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.
- Multiple scattering with lower momentum is different.
