The Pinch Technique Beyond One Loop: The Gauge-Independent Two-Loop Quark Self-Energy
It is shown how the pinch technique algorithm may be consistently extended beyond the one-loop level to obtain the gauge-independent two-loop fermion self-energy −iΣ̂(p) in QCD in the pinch technique approach. The starting point for the construction is the general diagrammatic representation of the two-loop quark self-energy in terms of renormalized one-loop twoand three-point function and tree ...
متن کاملGauge-independent Thermal β Function in Yang-Mills Theory via the Pinch Technique
It is proposed to use the pinch technique to obtain the gauge-independent thermal β function βT in a hot Yang-Mills gas. Calculations of βT are performed at one-loop level in four different gauges, (i) the background field method with an arbitrary gauge parameter, (ii) the Feynman gauge, (iii) the Coulomb gauge, and (iv) the temporal axial gauge. When the pinch contributions to the gluon self-e...
متن کاملQUANTALE-VALUED GAUGE SPACES
We introduce a quantale-valued generalization of approach spaces in terms of quantale-valued gauges. The resulting category is shown to be topological and to possess an initially dense object. Moreover we show that the category of quantale-valued approach spaces defined recently in terms of quantale-valued closures is a coreflective subcategory of our category and, for certain choices of the qu...
متن کاملReliability of the Pinch Strength with Digitalized Pinch Dynamometer
OBJECTIVE To examine the intra-rater, inter-rater, and inter-instrumental reliability of the digitalized pinch muscle strength dynamometer. METHOD Thirty normal subjects were examined for pinch strength, using both the Preston pinch gauge and the digitalized pinch dynamometer. The participants performed all pinch strength tests in the seated position as recommended by the American Society of ...
متن کاملScam Feels the Pinch
The paper by Movileanu et al. (2001) in this issue of The Journal describes a test of the applicability of the substituted-cysteine-accessibility method (SCAM; Akabas et al., 1992; Akabas et al., 1994) to the problem of locating the narrowest region of a channel lumen. Movileanu et al. (2001) use unusually large sulfhydryldirected reagents to probe the wide bore channel formed by Staphylococcal...
