Special attributes for a Kink Vertex

This routine allows to get special attributes defined only for Kink vertices produced by JULIA version 302 and after. These quantities are available from POTs, DSTs and MINIs.

Input arguments:

IVX

ALPHA vertex number of a kink vertex (IVX must be between KFKIV and KLKIV, see sec 7.1.2).

Output arguments:

IER

= 0 if IVX is really a kink vertex, = 1 if not.

PKINK

Momentum of parent track at the kink position

PTOUT

Pt of outgoing charged particle relative to parent

PLOUT

Pl of outgoing charged particle relative to parent

IHYPK

Hypothesis of mass cuts satisfied by this decay:

• = 1 $\pi$ $\rightarrow$ $\mu$$\nu$
• = 2 K $\rightarrow$ $\mu$$\nu$
• = 3 K $\rightarrow$ $\pi$$\pi^{0}_{}$
• = 4 $\Sigma^{+}_{}$ $\rightarrow$ p$\pi^{0}_{}$
• = 5 $\Sigma^{+}_{}$ $\rightarrow$ n$\pi^{+}_{}$
• = 6 $\Sigma^{-}_{}$ $\rightarrow$ n$\pi^{-}_{}$
• = 7 $\Xi^{-}_{}$ $\rightarrow$ $\Lambda$$\pi^{-}_{}$
• = 8 $\Omega^{-}_{}$ $\rightarrow$ $\Lambda$K^-
• = 9 $\Omega^{-}_{}$ $\rightarrow$ $\Xi^{0}_{}$$\pi^{-}_{}$
• = 10 $\Omega^{-}_{}$ $\rightarrow$ $\Xi^{-}_{}$$\pi^{0}_{}$
• = 0 if none of the above hypotheses are satisfied

This routine allows to get the number and list of charged tracks ending in Kink vertices produced by JULIA version 302 and after.

Output arguments:

NKINKS

= number of kink vertices in the event.

LISTKINKS(I)

= list of charged tracks ending in the I=1,NKINKS kink vertices; must be dimensioned to 50 in the calling routine.
