Two-Loop Euler-Heisenberg QED Pair-Production Rate
We study the divergence of large-order perturbation theory in the worldline expression for the two-loop Euler-Heisenberg QED eeective Lagrangian in a constant magnetic eld. The leading rate of divergence is identical, up to an overall factor, to that of the one-loop case. From this we deduce, using Borel summation techniques, that the leading behaviour of the imaginary part of the two-loop eeec...
متن کاملTwo-loop Corrections to Fermion Pair Production Vertices†
Recent results on the entirely analytic calculation of second order corrections to massive quark pair production vertices induced by light quark flavours are reviewed. Based on the method presented in this talk the second order effects of the insertion of any massless one-loop vacuum polarization into the gluon line of the first order diagrams can be determined. The behaviour of the corrections...
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...
