Key Issues in Hadronic Physics
Simon Capstick, Steven Dytman, Roy Holt +3
A group of fifty physicists met in Duck, NC, Nov. 6-9 to discuss the current status and future goals of hadronic physics. The main purpose of the meeting was to define the field by…
Counting Form Factors of Twist-Two Operators
Xiangdong Ji, Richard F. Lebed
We present a simple method to count the number of hadronic form factors based on the partial wave formalism and crossing symmetry. In particular, we show that the number of indepen…
Parity-Violating Pion-Nucleon Coupling h_{πNN}^{(1)} from π^+ Electroproton Production Near the Threshold
Jiunn-Wei Chen, Xiangdong Ji
We study the possibility of measuring parity-violating pion-nucleon coupling h_{πNN}^{(1)} from π^+ electroproton production in the threshold region. We calculate the electron-heli…
Residual Chiral Symmetry Breaking in Domain-Wall Fermions
Chulwoo Jung, Robert G. Edwards, Xiangdong Ji +1
We study the effective quark mass induced by the finite separation of the domain walls in the domain-wall formulation of chiral fermion as the function of the size of the fifth dim…
The Singlet g_2 Structure Function in the Next-to-Leading Order
A. V. Belitsky, Xiangdong Ji, Wei Lu +1
Following a previous study of the one-loop factorization of the nonsinglet structure function of the nucleon, we present in this paper the next-to-leading order coefficient f…
Residual Chiral Symmetry Breaking in Domain-Wall Fermions
Chulwoo Jung, Valeriya Gadiyak, Xiangdong Ji +1
We study the effective quark mass induced by the finite separation of the domain walls in the domain-wall formulation of chiral fermion as the function of the size of the fifth dim…
One-Loop Factorization of the Nucleon g_2-Structure Function in the Non-Singlet Case
Xiangdong Ji, Wei Lu, Jonathan Osborne +1
We consider the one-loop factorization of the simplest twist-three process: inclusive deep-inelastic scattering of longitudinally-polarized leptons on a transversely-polarized nucl…
Domain-Wall Induced Quark Masses in Topologically-Nontrivial Background
Valeriya Gadiyak, Xiangdong Ji, Chulwoo Jung
In the domain-wall formulation of chiral fermion, the finite separation between domain-walls () induces an effective quark mass () which complicates the chiral li…
