Dispersion Relations and Inconsistency of Ρ Data
نویسنده
چکیده
The high energy elastic nucleon cross section is treated from the viewpoint of the basic principles of local field theory. The connection between the energy dependence of σtot and the ρ ratio of the real to imaginary parts of the forward elastic scattering amplitude is examined in the framework of dispersion relations, derivative dispersion relations and crossing symmetry.

Integral and derivative dispersion relations , analysis of the forward scattering data
Integral and derivative dispersion relations, analysis of the forward scattering data. Abstract. Integral and derivative dispersion relations (DR) are considered for the forward scattering pp and ¯ pp amplitudes. A new representation for the derivative DR, valid not only at high energy, is obtained. The data on the total cross sections for pp(¯ pp) interaction as well as the data on the paramet...

In this paper, we present a solid-core Silica-based photonic crystal fiber (PCF) composed of hexagonal lattice of air-holes and calculate the effective index and chromatic dispersion of PCF for different physical parameters using the empirical relations method (ERM). These results are compared with the data obtained from the conventional multipole method (MPM). Our simulation results reveal tha...
متن کاملThermal effects on ρ meson properties in an arbitrary magnetic field
Taking an effective ρππ interaction, the self energy of ρ at finite temperature in an arbitrary external magnetic field is calculated using the real time formalism of thermal field theory. The effect of temperature and magnetic field on the in-medium spectral functions are studied. The effective mass and dispersion relations are evaluated from the pole of the complete ρ propagator. We find sign...

Integral and derivative dispersion relations in the analysis of the data on pp and ¯ pp forward scattering. Abstract Integral and derivative dispersion relations (DR) are considered for the pp and ¯ pp forward scattering amplitudes. A new representation for the derivative DR, valid at lower energies than the standard one, is obtained. The data on the total cross sections of pp(¯ pp) interaction...
متن کاملA Robust Dispersion Control Chart Based on M-estimate
Process control charts are proven techniques for improving quality. Specifying the control limits is the most important step in designing a control chart. The presence of outliers may extremely affect the estimates of parameters using classical methods. Robust estimators which are not affected by outliers or the small departures from the model assumptions are applied in this paper to specify th...
