Metastable cosmic strings / Buchmuller, Wilfried (DESY) ; Domcke, Valerie (CERN) ; Schmitz, Kai (Munster U.)
Many symmetry breaking patterns in grand unified theories (GUTs) give rise to cosmic strings that eventually decay when pairs of GUT monopoles spontaneously nucleate along the string cores. These strings are known as metastable cosmic strings and have intriguing implications for particle physics and cosmology. [...]

Stochastic gravitational-wave background from metastable cosmic strings / Buchmuller, Wilfried (DESY) ; Domcke, Valerie (CERN ; Ecole Polytechnique, Lausanne) ; Schmitz, Kai (CERN)
A metastable cosmic-string network is a generic consequence of many grand unified theories (GUTs) when combined with cosmic inflation. Metastable cosmic strings are not topologically stable, but decay on cosmic time scales due to pair production of GUT monopoles. [...]

From NANOGrav to LIGO with metastable cosmic strings / Buchmuller, Wilfried (DESY) ; Domcke, Valerie (CERN ; EPFL, Lausanne, LPPC) ; Schmitz, Kai (CERN)
We interpret the recent NANOGrav results in terms of a stochastic gravitational wave background from metastable cosmic strings. The observed amplitude of a stochastic signal can be translated into a range for the cosmic string tension and the mass of magnetic monopoles arising in theories of grand unification. [...]

Probing the scale of grand unification with gravitational waves / Buchmuller, Wilfried (DESY) ; Domcke, Valerie (DESY) ; Murayama, Hitoshi (DESY ; UC, Berkeley ; LBL, Berkeley ; Tokyo U., IPMU) ; Schmitz, Kai (CERN)
The spontaneous breaking of U(1)_B-L around the scale of grand unification can simultaneously account for hybrid inflation, leptogenesis, and neutralino dark matter, thus resolving three major puzzles of particle physics and cosmology in a single predictive framework. The B-L phase transition also results in a network of cosmic strings. [...]

Large-Field Inflation and Supersymmetry Breaking / Buchmuller, Wilfried (CERN) ; Dudas, Emilian (DESY ; Ecole Polytechnique, CPHT) ; Heurtier, Lucien (Ecole Polytechnique, CPHT ; DESY) ; Wieck, Clemens (DESY)
Large-field inflation is an interesting and predictive scenario. Its non-trivial embedding in supergravity was intensively studied in the recent literature, whereas its interplay with supersymmetry breaking has been less thoroughly investigated. [...]

A Minimal Supersymmetric Model of Particle Physics and the Early Universe / Buchmüller, W (DESY) ; Domcke, V (DESY) ; Kamada, K (DESY) ; Schmitz, K (Tokyo U., IPMU)
We consider a minimal supersymmetric extension of the Standard Model, with right-handed neutrinos and local $B$$-$$L$, the difference between baryon and lepton number, a symmetry which is spontaneously broken at the scale of grand unification. To a large extent, the parameters of the model are determined by gauge and Yukawa couplings of quarks and leptons. [...]

Seesaw Neutrinos from the Heterotic String / Buchmuller, Wilfried (DESY) ; Hamaguchi, Koichi (Tokyo U.) ; Lebedev, Oleg (CERN) ; Ramos-Sanchez, Saul (Bonn U.) ; Ratz, Michael (Munich, Tech. U.)
We study the possibility of realizing the neutrino seesaw mechanism in the E8XE8 heterotic string. In particular, we consider its Z_6 orbifold compactifications leading to the supersymmetric standard model gauge group and matter content. [...]

Physics Interplay of the LHC and the ILC / Weiglein, G. (Durham U., IPPP) ; Barklow, T. ; Boos, E. ; De Roeck, A. ; Desch, K. ; Gianotti, F. ; Godbole, R. ; Gunion, J.F. ; Haber, H.E. ; Heinemeyer, S. et al. /LHC-ILC Study Group
Physics at the Large Hadron Collider (LHC) and the International e+e- Linear Collider (ILC) will be complementary in many respects, as has been demonstrated at previous generations of hadron and lepton colliders. This report addresses the possible interplay between the LHC and ILC in testing the Standard Model and in discovering and determining the origin of new physics. [...]
