2023 KLF Simulations

Installing Software

The reconstruction and analysis software are built on the same software stack used for the analysis of photon beam measurements with the GlueX detector.

• You can find some general information on GlueX software and computing at this page.
• A general overview of the GlueX software can be found here.

There are a couple of different ways to install the GlueX software stack.

• You can follow these instructions to build the full software stack locally.
• Or you can run the GlueX software in a container.

Note that the GlueX software installation has been verified to work on RedHat/CentOS 7 and various Ubuntu versions - basically anywhere you can install the scons package. Instructions exist on how to install on RedHat/CentOS 8, link to them. The software currently does not build under RedHat/CentOS 9 - you are better off running the software inside a container in this case, for now.

A version of the dedicated KLF event generator can be downloaded and installed from here https://github.com/sdobbs/KLGenerator_hddm_V3 using the following commands:

git clone https://github.com/sdobbs/KLGenerator_hddm_V3
cd KLGenerator_hddm_V3
scons install

Note that KLGenerator_hddm_V3 is installed under $HALLD_MY/bin, so make sure that you have that directory in your PATH.

Generating Events

The KLGenerator_hddm_V3 program has some good online help through the -h switch.

For an example, let's try generating 1M KL p -> Ks p events.
