Could anyone please explain what resonance in particle physics is and what resonance peaks are? Also how resonance relates to certain results? the certain results are the decay of a particle which leads to a positron energy, electron energy and an angle. the data i found was the reconstructed mass. how would i find the resonance peak of the reconstructed mass?
A resonance (in particle physics) is the peak located around a certain energy found in functions that quantify the given rate at which scattered particles can be detected at a given angle (in scattering experiments). The peaks are associated with subatomic particles and their excitations (i.e., any quantum state of these particles that is higher than ground state).
