String-motivated one-loop amplitudes in gauge theories with half-maximal supersymmetry
Marcus Berg, Igor Buchberger, Oliver Schlotterer
We compute one-loop amplitudes in six-dimensional Yang-Mills theory with half-maximal supersymmetry from first principles: imposing gauge invariance and locality on an ansatz made…
From maximal to minimal supersymmetry in string loop amplitudes
Marcus Berg, Igor Buchberger, Oliver Schlotterer
We calculate one-loop string amplitudes of open and closed strings with N=1,2,4 supersymmetry in four and six dimensions, by compactification on Calabi-Yau and K3 orbifolds. In par…
On the Killing form of Lie Algebras in Symmetric Ribbon Categories
Igor Buchberger, Jürgen Fuchs
As a step towards the structure theory of Lie algebras in symmetric monoidal categories we establish results involving the Killing form. The proper categorical setting for discussi…
Higgs diphoton rate enhancement from supersymmetric physics beyond the MSSM
Marcus Berg, Igor Buchberger, D. M. Ghilencea +1
We show that supersymmetric "new physics" beyond the MSSM can naturally accommodate a Higgs mass near 126 GeV and enhance the signal rate in the Higgs to diphoton channel, while th…
Growth Histories in Bimetric Massive Gravity
Marcus Berg, Igor Buchberger, Jonas Enander +2
We perform cosmological perturbation theory in Hassan-Rosen bimetric gravity for general homogeneous and isotropic backgrounds. In the de Sitter approximation, we obtain decoupled…
