Tuning the Geant4 FTF Model Using Experimental Data of the NA61/SHINE Collaboration
The FTF model is an implementation of the well-known FRITIOF model of Lund University. It is used in the Geant4 package for simulations of hadron–nucleon, hadron–nucleus and nucleus–nucleus interactions at high energies. Thus, for various practical applications, it is important to have correct simulation results. This aim can be reached in a fine tuning of model parameters. In the presented paper, probabilities of strange meson production in quark and diquark fragmentations, and a probability of meson emission by diquarks are determined. A good description of the NA61/SHINE data on production of \({{\pi }^{ \pm }}\) mesons in \(pp\), \(p{\text{C}}\) and \(AA\) interactions has been achieved. However, there remains the problem of describing yields of strange mesons in nucleus–nucleus collisions. The model significantly underestimates yields of \({{K}^{ + }}\) and \({{K}^{ - }}\) mesons in \(^{{40}}{\text{Ar}} + \,{{\,}^{{45}}}{\text{Sc}}\) interactions.
期刊介绍:
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
