Gauge Principle and Qed *

نویسنده

  • Norbert Straumann
چکیده

One of the major developments of twentieth century physics has been the gradual recognition that a common feature of the known fundamental interactions is their gauge structure. In this talk the early history of gauge theory is reviewed, emphasizing especially Weyl’s seminal contributions of 1918 and 1929.

نظریه میدان ناجابه‌جایی و پارامترهای نقض لورنتس در QED

Non-commutative field theory as a theory including the Lorentz violation can be constructed in two different ways. In the first method, the non-commutative fields are the same as the ordinary ones while the gauge group is restricted to U(n). For example, the symmetry group of standard model in non-commutative space is U(3)×(2)×U(1) which can be reduced to SU(3)×SU(2)×U(1) by two appropriate spo...

The three-loop free energy for high-temperature QED and QCD with fermions

We compute the free energy density for gauge theories, with fermions, at high temperature and zero chemical potential. Specifically, we analytically compute the free energy through O(g4), which requires the evaluation of threeloop diagrams. This computation extends our previous result for pure gauge QCD.

Three point SUSY Ward identities without Ghosts

We utilise a non-local gauge transform which renders the entire action of SUSY QED invariant and respects the SUSY algebra modulo the gauge-fixing condition, to derive twoand three-point ghost-free SUSY Ward identities in SUSY QED. We use the cluster decomposition principle to find the Green’s function Ward identities and then takes linear combinations of the latter to derive identities for the...

Extended BRS Symmetry and Gauge Independence in On-Shell Renormalization Schemes

Extended BRS symmetry is used to prove gauge independence of the fermion renormalization constant Z2 in on-shell QED renormalization schemes. A necessary condition for gauge independence of Z2 in on-shell QCD renormalization schemes is formulated. Satisfying this necessary condition appears to be problematic at the three-loop level in QCD. In on-shell schemes, the fermion mass renormalization Z...
