| |
| − | The idea is to compare the outbending (B<0) <math> \pi^-</math> rate in paddle 27 to the inbending(B>0) <math>\pi^-</math> rate in paddle 7 when 1 < <math>Q^2</math> < 2. For the same kinematics the rates should be the same because the reaction is the same. Do the same for <math>\pi^+</math> to see if it is consistent. This will show much flipping the magnet polarity impacts the rate measurement. Are the differences due to the B-field change or the scintillator efficiency, or to the track reconstruction? Our goal is to argue that the detector has the same efficiency for detecting <math>\pi^-</math> and <math>\pi^+</math> in the same scintillator when the Torus B-field direction is flipped.

For inbending data, loss of electrons were at acceptable level. To gain some electrons back we generated new cut parametes that will specifically work better for outbending data. Also we slightly adjusted the cut parameters for inbending data for some sectors and segments."

Are the ratio's from rates normalized with beam current measured by the FC?
Is the conclusion that the NH3 and ND3 rates are indistinguishable?
1.) Overlap electron kinematic ([math]\theta[/math], W, Momentum) for B>0 and B<0 and ND3 and NH3.
(NH3,B>0), (NH3,B<0), (ND3,B>0) && (ND3,B<0)
 |
 |
|
| Electron Momentum((NH3,B>0), (NH3,B<0), (ND3,B>0) && (ND3,B<0)) |
Electron [math]\theta[/math] Angle((NH3,B>0), (NH3,B<0), (ND3,B>0) && (ND3,B<0)) |
W mass((NH3,B>0), (NH3,B<0), (ND3,B>0) && (ND3,B<0))
|
2.) Now plot ratio (B< 0/B>0) electron kinematic ([math]\theta[/math], W, Momentum) for ND3 and NH3. ( I expect 2 curves in one plot)
[math]\frac{ND3 B\lt 0}{ND3 B\gt 0}[/math], [math]\frac{NH3 B\lt 0}{NH3 B\gt 0}[/math]
 |
 |
|
| Electron Momentum([math]\frac{ND3 B\lt 0}{ND3 B\gt 0}[/math], [math]\frac{NH3 B\lt 0}{NH3 B\gt 0}[/math]) |
Electron [math]\theta[/math] Angle([math]\frac{ND3 B\lt 0}{ND3 B\gt 0}[/math], [math]\frac{NH3 B\lt 0}{NH3 B\gt 0}[/math]) |
W mass([math]\frac{ND3 B\lt 0}{ND3 B\gt 0}[/math], [math]\frac{NH3 B\lt 0}{NH3 B\gt 0}[/math])
|
2.) Target ratio (B< 0/B>0) Difference electron kinematic ([math]\theta[/math], W, Momentum) (Ration for ND3 target - Ratio for NH3 target). ( I expect 1 curves in one plot)
[math]\frac{ND3 B\lt 0}{ND3 B\gt 0} - \frac{NH3 B\lt 0}{NH3 B\gt 0}[/math]

|
| Electron Momentum ([math]\frac{ND3 B\lt 0}{ND3 B\gt 0} - \frac{NH3 B\lt 0}{NH3 B\gt 0}[/math]) |
[math]\theta[/math] Theta Angle([math]\frac{ND3 B\lt 0}{ND3 B\gt 0} - \frac{NH3 B\lt 0}{NH3 B\gt 0}[/math]) |
