Case2 result

d&Sigma- case2 correlation analysis results are presented here. Firstly, various spectyra are compared between "signal"(red) and "d on PA"(green) events.

"d from PA" events are having no structure, and considered to be BG. Hereafter, those events are eliminated from &Sigma- d case2 correlation analysis.

In the case, the reaction final state is completely occupied by,

K- + 4He -> &Sigma- + d + p

Dalitz plot of &Sigma- d p events

A Dalitz plot of a &Sigma- d p final state is shown below.
