Factorization in extended electroweak gauge models
Physical Review D, 1981Extensions of the standard electroweak ${G}^{0}\ensuremath{\equiv}\mathrm{SU}{(2)}_{L}\ifmmode\times\else\texttimes\fi{}\mathrm{U}(1)$ gauge model, which include more neutral vector bosons, are strongly restricted but not excluded by the Hung-Sakurai (HS) factorization relations on neutrino-quark, neutrino-electron, and electron-quark amplitudes.

Behaviour of electrical resistance strain gauges at low temperatures II. Gauge factor
Cryogenics, 1967The authors continue their report of an investigation of the characteristics of strain gauges in the range 0—300° K from the previous paper with a study of ‘gauge factor’ G. Some results are given and the physical origin G is discussed.

Method for rapid determination of ion gauge sensitivity factors
Review of Scientific Instruments, 2007In ultrahigh vacuum thin film growth processes using gas phase growth precursors, the pressure of the gas at or near the substrate is a critical parameter since it is directly related to the collision frequency of the precursor with the substrate and ultimately to the growth rate.

Physical Review D, 1985
We prove Ward-type identities which are needed in the proof of factorization of the Drell-Yan process. Previous treatments prove them only for an axial gauge, and the proofs are diagrammatic in nature. We, on the other hand, establish the identities for the Feynman gauge and through symmetry considerations at the Lagrangian level.

Temperature dependence of gauge factor and magnetoresistance of some platinum-tungsten strain gauges
Journal of Physics E: Scientific Instruments, 1972The gauge factor of some Denfoil type 1831 NE foil gauges was found to increase monotonically by 5.7% of its room temperature value of 4.45 as the temperature was lowered to 4K. The magnetoresistance is negligible at room temperature and even at 4K and 1T is only equivalent to a strain of about 1.6*10-6, with an anisotropic part of about 0.5*10-6.

Gas Correction Factors for Vacuum Pressure Gauges
Vakuum in Forschung und Praxis, 2017AbstractVacuum pressure gauges will typically arrive from a manufacturer calibrated for nitrogen; for other gases, to avoid potentially significant measurement errors, a correction factor must be used to convert ‘measured’ or ‘indicated’ pressure to ‘true’ pressure.

WEYL'S GAUGE TRANSFORM AND QUANTUM GEOMETRIC PHASE FACTORS
Modern Physics Letters A, 2007The historical and geometrical origin of Gauge Transformation and Yang's phase loop of gauge theory are discussed. In the present talk, we present the following points: 1. Parallel transport of a vector; 2. Weyl 1918 gauge transformation 3. Concept of non-integrable phase factor; 4. Berry's quantum geometrical phase; 5.

Chern-Simons induced spin factors in noncovariant gauges
Physical Review D, 1993We study Chern-Simons induced spin factors in noncovariant metric-independent gauges, such as the axial gauge and the Coulomb gauge. These spin factors are defined without loop splitting. We find that they are equal to integers and have particular geometrical meanings.

Forms of Gauge Fields and Nonintegrable Phase Factors
Physical Review Letters, 1976I show the connection between the magnetic monopoles with quantized strength and the form of solutions of gauge fields. A generalized electromagnetic field tensor f/sub mu//sub nu/ and its physical implications in a unified gauge theory are discussed. (AIP)
