1. Single Pion Eletroproduction
SPE
Study of high resonances such as S11, D13, F15
with more deeper level analysis such as PWA
Purpose
Why ?
Only p data available for high kinematic region
(W,Q2)
talked to A. Waluyo
When ?
From now on
set up a time plan
How ?
1. More various theoretical approaches 2.
Combination with p0 and 2p data
Ultimate Goal !
depending on others analysis status
3
Single Quark Transition Model
EM transitions between all members of two
SU(6)xO(3) multiplets expressed as 4 reduced
matrix elements A,B,C,D.
Example
(D0)
Fit A,B,C to D13(1535) and S11(1520)
SU(6) Clebsch-Gordon
A3/2, A1/2
A,B,C,D
4
Single Quark Transition Model
(C-G coefficients and mixing angles)
5
Single Quark Transition Model Predictions for
56,0?70,1- Transitions
Proton

2. Single Pion Photoproduction
SPP
Observed cross section of single pion reaction
with photoproduction data
Purpose
Why ?
1. Only Electroproduction data for high
kinematic region (W,Q2)2. Ad1/2,Sd1/2 for
resonances
Who ?
Whoever is interested in
pp- ?
When ?
More detail time plan will be set up
two particle tracks ??
1. Diagnostic single pion channel with
photoproduction data (G10)2. Kinematic Study
(corrections/cuts)3. Involving Lus tracking
study (?)
How ?
discussion with mibe

3. EG3 Run Contribution
ERC
Purpose
Participate in detail subjects for EG3 analysis

• Based on understanding of the current stage

Interesting channels ?
3-1. Way
? Co-working with Zhiwen
Search possibility for improving particle
tracking
3-2. Way
? Co-working with Haiyun
????
3-3. Way
? Co-working with Lewis
10
3-1. Way
Searching for ?- - , ?0 ?

• What should be done before main analysis ?

What reaction channel is interesting ?
?? ?-p- ?-p

• Calibration will be completed soon (Pass1)

Need to be done in future
Calendar Oct. Nov. Dec.

• Eloss
• GSIM
• Kinematic fit
• Momentum correction
• Normalization

long run job
long run simulation
what we will do ?
priority ?
11
3-2. Way
Reconstruction efficiency ?

• Once tracking program working good ?

What is the effect of tracking tool for analysis ?

• GSIM simulation can be run independently

Need to be done in future
Calendar Oct. Nov. Dec.

• Eloss
• GSIM
• Kinematic fit
• Momentum correction
• Normalization

reaction channel cross check
One of main issues
what we will do ?
priority ?
12
3-3. Way
What is the goal ?

• Scratch the general procedure of analysis ?

• Be familiar with CLAS detector structure
  /software package

• What else ???

Need to be done in far future
Calendar Oct. Nov. Dec.

• Eloss
• GSIM
• Kinematic fit
• Momentum correction
• Normalization

Time plan is important
what we will do ?
priority ?
