As one can see from histograms of the pion_theta_angle_vs_phi_angle_in_CM_Frame and the electron_theta_angle_vs_phi_angle_in_CM_Frame, the pion and electron acceptance in the region of <math>\phi_{diff}^{CM}=180</math> is nearly zero(significantly low).

==SIDIS Analysis==

a.) Cross-Section comparison

i.) Calculate absolute cross section for <math>\cos(\theta_{pi})</math> = 0.5, 1 < Q^2 < 4 GeV^2 , W = 1.45 +/- 0.2 GeV

<math>\frac{d \sigma}{d \Omega^*_{\pi}} = \frac{1.061 \times 10^{-3} [\mu barn]}{0.88} = 0.0012 \ne 2.4</math>?

;Documentation 

The five-fold differential cross section for single pion production is equal to the following: 

:::<math>\frac{\partial^5 \sigma}{\partial E_f \partial \Omega_e \partial {\Omega_{\pi}}^*} = \frac{1}{2 \pi} \Sigma \frac{1}{L_{int} A_{cc} \epsilon_{CC} \Delta W \Delta Q^2 \Delta cos {\theta_{\pi}}^* {\phi_{\pi}}^*} \frac{d(W, Q^2)}{d(E_f, cos \theta_e)}</math> 

The Jacobian term can be given as: 

:::<math>\frac{d(W, Q^2)}{d(E_f, cos \theta_e)} = \frac{2 M_p E_i E_f}{W}</math> 

:::<math>\frac{\partial^5 \sigma}{\partial E_f \partial \Omega_e \partial {\Omega_{\pi}}^*} = \Gamma_{v}\times \frac{d^2 \sigma}{d {\Omega_{\pi}}^*}</math> 

where <math>\Gamma_{v}</math> is the virtual photon flux and can be written as 

:::<math>\Gamma_{v} = \frac{\alpha}{2 \pi^2 Q^2} \frac{(W^2 - {M_p}^2)E_f}{2M_p E_e} \frac{1}{1-\epsilon}</math> 

:::<math>\epsilon = (1 + 2(1+\frac{{\nu}^2}{Q^2})tan^2 \frac{\theta_e}{2})^{-1}</math> 

The reason of having low cross section might be binning 

In paper they use the following number of bins: 

{| border="1" |cellpadding="20" cellspacing="0
|-
| Variable || Num. Bin || Range || Bin Size
|-
| W || 27 || 1.15 - 1.7 GeV || 20 MeV
|-
| <math>Q^2</math> || 7 || 1.1 - 5.0 <math>GeV^2</math> || variable
|-
| <math>cos {\theta_{\pi}}^*</math> || 10 || -1.0 - 1.0 || 0.2
|-
| <math>{\phi_{\pi}}^*</math> || 24 || -180. - 180 || 15
|} 
Number of bins in my case were 360. 

Number of bins equal is ~24 

[[Image:phi_angle_in_cm_frame_vs_cross_section_actual_one_cuts_on_MissingMass_W_cos_theta_0-5_nocut_onQsqr.jpg|400px]] 

When i applied <math>1.6<Q^2<1.84</math> cut, the number of entries were reduced to 152. 

In paper they use liquid-hydrogen unpolarized target(we have NH3 and ND3 polarized). The polarized electron beam current is 8 nA(in our case it is about 6 nA). and luminosity is different too. It also depends on statistics.

ii.) What is smallest angular coverage of EC (8 degrees?)
Determine phi region where there is no acceptance ( where should we stop plotting data)?

iii.) Asymmetry Calculation

a.) Beam Asymmetry Plot

In order to plot Beam Asymmetry we need to plot for the first time the histogram of the invariant_mass_vs_cross_section. Then determine the structure function fitting the cross section and calculating the beam asymmetry function which is given as : 

::::: <math>A_{TL^'} = \sqrt{2\epsilon (1 - \epsilon)} \sigma_{LT^'} \times sin{\phi_{\pi}}^*</math> 
for given cos(theta) of the pion in cm, Q^2 and W invariant mass. 

Choose kinematics ( a single theta and phi point )to max our stats and comparison to paper
Histogram the following

#Number of e-pi coincidence events, number of FC counts
# Number of e-pi coincidence events/FC counts
#Number of e-pi coincidence events/FC count/Pt

for groups of runs with h_e,P_t = ++, +-, -+, --

table with 4 columns of h_e, P_t and 3 rows of the above histograms

==SIDIS Analysis==

1.) make semi-inclusive spectrum:

a.) h>0 Pt>0
b.) h > 0 pt<0
c.)h<0 pt>0
d.)h<0 pt<0

2.) ad up opposite target polarization histograms

3.) subtract h> 0 and h<0

0.) insert run summarry table, Pb, Pt, PB*Pt, Btorus

1.) make semi-inclusive spectrum:

a.) h>0 Pt>0

b.) h > 0 pt<0

4.) unpolarized target asymmetry

Rebin asymmetry hisograms and combine the two into a total asymmetry histogram
