We have carried out fits to the energy dependence of the ${P}_{11}$ partial-wave amplitude as obtained in two different single-energy analyses of $\ensuremath{\pi}\ensuremath{-}N$ scattering data. Data on inelastic cross sections were also used. The

A recent general analysis of light-baryon isospin splittings is updated and extended to charmed baryons. The measured $\Sigma_c$ and $\Xi_c$ splittings stand out as being difficult to understand in terms of two-body forces alone. We also discuss heav

We consider a model for the condensation of fermion pairs interacting through a generalized Coulomb potential. The model gives a new outlook on chiral condensation and chiral-symmetry breaking. For strong coupling, this model exhibits a new dynamical

The influence of the Coulomb interaction in states containing massless and flavorless fermionantifermion pairs is studied, using a continuum formulation within the finite volume ${S}^{3}$. Several different forms for the Coulomb interaction are exami

In this paper we develop a formalism for inclusion of fermions in a discussion of QCD on a hypersphere. We apply this to the study of the Coulomb energy operator. We use operators formed from pairs of fermion operators to construct a set of states fo

Using a polyspherical approximation, we formulate the φ4 theory on the hypersphere S3. It is shown that this model, in 3 + 1 space-time dimensions, is consistent with being free when the momentum cut-off is large.

We have carried out a partial-wave analysis of amalgamated pion-nucleon scattering data at 35 momenta in the range 0.429-1.995 GeV/c. At each momentum, a large set of fits was obtained, with the amplitude represented as the sum of a fixed background

Baryon SU/sub 6/ x O/sub 3/ supermultiplet masses are calculated in a model of three relativistic quarks bound by linear plus Coulomb-type potentials. Predictions of the model are in good agreement with known multiplet masses, except for the (56,1/su

We have analyzed K+p cross-section and polarization data in the momentum range 0.78–2.53 GeV/c. Single energy fits were made using an ACE parametrization which had no cutoff in J, was analytic and had Regge-asymptotic behavior in the cut cos θ pla

We present a series of numerical and statistical techniques for interpolating and combining (''amalgamating'') data from meson-nucleon scattering experiments. These techniques have been extensively applied to ..pi..p elastic and charge-exchange diffe
