TL;DR: In this article, it was shown that the EMC enhancement in the region x < 0.3 can be explained by an increase in the pion field in iron if there is an attractive force which mixes nucleon-hole and delta-hole states at momenta of order 300-400 MeV/c.

TL;DR: In this article, it was shown that deep inelastic scattering data provide a very strong bound (5.0±1.5%) on the fraction of the momentum of the nucleon which is carried by pions.
215 citations
TL;DR: In this article, the authors used the cloudy bag model to calculate the pion coupling to the strange members of the nucleon octet (and delta decuplet) and then calculated the magnetic moments of all members, including lowest-order pionic corrections.
88 citations
TL;DR: In this article, the influence of pionic corrections on multi-quark hadrons was investigated and the implications of these corrections on six quark configurations were discussed. And the bag parameters from ordinary baryons and mesons were determined.
Abstract: The authors investigate the influence of pionic corrections on multi-quark hadrons. After determining the bag parameters from ordinary baryons and mesons, they discuss the implications for six-quark configurations.

TL;DR: The axial form factor of the nucleon in the Cloudy Bag Model is harder than the NNπ vertex function, and consistent with data for a bag radius about 1 fm.
39 citations
TL;DR: In this article, a separable potential model is constructed to describe the coupled Σ N- Λ N systems including Pauli effects, and the momentum-space Schrodinger equation is solved self-consistently for the complex eigenvalues of 1s and 1p state light (A ⩽ 16) Σ ° hypernuclei.

TL;DR: In this paper, the authors generalise an earlier bound on the virtual-pion content of the physical nucleon to include momentum conservation through the non-relativistic recoil of the baryon core.
Abstract: The authors generalise an earlier bound on the virtual-pion content of the physical nucleon to include momentum conservation through the non-relativistic recoil of the baryon core. In addition, they discuss the possibility, and physical meaning, of obtaining such a bound for virtual rho mesons.

TL;DR: In this article, it was shown that nucleon pole terms contribute significantly to proton decay, increasing the branching ratio for e+π0 and νRπ+ modes, and decreasing the total lifetime to the point where keeping the SU(5) value of the lifetime below the experimental upper bound forces us to the choice of QCD scale parameter and proton radius parameter which are near the edge of the allowed region.
