Meson spectra of asymptotically free gauge theories from holography
Johanna Erdmenger, Nick Evans, Marc Scott
Using holography, we study the low-lying mesonic spectrum of a range of asymptotically free gauge theories. First we revisit a simple top-down holographic model of QCD-like dynamic…
GoSam 2.0: Automated one loop calculations within and beyond the Standard Model
Nicolas Greiner
We present GoSam 2.0, a fully automated framework for the generation and evaluation of one loop amplitudes in multi leg processes. The new version offers numerous improvements both…
Considerations concerning the generalization of the Dirac equations to unstable fermions
Bernd A. Kniehl, Alberto Sirlin
We discuss the generalization of the Dirac equations and spinors in momentum space to free unstable spin- fermions taking into account the fundamental requirement of Lorentz c…
Radiative decay of keV-mass sterile neutrinos in a strongly magnetized plasma
Alexandra A. Dobrynina, Nicolay V. Mikheev, Georg G. Raffelt
The radiative decay of sterile neutrinos with typical masses of 10 keV is investigated in the presence of a strong magnetic field and degenerate plasma. Full account is taken of th…
