Abstract
We have developed a framework for the Monte Carlo simulation of experimental mass spectra in high-energy physics experiments. Contrary to existing simulation software, our framework has focused primarily on computational speed, rather than on extreme accuracy. A sufficient level of accuracy has been ensured, however, by including those elements that are identified to be the most essential for determining the shapes of these mass spectra, and by excluding all elements of which the effects are deemed only marginal. Specifically, the resulting simulation model includes decay kinematics and the most important detection effects: acceptance, resolution and bremsstrahlung effects. Moreover, it can generate background shapes for peaking or semi-peaking backgrounds by simulating the effects of particle misidentifications or of the partial reconstruction of events. In addition, a method for calibrating the free parameters in the simulation model to experimental datasets, based on simulated annealing, is presented. This calibration procedure allows the model to be adapted to any general high-energy collider experiment. Finally, we also discuss an application of the model, where the simulation framework is used for fitting background-dominated experimental mass spectra.
