIN A  CYLINDRICAL VOLUME
!WITH RADIUS PARJ(73) IN THE XY-PLANE AND
!EXTENT TO +-PARJ(74) IN THE Z DIRECTION.
!PARJ(73)=12.5     !IN MM
!PARJ(74)=1000.    !IN MM
