Title | Measurement of the Elastic Ep Cross Section at Q2 = 0.66, 1.10, 1.51 and 1.65 Gev2 | ||||
Abstract | The nucleon form factors have been investigated by physicists for decades because of their fundamental importance. The world data of the proton magnetic form factor GMp has been focused on Q2 lower than 5 GeV2 and they have large uncertainties at higher Q2. Jefferson Lab experiment E12-07-108 aims to improve the accuracy of the e ? p elastic cross section to better than 2% over a Q2 range of 7 ? 14 GeV2. From 2015 to 2016, the e ? p elastic cross section was measured over a wide range of Q2 from 0.66 ? 12.56 GeV2 at the Thomas Jefferson National Accelerator Facility in Virginia, USA. An unpolarized electron beam was scattered o? a cryogenic hydrogen target and the scattered electron was detected in the high resolution spectrometers. This thesis focuses on the cross section calculations of the data taken in the spring of 2015, where Q2 = 0.66, 1.10, 1.51 and 1.66 GeV2. At Q2 = 0.66 GeV2, an uncertainty < 3% was achieved and < 5% was achieved for the other three Q2 at the moment. The re | ||||
