A simulation of the reaction pp→π⁰π⁰η→6γ with the PANDA detector — •Jean Franç Noël for the PANDA collaboration — Helmholtz-Institut für Strahlen- und Kernphysik, Universität Bonn, Nussallee 14-16, 53115 Bonn

An important frontier in high energy physics is the study of the formation of hadrons, which is described by quantum chromodynamics. The PANDA-experiment is an upcoming experiment, which will be located at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt. PANDA aims to shed new light on this topic by investigating deep inelastic scattering in antiproton-proton collisions, up to a center-of-mass energy of 5.5 GeV.

This talk will be focused on a simulation of the reconstruction of the decay pp→π⁰π⁰η, π⁰→γγ, η→γγ with the PANDA detector. Predictions for the underlying resonance structure are included into the simulation by usage of a so-called Partial Wave Analysis (PWA)-filter. These predictions are based on the Bonn-Gatchina PWA model.

In this presentation, I will show preliminary results for background simulations and the reconstruction of the corresponding Dalitz plot.

Supported within the programme ”Netzwerke 2021”, an initiative of the Ministry of Culture and Science of the State of Northrhine Westphalia (project ”NRW-FAIR”, ID: NW21-024-C)
