TennGen200

Adaptation of TennGen for 200 GeV Au-Au collisions. Random number generation of heavy ion collisions based off sampling measured charged particle momentum spectra, particle flow coefficents and charged particle multiplicty at RHIC. Implements Van-Neuman method of accept/rejection to speed up event generation.

Current Features:

• |#eta| < 1.1.
• Harmonic coefficents: #v_1, #v_2, #v_3, #v_4.
• All charged particles: #pi^{#pm}, #k^{#pm}, p and #bar{p}.
• Variable particle multiplicities.
• Centrality binning: 0-10%, 10-20%, 20-40%, 40-60%.

Quick start:

1. Change to your local root install directory in file.
2. <chmod +x tenngen-config>
3. <./tenngen-config>

This will make the tenngen library and create an AuAu200Data.root file in your </examples/data> directory. This root file is nessicary to run any TennGen200 event generation. If you delete this file, it can be regenerated by an exicutable <./examples/data/AuAuData>.

Examples of using TennGen can be found in .

Datafiles and fitted distributions can be located in </share/data>. There is also png files of the current fits of momentum distributions and multiplicty distribution in <./share/distros-PNG>.
