Evolution of Parton Fragmentation Functions at Finite Temperature
Jonathan A. Osborne, Enke Wang, Xin-Nian Wang
The first order correction to the parton fragmentation functions in a thermal medium is derived in the leading logarithmic approximation in the framework of thermal field theory. T…
Multiple Parton Scattering in Nuclei: Twist-Four Nuclear Matrix Elements and Off-Forward Parton Distributions
Jonathan Osborne, Xin-Nian Wang
Multiple parton scatterings inside a large nucleus generally involve higher-twist nuclear parton matrix elements. The gluon bremsstrahlung induced by multiple scattering depends no…
A Study of Nucleon Spin Struture from Quantum Chromodynamics
Jonathan Osborne
I present an introduction to the field of Quantum Chromodynamics (QCD) with emphasis on nucleon spin structure and perturbative methods. After a somewhat comprehensive overview of…
An Analysis of the Next-to-Leading Order Corrections to the g_T(=g_1+g_2) Scaling Function
Xiangdong Ji, Jonathan Osborne
We present a general method for obtaining the quantum chromodynamical radiative corrections to the higher-twist (power-suppressed) contributions to inclusive deep-inelastic scatter…
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…
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…
Generalized Drell-Hearn-Gerasimov Sum Rule at Order {\cal O}(p^4) in Chiral Perturbation Theory
Xiangdong Ji, Chung-Wen Kao, Jonathan Osborne
We calculate the forward spin-dependent photon-nucleon Compton amplitudes and as functions of photon energy and mass at the next-to-leading ()…
The Nucleon Spin Polarizability at Order ) in Chiral Perturbation Theory
Xiangdong Ji, Chung-Wen Kao, Jonathan Osborne
We calculate the forward spin-dependent photon-nucleon Compton amplitude as a function of photon energy at the next-to-leading () order in chiral perturbation theory…
Generalized Sum Rules for Spin-Dependent Structure Functions of the Nucleon
Xiangdong Ji, Jonathan Osborne
The Drell-Hearn-Gerasimov and Bjorken sum rules are special examples of dispersive sum rules for the spin-dependent structure function G_1(ν, Q^2) at Q^2=0 and \infty. We generaliz…
Simplification of Higher-Twist Evolution in the Large N_c Limit: Why and Why Not
Xiangdong Ji, Jonathan Osborne
Working in the light-cone gauge, we find a simple procedure to calculate the autonomous one-loop Q^2 evolution of the twist-three part of the nucleon g_T(x, Q^2) structure function…
One-Loop Corrections and All Order Factorization In Deeply Virtual Compton Scattering
Xiangdong Ji, Jonathan Osborne
We calculate the one-loop corrections to a general off-forward deeply-virtual Compton process at leading twist for both parton helicity-dependent and independent cases. We show tha…
One-Loop QCD Corrections to Deeply Virtual Compton Scattering: The Parton Helicity-Independent Case
Xiangdong Ji, Jonathan Osborne
We show that the one-loop QCD correction to deeply-virtual Compton scattering can be factorized into the finite perturbative contributions and the collinearly-divergent terms, whic…
