Leading Chiral Contributions to the Spin Structure of the Proton
Jiunn-Wei Chen, Xiangdong Ji
The leading chiral contributions to the quark and gluon components of the proton spin are calculated using heavy-baryon chiral perturbation theory. Similar calculations are done fo…
Baryons in Partially Quenched Chiral Perturbation Theory
Jiunn-Wei Chen, Martin J. Savage
We include the lowest-lying octet- and decuplet-baryons into partially quenched chiral perturbation theory. Perturbing about the chiral limit of the graded SU(6|3)_L x SU(6|3)_R fl…
Matrix Elements of Twist-2 Operators in Quenched Chiral Perturbation Theory
Jiunn-Wei Chen, Martin J. Savage
We compute the leading non-analytic quark mass dependence of the matrix elements of isovector twist-2 operators between octet baryon states in quenched QCD using quenched chiral pe…
Constructing Parton Convolution in Effective Field Theory
Jiunn-Wei Chen, Xiangdong Ji
Parton convolution models have been used extensively in describing the sea quarks in the nucleon and explaining quark distributions in nuclei (the EMC effect). From effective field…
Large-N_c Quark Distributions in the Delta and Chiral Logarithms in Quark Distributions of the Nucleon
Jiunn-Wei Chen, Xiangdong Ji
In a world with two quark flavors and a large number of colors (N_c), the polarized and unpolarized quark distributions in the delta are completely determined by those in the nucle…
Is the Sullivan Process Compatible with QCD Chiral Dynamics?
Jiunn-Wei Chen, Xiangdong Ji
We calculate the leading non-analytic quark-mass dependence in the moments of isovector quark distributions using heavy-baryon chiral perturbation theory. The results differ from t…
