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…
Superpotential de-sequestering in string models
Marcus Berg, Joseph P. Conlon, David Marsh +1
Non-perturbative superpotential cross-couplings between visible sector matter and Kähler moduli can lead to significant flavour-changing neutral currents in compactifications of ty…
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…
