Kinematic Selection Criteria in the Search for Resonances

Figure 1

Phase space 𝑚-bands of the particles 𝐚 and 𝐛 in 𝑅→𝐚+𝐛 decays as a function of the resonance momentum 𝑃_𝑅. The dashed line on (c) corresponds to the momentum cut 𝑝_𝜋=0.15 GeV (see Section 3). The dashed line on (d) corresponds to (2.12).
