Metastable cosmic strings
Wilfried Buchmuller, Valerie Domcke, Kai Schmitz
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 stri…
The cosmological constant as a boundary term
Wilfried Buchmuller, Norbert Dragon
We compare the path integral for transition functions in unimodular gravity and in general relativity. In unimodular gravity the cosmological constant is a property of states that…
Stochastic gravitational-wave background from metastable cosmic strings
Wilfried Buchmuller, Valerie Domcke, Kai Schmitz
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 topological…
Baryogenesis from the weak scale to the grand unification scale
Dietrich Bodeker, Wilfried Buchmuller
We review the current status of baryogenesis with emphasis on electroweak baryogenesis and leptogenesis. The first detailed studies were carried out for SU(5) GUT models where CP-v…
Vacuum stability and supersymmetry at high scales with two Higgs doublets
Emanuele Bagnaschi, Felix Brümmer, Wilfried Buchmüller +2
We investigate the stability of the electroweak vacuum for two-Higgs doublet models with a supersymmetric UV completion. The supersymmetry breaking scale is taken to be of the orde…
Large-Field Inflation and Supersymmetry Breaking
Wilfried Buchmuller, Emilian Dudas, Lucien Heurtier +1
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 w…
