Hyp-StraMeeting 20220203

Strategy Meeting

Info

• 21:00- on Feb 03, 2022 (JST)
• Franco, Mark, Nue, Liguang, Guido, Joerg, Pete, Sho, Gogami
• via Zoom

Discussion (1)

• Possibility of HKS in Hall C (c.f. Collaboration Meeting 2021)
  • Kinematics difference between Hall A and C.
    Larger energy in Hall A which leads to a better S/N, but worse resolution.
  • Three cases are being studied, A: PCS+HKS+SHMS, B: PCS+HKS+HES, C: SPL+HKS+HES.
    → Solid angle / momentum resolution were shown after Q strength were adjusted for the B and C option.

• Beam time
  • When ?
    → Could be in 2026~ even in Hall C.
  • Moller 2024. SBS is being tried to be done before that.
    → HKS would be in 2029~ in the case of Hall A.
  • Could HRS-HRS (hyper) be jumped in (in 2024? for example)?
    → HRS-HKS could take a similar time to install.
  • Can be longer ?
    
    

→ 1. HRS-HKS in Hall A (2024?), 2. XXX-HKS in Hall C (2026~), 3. quick HRS-HRS(HKS) experiment (+ α later) in Hall A

• PAC

Report

• Information to share
  • PCS status (Nue, Sho)
    • Feb 6 (Newport News)
    • will be unloaded in ESB
  • Hall A / C simulation (Sho, Nue)

Discussion (2)

• Draft prepared (nnΛ)
  • Significance calculation → Bishnu will send us how he obtained the result.
  • Nue will ask Harada san for his opinions.

• Presentations in Hall A Winter Collaboration meeting
  • Toshi: nnΛ
  • Guido: HKS
