Plots in Phys. Rev. Lett. 84, 5279 (2000)

"Search for the Decay K_L -> pi⁰ mu⁺mu^-"

• m_vs_pt.eps
  Reconstructed P_T² vs m after all other selection criteria, for the data. The box indicates the signal region; events in the lower left are predominantly K_L->pi⁺pi^-pi⁰ with pi^+- decays in flight.
  
  -------------------------------------------------------
• m.eps
  Reconstructed m after all other selection criteria, for the data (dots), and the total background estimate (line). The arrows indicate the range of values of m accepted. The small bump in the background at the K_L mass is from K_L->mu⁺mu^-gamma gamma.
