We outline the necessary computational details, ultraviolet renormalization and corresponding universal infrared structure..

Scalar one-loop vertex integrals as meromorphic functions of space-time dimension d [KW 17-002, DESY 17-186, DO-TH 17/29] XLI International Conference of Theoretical Physics “Matter to the Deepest”, , Meeting locationPodlesice, Poland, 3 Sep 2017 - 8 Sep 2017 Acta physica Polonica / B / Proceedings supplement 48(12), 2313-2320 (2017) [10.5506/APhysPolB.48.2313]   Representations are derived for the basic scalar one-loop vertex Feynman integrals as meromorphic functions of the space-time dimension $d$ in terms of (generalized) hypergeometric functions $_2F_1$ and $F_1$. Values at asymptotic or exceptional kinematic points as well as expansions around the singular points at $d=4+2n$, $n$ non-negative integers, may be derived from the representations easily.

Threshold and Jet Radius Joint Resummation for Single-Inclusive Jet Production Physical review letters 119(21), 212001 (2017) [10.1103/PhysRevLett.119.212001] 2018-01-1513:45 [PUBDB-2018-00647] Journal Article et al THz pulse doubler at FLASH: double pulses for pump–probe experiments at X-ray FELs Photondiag 2017, , Journal of synchrotron radiation 25, 39-43 (2018) [10.1107/S1600577517015442] special issue: "Photondiag2017 workshop"   FLASH, the X-ray free-electron laser in Hamburg, Germany, employs a narrowband high-field accelerator THz source for unique THz pump X-ray probe experiments. However, the large difference in optical paths of the THz and X-ray beamlines prevents utilization of the machine’s full potential (e.g. [...] Restricted: PDF PDF (PDFA); 2018-01-1415:47 [PUBDB-2018-00634] Journal Article Brezesinski, T. Synthesis, structural characterization and magnetic properties of ordered mesoporous $Pr_{1−x}Ca_{x}MnO_{3}$ thin films CrystEngComm 20(2), 245 - 250 (2018) [10.1039/C7CE01946G]   Mixed-valence manganese oxides with a perovskite structure are promising candidates for next-generation electronic devices, among others, because of the combination of ferromagnetism with other technologically important properties. Herein we report the block copolymer-templating synthesis, structural characterization and magnetic properties of thermally stable thin films of cubic mesoporous praseodymium calcium manganite (PCMO), Pr1−xCaxMnO3 with x ≈ 0.3.

The intrapulse difference-frequency generation (DFG) pumped by a broadband pulse is a reliable method of producing passively CEP-stable pulses.
