Electromagnetic contribution to charge symmetry violation in parton distributions
X. G. Wang, A. W. Thomas, R. D. Young
We report a calculation of the combined effect of photon radiation and quark mass differences on charge symmetry violation (CSV) in the parton distribution functions of the nucleon…
The spin of the proton in chiral effective field theory
Hongna Li, P. Wang, D. B. Leinweber +1
Proton spin is investigated in chiral effective field theory through an examination of the singlet axial charge, , and the two non-singlet axial charges, and . Fini…
On the smallness of the cosmological constant in SUGRA models with Planck scale SUSY breaking and degenerate vacua
C. Froggatt, R. Nevzorov, H. B. Nielsen +1
We argue that the exact degeneracy of vacua in N=1 supergravity can shed light on the smallness of the cosmological constant. The presence of such vacua, which are degenerate to ve…
SU(3) breaking in hyperon transition vector form factors
P. E. Shanahan, A. N. Cooke, R. Horsley +6
We present a calculation of the SU(3)-breaking corrections to the hyperon transition vector form factors to in heavy baryon chiral perturbation theory with finit…
E6 inspired composite Higgs model
R. Nevzorov, A. W. Thomas
We consider a composite Higgs model embedded into a Grand Unified Theory(GUT) based on the E_6 gauge group. The phenomenological viability of this E_6 inspired composite Higgs mode…
Pure sea-quark contributions to the magnetic form factors of baryons
P. Wang, D. B. Leinweber, A. W. Thomas
We propose the pure sea-quark contributions to the magnetic form factors of baryons, and , as priority observables for the examination of sea-quark contr…
