A GEANT4-based simulation is developed for the endcap time of flight (ETOF) upgrade based on multi-gap resistive plate chambers (MRPC) for the BESIII experiment. The MRPC prototype and the simulation method are described. Using a full Monte-Carlo simulation, the influence of high voltage and threshold on time resolution and detection efficiency are investigated. The preliminary results from simulation are presented and are compared with the experimental data taken with the prototype MRPC modules.

“…Each end cap station has 36 trapezoidally shaped MRPC modules arranged in a circular double layers [20] and adjacent modules are staggered slightly to avoid dead regions. The inner and outer radii of the effective areas of the MRPC rings are 501 and 822 mm, respectively.…”

Purpose The end cap time of flight at Beijing Spectrometer is upgraded with multi-gap resistive plate chamber technology in order to improve the charged particle identification capability. The time-over-threshold is used for the time slewing correction instead of the signal amplitude. Methods The correlation of the multi-peak time-over-threshold and the hit position along the strip of the charged particle is investigated. Implementation of the off-line data calibration method is discussed in detail. Results and conclusion The overall time resolution for pions with momentum around 0.8 GeV/c is about 65 ps.

“…Since we are studying a case where the photon resolution is poor compared to the charged particle resolution, the final state charged particles (π + , π − and p) are folded with 1% resolution [16,17] in the momentum components to simulate a detectorlike effect, whereas 6% resolution is used for the photons. There are experiments that suffer from poor photon resolution for which 6% is rather an underestimation [18].…”

Precise measurement of the Dalitz plot parameters of the η → η π + π − decay gives a better insight of the dynamics of the heavy pseudo-scalar meson. Various measurements of the Dalitz plot parameters of the η meson have been performed with the detection of all the final state particles including the neutral decay of η → 2γ. In many experiments, reconstruction of the η meson from the neutral decay modes comes with the disadvantage of poor resolution and low efficiency compared to that of the charged particles. In this article, a study of the Dalitz plot parameters keeping the η meson as a missing particle is presented. The method is found to be advantageous in the case of poor photon resolution. Effect of the charged particle resolution on the Dalitz variable Y is also examined. This work may provide guidance to select a suitable method for the Dalitz plot analysis, depending on the detector resolution.
