We report the exclusive photoproduction cross sections for the Σ 0 (1385), Λ(1405), and Λ(1520) in the reactions γ + p → K + + Y * using the CLAS detector for energies from near the respective production thresholds up to a center-of-mass energy W of 2.85 GeV. The differential cross sections are integrated to give the total exclusive cross sections for each hyperon. Comparisons are made to curre...
I investigate band and Mott insulating states in a two-band Hubbard model, with the aim of understanding the differences between the idealised oneorbital model and the more realistic multi-band case. Using a projection ansatz I show that additional orbitals suppress the metal-insulator transition, leading to a critical coupling of approximately eight times the bare band-width. I also demonstrat...
PURPOSE Circumcision is one of the historical surgical procedures. Some sources throughout the history contain various definitions about different circumcision methods. we described the details of the method, and aimed to remind the possibility of contemporary usage. MATERIALS AND METHODS We compared circumcision chapters of Sabuncuoglu and Zahrawi to explain the historical origin of Sabuncuo...
In these lectures I make an introduction to chiral unitary theory applied to the meson baryon interaction and show how several well known resonances are dynamically generated, and others are predicted. Two very recent experiments are analyzed, one of them showing the existence of two Λ(1405) states and the other one providing support for the Λ(1520) resonance as a quasibound state of Σ(1385)π. ...
The effects of the pumping wavelength and their power on the gain flattening of a fiber Raman amplifier (FRA) are investigated. The multi-wavelength pumping scheme is utilized to achieve gain flatness in FRA. It is proposed that gain flatness becomes better with increase in number of pumping wavelengths applied. We have achieved flat gain with 0.27 dB fluctuation in a spectral range of 1475-160...
We perform an evaluation of the p-wave amplitudes of mesonbaryon scattering in the strangeness S = −1 sector starting from the lowest order chiral Lagrangians and introducing explicitly the Σ∗ field with couplings to the meson-baryon states obtained using SU(6) symmetry. The N/D method of unitarization is used, equivalent, in practice, to the use of the Bethe-Salpeter equation with a cut-off. T...
