Closed-form weak-field expansion of two-loop Euler-Heisenberg Lagrangians
We obtain closed-form expressions, in terms of the Faulhaber numbers, for the weak-field expansion coefficients of the two-loop Euler-Heisenberg effective Lagrangians in a magnetic or electric field. This follows from the observation that the magnetic worldline Green’s function has a natural expansion in terms of the Faulhaber numbers.
متن کاملTwo-loop self-dual Euler-Heisenberg Lagrangians (II): Imaginary part and Borel analysis
We analyze the structure of the imaginary part of the two-loop Euler-Heisenberg QED effective Lagrangian for a constant self-dual background. The novel feature of the two-loop result, compared to one-loop, is that the prefactor of each exponential (instanton) term in the imaginary part has itself an asymptotic expansion. We also perform a high-precision test of Borel summation techniques applie...
متن کاملTwo-loop self-dual Euler-Heisenberg Lagrangians (I): Real part and helicity amplitudes
We show that, for both scalar and spinor QED, the two-loop Euler-Heisenberg effective Lagrangian for a constant Euclidean self-dual background has an extremely simple closed-form expression in terms of the digamma function. Moreover, the scalar and spinor QED effective Lagrangians are very similar to one another. These results are dramatic simplifications compared to the results for other backg...

We clarify a discrepancy between two previous calculations of the two-loop QED Euler-Heisenberg Lagrangian, both performed in proper-time regularization, by calculating this quantity in dimensional regularization. e-mail address D.FliegnerThPhys.Uni-Heidelberg.De e-mail address M.G.SchmidtThPhys.Uni-Heidelberg.De e-mail address [email protected] Supported by Deutsche Forschungsg...
متن کاملTwo-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...
