Low - energy dynamics in N = 2 super QED : Two - loop approximation
The two-loop (Euler-Heisenberg-type) effective action for N = 2 supersymmetric QED is computed using the N = 1 superspace formulation. The effective action is expressed as a series in supersymmetric extensions of F 2n, where n = 2, 3, . . ., with F the field strength. The corresponding coefficients are given by triple propertime integrals which are evaluated exactly. As a by-product, we demonst...
متن کاملTwo-loop QED with External Magnetic Field
In two loop effective Lagrangian, the low temperature expansion of the QED3+1 with a constant magnetic field and a finite chemical potential is performed. We then calculate the total fermion density, some components of polarization operator and de Hass -van Alphen oscillations. We find that there is a significant contribution from two-loop expansion to magnetization and fermion density for high...
متن کاملTwo-Loop Bhabha Scattering in QED
In the context of pure QED, we obtain analytic expressions for the contributions to the Bhabha scattering differential cross section at order α4 which originate from the interference of two-loop photonic vertices with tree-level diagrams and from the interference of one-loop photonic diagrams amongst themselves. The ultraviolet renormalization is carried out. The IR-divergent soft-photon emissi...
متن کاملTwo-loop QED Corrections to Bhabha Scattering
Bhabha scattering, ee → ee, is a crucial process in the phenomenology of particle physics. Its relevance is mainly due to the fact that it is the process employed to determine the luminosity L at ee colliders: in fact, L = NBhabha/σth, where NBhabha is the rate of Bhabha events and σth is the Bhabha scattering cross section calculated from theory. Two kinematic regions are of special interest f...
متن کاملTwo-Loop Form Factors in QED
We evaluate the on shell form factors of the electron for arbitrary momentum transfer and finite electron mass, at two loops in QED, by integrating the corresponding dispersion relations, which involve the imaginary parts known since a long time. The infrared divergences are parameterized in terms of a fictitious small photon mass. The result is expressed in terms of Harmonic Polylogarithms of ...
