NnL analysis 20210611

JLab Hypernuclear Meeting

Info

• 9:30-10:30 a.m. on June 11, 2021 (JST)
• Participants: Bishnu, Nathaniel, Toshi Gogami
• via BlueJeans

Bishnu

• About the angle resolution in the nnΛ experiment
  • Hole size + angle resolution
  • The angle resolution that he estimated will be used for the A dependence of the missing mass resolution.

• Simulation spectrum for the Al data
  • The number of counts was estimated assuming the cross section if 100 nb/sr.
  • Simulated spectrum was made with width assumptions of σ = 0.5 and 1.0 MeV.
    He will check if the width assumptions are reasonable once the new A dependence is evaluated.

Nathaniel

• Energy loss correction, Multiple scattering effect in target
  • Multiple scattering with lower momentum is different.
    He is going to check if the difference is reasonable by estimating it by hand calculation.
  • Energy loss MPV as a function of x' was obtained in TARG simulation.
    → The width became about σ = 100 keV from 200 keV for the particles from the main body of the cell.

Next Meeeting
