3He(e,e'd) Asymmetries

Transverse Proton asymmetries as function of BB momentum

Asymmetry as a function of BB Momentum (with different cuts)

Similar to results from last week. It seems that asymmetries depend on the BigBite momentum acceptance. I considered Student's test to statistically test my Hypothesis.

Asymmetry as a function of |\vec q| = 0.58 +/- 0.01

I have also checked how asymmetry changes when I do a cut on the magnitude of a q-vector. It seems that my cut had no effect.

12.) 13.) 14.)

Asymmetry with cut on |\vec q| direction

I have also checked how asymmetry changes when I do a cut on a direction of a q-vector. It seems that this cut also had no effect.

Approximate asymmetries Ax' and Az':

Using mean direction of a q-vector (approx. 67deg) and considering a (large) error on this angle (approx. 10deg), I rotated my transverse (Ax) and longitudinal (Az) asymmetries from Hall-CS to q-CS and determined asymmetries Ax' and Az'. When doing my calculation I also considered proper error propagation. It seems that error in theta-q affects my results only and large and small missing masses.
