Observability Of The Anapole Moment And Neutrino Charge Radius, Mj Musolf, Br Holstein Apr 1991

Observability Of The Anapole Moment And Neutrino Charge Radius, Mj Musolf, Br Holstein

Barry R Holstein

The properties of the neutrino charge radius (NCR) and anapole moments (AM's) of elementary fermions, nucleons, and nuclei are discussed. The dependence of these off-shell electromagnetic couplings on the weak gauge parameter is explicitly demonstrated by a calculation performed in the Rξ gauge. The gauge dependence of the AM's and NCR implies that they cannot be observed in isolation from other second-order, electroweak effects. It is shown, however, that the AM's of various hadronic systems having an SU(2)L quantum number TL3=0 can be considered ``observables'' in certain formal, though unphysical, limits. It is argued that, apart from these special limits, …

Foundations Of Fuzzy Sets, Lawrence Stout, Ulrich Höhle Dec 1990

Foundations Of Fuzzy Sets, Lawrence Stout, Ulrich Höhle

Lawrence N. Stout

This paper gives an overview of the origins of fuzzy set theory and the problems for the foundations of fuzzy sets arising from those origins and current practice. It then gives detailed accounts of categorical approaches using a closed structure to capture the fuzzy AND connective. Within these categories weak forms of subobject representations provide an internal second order logic. An approach to fuzzy real numbers and fuzzy topology is included to illustrate the use of this internal; second order theory.

A Survey Of Fuzzy Set And Topos Theory, Lawrence Stout Dec 1990

A Survey Of Fuzzy Set And Topos Theory, Lawrence Stout

Lawrence N. Stout

This paper is a comparison and contrast of approaches to many-valued mathematics offered by Fuzzy Set theory and topos theory. It gives a survey of the categorical foundations of Fuzzy Set theory and related topoi. Topoi are not a basis for Fuzzy Set theory but they do suggest appropriate directions to go and questions to ask for a synthesis which does provide a foundation. One possible structure which has a topos-like internal logic and the, rich variety of logical connectives used in fuzzy sets is included.


Higgs-Boson Production In Peripheral Heavy-Ion Collisions: Electromagnetic Production, Alec Schramm, Burndt Muller Nov 1990

Higgs-Boson Production In Peripheral Heavy-Ion Collisions: Electromagnetic Production, Alec Schramm, Burndt Muller

Alec J Schramm

Higgs-boson production via fusion of two virtual photons in nuclear collisions at energies of several TeV per nucleon is calculated. It is shown that although a trigger on quasielastic nuclear collisions suppresses the Higgs-boson production cross section, this mechanism could still provide a method for producing and detecting intermediate-mass Higgs bosons (MZ≲MH≲2MW).

The Zero Momentum Limit Of The Vacuum Polarization At Finite Temperature, Ps Gribosky, Br Holstein Dec 1989

The Zero Momentum Limit Of The Vacuum Polarization At Finite Temperature, Ps Gribosky, Br Holstein

Barry R Holstein

We examine the zero momentum limit of the finite temperature vacuum polarization for a quantized scalar field coupled to a classical external field. Ordinarily, this type of Feynman diagram is plagued by nonanalytic behaviour when the external momentum tends to zero. Using imaginary-time, we show that this behaviour is not present in an exact background field solution and how the Feynman diagram calculation may be trivially modified to match the exact solution. Comparisons with recent real-time results are also made.

Kaon Transitions And Predictions Of Chiral Symmetry, Jf Donoghue, Br Holstein Nov 1989

Kaon Transitions And Predictions Of Chiral Symmetry, Jf Donoghue, Br Holstein

Barry R Holstein

We describe a set of kaonic electromagnetic and semileptonic weak decay processes which are completely predicted within the framework of chiral symmetry (and, therefore, of low-energy QCD), emphasizing where present problems exist and suggesting future experiments.

The Adiabatic Propagator, Br Holstein Dec 1988

The Adiabatic Propagator, Br Holstein

Barry R Holstein

The Feynman propagator is expanded in the adiabatic limit, wherein the time scale over which the potential varies is long compared to typical quantum mechanical oscillation times in the problem. Comparison with known exact results is made for two simple models.
