Flavor symmetries and final-state interactions in hadronic decays (A01)

• Subject Area: Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
• Term: from 2012 to 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 196253076

An accurate control over final-state interactions (FSIs) is of paramount importance for our understanding of the most diverse aspects of particle decays involving hadrons: On the one hand, FSIs need to be considered in order to understand various aspects of the fundamental decay mechanism of a heavy state; on the other hand, they may teach us about the dynamics of the lighter decay products. Both aspects are central to this project, which focuses on the interplay between heavy-hadron decays and light-hadron dynamics, including both hidden and open charm and bottom mesons, with an emphasis on the large data body from BESIII, LHCb and COMPASS.
