Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Physics, 2013.
In title on title-page, "[square root of]" appears as the mathematical symbol. Title as it appears in MIT degrees awarded booklet, February 2013: Measurement of double longitudinal spin asymmetry of Jet-[pi] +/- correlations in polarized proton-proton collisions at [square root of] s=200 GeV RHIC Cataloged from PDF version of thesis.
Includes bibliographical references (p. 81-83).
Inclusive measurements from polarized proton-proton collisions at RHIC have constrained [Delta]g, the polarized gluon distribution function of the proton. Correlation observables, such as this pion+jet measurement, allow for reconstruction of initial parton kinematics and are thus sensitive to the x dependence of [Delta]g. By measuring charged pions opposite a jet, this particular measurement can be sensitive to the flavor of the struck parton. This measurement, which is dominated by the quark-gluon subprocess, can be divided into terms proportional to [Delta]u[Delta]g and [Delta]d[Delta]g. The relatively larger quark polarization amplifies the measured asymmetry thereby enhancing the statistical power. This thesis presents the result of the mid-rapidity pion+jet longitudinal double spin asymmetry analysis from 10.6 pb-1 of luminosity collected in the 2009 200 GeV p+p run.

<Abstract>Inclusive measurements from polarized proton-proton collisions at RHIC have constrained [Delta]g, the polarized gluon distribution function of the proton. Correlation observables, such as this pion+jet measurement, allow for reconstruction of initial parton kinematics and are thus sensitive to the x dependence of [Delta]g. By measuring charged pions opposite a jet, this particular measurement can be sensitive to the flavor of the struck parton. This measurement, which is dominated by the quark-gluon subprocess, can be divided into terms proportional to [Delta]u[Delta]g and [Delta]d[Delta]g. The relatively larger quark polarization amplifies the measured asymmetry thereby enhancing the statistical power.
