Nucleon Compton scattering in the Dyson-Schwinger approach
Gernot Eichmann, Christian S. Fischer
We analyze the nucleon's Compton scattering amplitude in the Dyson-Schwinger/Faddeev approach. We calculate a subset of diagrams that implements the nonperturbative handbag contrib…
Variations of magnetic bright point properties with longitude and latitude as observed by Hinode/SOT G-band data
D. Utz, A. Hanslmeier, A. Veronig +4
Small-scale magnetic fields can be observed on the Sun in high resolution G-band filtergrams as magnetic bright points (MBPs). We study Hinode/ Solar Optical Telescope (SOT) longit…
On the analytic structure of scalar glueball operators at Born level
Andreas Windisch, Markus Q. Huber, Reinhard Alkofer
We study the analytic structure of the two-point function of the operator F2 which is expected to describe a scalar glueball. The calculation of the involved integrals is complicat…
Variational solution of congruent transformed Hamiltonian for many-electron systems using full configuration interaction calculation
Jennifer M. Elward, Johannes Hoja, Arindam Chakraborty
The congruent transformation of the electronic Hamiltonian is developed to address the electron correlation problem in many-electron systems. The central strategy presented in this…
Signatures of magnetic reconnection in solar eruptive flares: A multi-wavelength perspective
Bhuwan Joshi, Astrid Veronig, P. K. Manoharan +1
In this article, we review some key aspects of a multi-wavelength flare which have essentially contributed to form a standard flare model based on the magnetic reconnection. The em…
The Large Davenport Constant II: General Upper Bounds
D. J. Grynkiewicz
Let be a finite group written multiplicatively. By a sequence over , we mean a finite sequence of terms from which is unordered, repetition of terms allowed, and we say…
