We present a calculation of the lowest-lying baryon masses in the quenched approximation to QCD. The calculations are performed using a non-perturbatively improved clover fermion action, and a splitting is found between the masses of the nucleon and its parity partner. An analysis of the mass of the first radial excitation of the nucleon finds a value considerably larger than that of the parity...

This communication is based on a retrospective survey of 245 intraocular foreign bodies (IOFB) seen at the Birmingham and Midland Eye Hospital between I96I and I970 inclusive. Because the numbers have been swollen by patients referred from other regions after failed extraction, the results are not strictly comparable with those of other authors, as there tends to be a higher rate of complicatio...

We investigate the properties of interference fragmentation functions arising from the emission of two leading hadrons inside the same jet for inclusive leptonnucleon deep-inelastic scattering. Using an extended spectator model for the mechanism of the hadronization, we give a complete calculation and numerical estimates for the examples of a proton-pion pair produced with invariant mass on the...

We compute a shift of baryon mass spectra due to quark masses in perturbation, in Sakai-Sugimoto model of holographic QCD. We find the shift for the ground state nucleons to be δM = 4.1 mπ GeV , which is consistent with the current lattice QCD result. We predict the same value of the shift for N(1535) and ∆, while a larger value 7.7 mπ GeV −1 for Roper N(1440). We also present some evidences th...

We calculate the difFerential cross section and the photon asymmetry of the reaction pd m x d for incident photon energies below 1 GeV and compare with data at 8 = 130'. Our formalism, based on the spectator-on-mass-shell approximation, is fully relativistic and uses the de% vertex of Buck and Gross and a recently developed model for the elementary 7N -+ xN amplitude that describes well the fir...

The properties of the proton has been investigated considering a proton as diquark-quark system. A model for diquark has been suggested in an analogy with the quasi-particle in a crystal lattice. The mass of the diquark obtained in the present model has been found to be in good agreement with other theoretical predictions. The binding energy of proton, compressibility and excitation energy for ...

The first two components of this strategy require active community involvement. Community members must have access to primary health clinics where qualified health professionals with adequate tools can provide timely and accurate diagnosis and treatment. These health professionals must also ensure that mosqu i to nets a re p roper l y placed, used correctly, maintained in good repair, and broug...
