71. Hidden Conformal Symmetry of Maxwell's Theory in $d\neq 4$

Ms Kelly Chiu (SLAC)

Oral contribution

In this work, we define a modified non-local conformal transformation compatible with BRST formalism for $U(1)$ gauge field, which is a symmetry of the Maxwell's theory in any dimension. We prove the invariance by explicitly showing that the gauge invariant transverse two point function, the classical action, and equation of motion are unchanged under such transfomation.

42. Light-Front Quantization of the Vector Schwinger Model \\ with a Photon Mass Term in Faddeevian Regularization

Oral contribution

In this talk, we study the light-front quantization of the vector Schwinger model with photon mass term in Faddeevian Regularization, describing two-dimensional electrodynamics with mass-less fermions but with a mass term for the $ U(1)$ gauge field \cite{13}-\cite{15}. This theory is seen to be gauge-non-invariant (GNI). We then construct a gauge-invariant (GI) theory corresponding to this...

25. Light-front $\phi^4_{1+1}$ theory using a many-boson symmetric-polynomial basis.

Sophia Chabysheva (University of Minnesota-Duluth)

Oral contribution

We extend earlier work on fully symmetric polynomials for three-boson wave functions to arbitrarily many bosons and apply these to a light-front analysis of the low-mass eigenstates of $\phi^4$ theory in 1+1 dimensions. The basis-function approach allows the resolution in each Fock sector to be independently optimized, which can be more efficient than the preset discrete Fock states in DLCQ. ...

2. True muonium on the light front

Mr Henry Lamm (Arizona State University)

Oral contribution

The true muonium (μ^+μ^-) bound state presents an interesting test of light-cone quantization techniques. In addition to the standard problems of solving these non-perturbative calculations, true muonium requires correct treatment of e^+e^- Fock state contributions. Having previously produced a crude model of true muonium using the method of iterated resolvents [1], current work has focused...
