Parton distributions in the presence of target mass corrections
F. M. Steffens, M. D. Brown, W. Melnitchouk +1
We study the consistency of parton distribution functions in the presence of target mass corrections (TMCs) at low Q^2. We review the standard operator product expansion derivation…
Running couplings for the simultaneous decoupling of heavy quarks
Steven D. Bass, R. J. Crewther, F. M. Steffens +1
Scale-invariant running couplings are constructed for several quarks being decoupled together, without reference to intermediate thresholds. Large-momentum scales can also be inclu…
Effect of bound nucleon internal structure change on nuclear structure functions
K. Tsushima, K. Saito, F. M. Steffens
Effect of bound nucleon internal structure change on nuclear structure functions is investigated based on local quark-hadron duality. The bound nucleon structure functions calculat…
Quark Distributions in a Medium
F. M. Steffens, A. W. Thomas, K. Tsushima
We derive the formal expressions needed to discuss the change of the twist-two parton distribution functions when a hadron is placed in a medium with relativistic scalar and vector…
The Role of Strange and Charm Quarks in the Nucleon Spin Structure Function
F. M. Steffens, A. W. Thomas
We perform an analysis of the relation between the factorization scale and the masses of the quarks in the calculation of the hard gluon coefficient in polarized deep inelastic sca…
A Study of Structure Functions for the Bag Beyond Leading Order
F. M. Steffens, A. W. Thomas
There has recently been surprising progress in understanding the spin and flavor dependence of deep inelastic structure functions in terms of the same physics needed in the simple…
