A model in which the soft collisions of the nucleon are described in terms of interactions of its two constituents (a quark and a diquark) is proposed. When adjusted to describe precisely the elastic proton-proton scattering data and supplemented with the idea of wounded constituents, the model accounts rather well for the centrality dependence of particle production in the central rapidity reg...

Parity-conserving and -violating response functions are computed for the inclusive electroexcitation of the N∗(1440) (Roper) resonance in nuclear matter modeled as a relativistic Fermi gas. Using various empirical parameterizations and theoretical models of the N −N∗(1440) transition form factors, the sensitivity of the response functions to details of the structure of the Roper resonance is in...

The generalized Goldberger-Treiman relation is combined with the Dashen-Weinstein sum rule to provide a constraint equation between the gKΣN and gKΛN coupling constants. A comprehensive examination of the published phenomenological and theoretical hyperon couplings has yielded a much smaller set of values, spanning the intervals 0.80 ≤ gKΣN/ √ 4π ≤ 2.72 and −3.90 ≤ gKΛN/ √ 4π ≤ −1.84, consisten...

The Baldin sum rule for the nucleon has been recalculated at the light of the most recent photoabsorption cross section measurements. The proton value (α + β) p = 13.69 ± 0.14 is smaller but consistent with the one usually quoted in literature. However, the value for the neutron (α + β) n = 14.40 ± 0.66 turns out to be three standard deviations away from the previously calculated one.
