Abstract

We have measured the proton and deuteron spin structure functions g{sup p}{sub 1} and g{sup d}{sub 1} in the region of the nucleon resonances for W{sup 2}{lt}5 GeV{sup 2} and Q{sup 2}{approx_equal}0.5 and Q{sup 2}{approx_equal}1.2 GeV{sup 2} by inelastically scattering 9.7 GeV polarized electrons off polarized {sup 15}NH{sub 3} and {sup 15}ND{sub 3} targets. We observe significant structure in g{sup p}{sub 1} in the resonance region. We have used the present results, together with the deep-inelastic data at higher W{sup 2}, to extract {Gamma}(Q{sup 2}){equivalent_to}0=g{sub 1}(x,Q{sup 2})dx. This is the first information on the low-Q{sup 2} evolution of {Gamma} toward the Gerasimov-Drell-Hearn limit at Q{sup 2}=0. {copyright} {ital 1997} {ital The American Physical Society}

Measurement of Spin Structure Function G(1) for Proton and Deuteron in the Resonance Region

Technical Report Raines, P

Experiment E143 at SLAC measured the proton and deuteron spin structure functions g{sub 1}{sup p}, g{sub 2}{sup p}, g{sub 1}{sup d} and g{sub 2}{sup d} using polarized electrons at beam energies of 29, 16, and 9.7 GeV incident on polarized {sup 15}NHY{sub 3} and {sup 15}ND{sub 3} targets. Two spectrometers detected the scattered electrons at the angles 4.5{sup o} and 7.0{sup o}, covering a kinematic range of x > 0.03 and 0.3 < Q{sup 2} < 10 GeV{sup 2}. Data taken at 9.7 GeV contain information on the nucleon resonances (W{sup 2} < 4 GeV{sup 2}) at Q{sup 2} {approx}more »« less

What can we learn from the recent measurements of the spin-dependent structure function [ital g][sub 1]([ital x])

Journal Article Li, Z - Physical Review, D (Particles Fields); (United States)

In this paper, we argue that the effects of the Drell-Hearn-Gerasimov (DHG) sum rule should be included to extract the sum rule of polarized neutrons from the recent Spin Muon Collaboration measurement of the spin-dependent structure function [ital g][sub 1]([ital x]) of the deuteron, since the measurement was obtained at fairly low [ital Q][sup 2]. The value [Gamma][equivalent to][integral][sub 0][sup 1][ital g][sub 1]([ital x])[ital dx] could be modified significantly at [ital Q][sup 2] around 2--4 GeV[sup 2] by the high twist effects connected with the DHG sum rule.

Measurement of Inclusive Spin Structure Functions of the Deuteron with CLAS

Journal Article Yun, J

We report the results of a new measurement of spin structure functions of the deuteron in the region of moderate momentum transfer (Q{sup 2} = 0.27 -- 1.3 (GeV/c){sup 2}) and final hadronic state mass in the nucleon resonance region (W = 1.08 -- 2.0 GeV). We scattered a 2.5 GeV polarized continuous electron beam at Jefferson Lab off a dynamically polarized cryogenic solid state target ({sup 15}ND{sub 3}) and detected the scattered electrons with the CEBAF Large Acceptance Spectrometer (CLAS). From our data, we extract the longitudinal double spin asymmetry A{sub {parallel}} and the spin structure function g{sub 1}{supmore »« less

Measurement of the $Q^{2}$ Dependence of the Deuteron Spin Structure Function $g_{1}$ and its Moments at Low $Q^{2}$ with CLAS

Journal Article Adhikari, K.; Deur, A.; El Fassi, L.; ... - Physical Review Letters

We measured the g(1) spin structure function of the deuteron at low Q(2), where QCD can be approximated with chiral perturbation theory (chi PT). The data cover the resonance region, up to an invariant mass of W approximate to 1.9 GeV. The generalized Gerasimov-Drell-Hearn sum, the moment Gamma(d)(1) and the spin polarizability gamma(d)(0) are precisely determined down to a minimum Q(2) of 0.02 GeV2 for the first time, about 2.5 times lower than that of previous data. We compare them to several chi PT calculations and models. These results are the first in a program of benchmark measurements of polarizationmore » observables in the chi PT domain.« less

Spin Structure Functions of the Deuteron Measured with CLAS in and above the Resonance Region

Thesis/Dissertation Dharmawardane, Kahanawita

Spin structure functions of the nucleon in the region of large x and small to moderate Q² continue to be of high current interest. The first moment of the spin structure function g₁, γ₁, goes through a rapid transition from the photon point (Q²=0), where it is constrained by the Gerasimov-Drell-Hearn sum rule, to the deep inelastic limit where it is sensitive to the nucleon spin fraction carried by quarks. The interesting behavior in the transition region is dominated by baryon resonance excitations. We concluded an experiment to measure these observables for deuterium as part of the ''EG1'' run groupmore »« less
