4 | For kinky string decay simulation we have assumed the two steps process: |
---|
5 | \begin{enumerate} |
---|
6 | \item split gluon $g\rightarrow q_1 \bar{q}_1$ and create two longitudinal |
---|
7 | strings; |
---|
8 | \item decay longitudunal strings $q\bar{q}_1 \rightarrow h$ and |
---|
9 | $\bar{q}q_1 \rightarrow h$ into hadrons $h$. |
---|
10 | \end{enumerate} |
---|
11 | The production of $q_1\bar{q}_1$ is considered similar (the same sampling of |
---|
12 | quark flavors and the same $p_t$-distribution for the quarks) as a production |
---|
13 | of $q\bar{q}$-pairs during a longitudinal string decay. |
---|
14 | We use the $g\rightarrow q_1\bar{q}_1$ splitting function \cite{APKW80}: |
---|
15 | \begin{equation} |
---|
16 | \label{KSD1}f^{q}_{g}(z)=z^2+(1-z)^2, |
---|
17 | \end{equation} |
---|
18 | where $z=\frac{E_q+p^z_q}{E_g+p^z_g}$, derived by Altarelli and |
---|
19 | Parisi \cite{AP77}. |
