In this writeup, we will present an example that will use Pythia8 event generator, as it has been most heavily used in production so far. In CMSSW we have interfaces to many physics event generators that are of interest to the collaboration. sets of outgoing particles produced in the interactions between two incoming particles, must be the first step in the Monte Carlo event processing chain. Generation of high-energy-physics events, i.e. We will provide specific comments and suggestions when applicable. Where necessary, we'll provide specific tips, especially for the most recent releases.Īt the same time, we would like to mention that newer developments have happened in more recently released, and imposed modifications of certain details. In general, a user should assume CMSSW_10_2_X and higher release cycle. In this section, we will present several How-To's on the most often used features and utilities, will show several examples, and will provide links to more detailed documents. However, if you can not find the event sample you would like to use (or compatible with the CMSSW version that you are using), you may want to produce your own Monte Carlo samples ("private samples"). Physics event generation and detector simulation are the earliest steps in the event processing chain that leads to producing Monte Carlo samples suitable for physics analysis.Īn ample variety of the Monte Carlo samples for various types of physics analysis are produced and distributed centrally. Walk-through Example Fast Simulation Configuration File.Walk-through Example Full Simulation Configuration File.Composing Fast Simulation Configuration Application. Composing Full Simulation Configuration Application.It should serve as a jump-start for people who will need to prepare configuration applications for central production of the Monte Carlo samples, as representatives of their Physics groups.Īnother group of people we aim onto are those who will need to produce their Monte Carlo samples on a private basis, i.e. This page provides an entry point to the physics event generation and detector simulation in CMSSW. 6.1 Thirty-Minute Introduction to Generation and Simulation
