A Bibliography on the Applications of Mathematical Programming Multiple-objective Methods

This paper gives a bibliography on applications of multiple-objective methods which use no a priori explicit value function and are complex enough to require mathematical programming aids. A commentary on the applications and on the survey is also given which may be helpful for further work of this kind. The survey covers the period 1955-86.     

Nucleon structure functions from high energy neutrino interactions

Structure functions obtained from high energy neutrino and antineutrino scattering from an iron target are presented. These were extracted from the combined data of Fermilab experiments E616 and E701; these utilized narrow band beam runs between 1979–1982. The structure functions are used to test the validity of quarkparton model (QPM) predictions and to extract the QCD scale parameter Λ from fits to the Altarelli-Parisi equations.     

Mode beating in spot-size converter lasers

An anomalous modulation in the wavelength spectrum has been observed in lasers with spot-size converters. This intensity modulation is shown to be caused by beating between the fundamental lasing mode and radiation modes in the taper. This results in a periodic modulation in the net gain spectrum, which causes wavelength jumps between adjacent net gain maxima, and a drive current dependent spectral width that is expected to affect system performance. The amplitude of this spectral modulation is reduced significantly by either using an angled rear-facet which reflects the beating radiation modes away from the laser axis, or by using a nonlinear, adiabatic taper.     

Kaon production in\bar pp interactions at c.m. energies from 200 to 900 GeV

A detailed analysis ofK _s ⁰ production in \(\bar pp\) |<2.5 the average transverse momentum is found to be 0.53±0.07 GeV/c at 200 GeV and 0.62±0.08 GeV/c at 900 GeV, which is an increase with respect to data at c.m. energies below 60 GeV. TheK _s ⁰ production cross sections in inelastic collisions are 29±4 mb at 200 GeV and 63±6 mb at 900 GeV, showing an increase compared to lower energy data. The central kaon density is found to increase as a logarithmic function of energy. At 900 GeV, where statistics are sufficient to allow one to draw conclusions, the average transverse momentum is higher in events with large charged multiplicity than in events with low multiplicity.     

Calculation of the strong coupling, αs,from considerations of virtual synchrotron radiation resulting in hadron pair emission

Based upon a recently published work in which a model for hadron pair production via virtual synchrotron radiation in uniform magnetic fields was introduced, an ansatz for calculating _s is presented. The resulting function is unique within the above-mentioned context. Along with a scheme introduced in which vector mesons arise by virtue of quark spin-flip with accompanying gluon emission, the _s function is used to successfully explain the observed hadronic widths of the ,, andJ mesons. In addition the hadronic and leptonic widths of the upsilon meson are calculated. Based upon gathered upsilon data, a charge on theb quark of (2e/3) is found to be consistent with the above model. Finally, the derived _s function is compared with results of gauge-theoretical calculations.
