Within the superfield approach, we discuss three-dimensional supersymmetric (SUSY) pseudo-QED. We prove that it is all-loop renormalizable. demonstrate SUSY pseudo-QED action can be generated as a quantum correction from coupling of spinor gauge to set $N$ massless complex scalar superfields. Afterwards, calculate two-point function superfields in which displays divergence vanishing certain gau...

We consider resonances in the Pauli-Fierz model of non-relativistic QED. We use and slightly modify the analysis developed by Bach, Fröhlich and Sigal [3, 4] to obtain an upper and lower bound on the lifetime of quasi-stationary states.

Auger dominant metastable states in the antiprotonic helium atoms are studied by using the Complex Coordinate Rotation method. Relativistic corrections for the bound electron related to the Breit interaction have been calculated using CCR wave functions. Higher order relativistic and QED effects have been included into consideration to get precise theoretical values for transition frequencies.

For the study of deep inelastic scattering at HERA, the use of Jaquet-Blondel variables is advantageous in several respects. We calculate the complete leptonic O(α) QED corrections for the reaction ep → eX in these variables. All but one phase space integrations are performed analytically. After exponentiation of soft photon corrections, an accuracy of at least 1% is matched. Numerical results ...

Proof: As in [Z], first use the Stembridge-Stanton trick, to transform (*) to the equivalent ”antisymmetric” version, let’s call it (*’), in which ( qxj xi )a is replaced by ( qxj xi ) a−1 , and the right side of (*) gets multiplied by (1− t)/(t; t)a. Next expand the very first product on the left of (*’), into a sum of 2 terms, and note that they are all bad guys (see [Z], p. 314 ), except for...

We present the first completely analytical computationof the full differentialγ-γ pair production rate fromcompact radiation fields, exact to 2nd order QED, and use this result to investigate the validity of previously known approximations.

In 1994 the QED Manifesto described an ideal whereby mathematics is communicated via a computerized system in a fully formalized fashion complete with automatic proof checking and other derived tools facilitating profound improvements to the way mathematics is taught, the way new results are disseminated, and ultimately to how mathematics is practiced. Two decades later it is safe to say the dr...

The reaction e + e ? ! is an ideal process to test QED in e + e ? collisions, since it does not receive tree level contribution from the exchange of weak bosons. It can thus be used to set limits on the energy scale of new interactions. In this note we review two technical aspects related to the study of the e + e ? ! reaction: the deenition of the scattering angle, which is aaected by the pres...
