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…
Thermodynamics of Quasi-Particles at Finite Chemical Potential
F. G. Gardim, F. M. Steffens
We present in this work a generalization of the solution of Gorenstein and Yang to the inconsistency problem of thermodynamics for systems of quasi-particles whose masses depend on…
Target mass corrections revisited
F. M. Steffens, W. Melnitchouk
We propose a new implementation of target mass corrections to nucleon structure functions which, unlike existing treatments, has the correct kinematic threshold behavior at finite…
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 Flavor Asymmetry of the Nucleon Sea
F. M. Steffens, A. W. Thomas
We re-examine the effects of anti-symmetry on the anti-quarks in the nucleon sea arising from gluon exchange and pion exchange between confined quarks. While the effect is primaril…
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…
