GKZ hypergeometric systems of the three-loop vacuum Feynman integrals
Hai-Bin Zhang, Tai-Fu Feng
We present the Gel'fand-Kapranov-Zelevinsky (GKZ) hypergeometric systems of the Feynman integrals of the three-loop vacuum diagrams with arbitrary masses, basing on Mellin-Barnes r…

Vacuum instability in a constant inhomogeneous electric field. A new example of exact nonperturbative calculations
T. C. Adorno, S. P. Gavrilov, D. M. Gitman
Basic quantum processes (such as particle creation, reflection, and transmission on the corresponding Klein steps) caused by inverse-square electric fields are calculated. These re…

GKZ-hypergeometric systems for Feynman integrals
Tai-Fu Feng, Chao-Hsi Chang, Jian-Bin Chen +1
Basing on the systems of linear partial differential equations derived from Mellin-Barnes representations and Miller's transformation, we obtain GKZ-hypergeometric systems of one-l…
