Constraining the real singlet extension of the Standard Model: implications for vacuum stability

Moritz Bosse, Gudrun Hiller, Daniel Litim +4

The paper investigates the addition of a real singlet scalar to the Standard Model, analyzing theoretical and experimental constraints and its impact on electroweak phase transitio…

Spectral Functions of Lorentzian Quantum Gravity

Gabriel Assant, Daniel F. Litim, Manuel Reichert

We compute spectral functions of graviton modes in Lorentzian quantum gravity, interpolating between classical general relativity and an asymptotically safe ultraviolet fixed point…

Constraining the real scalar singlet extension of the SM

Moritz Bosse, Gudrun Hiller, Daniel Litim +4

The real scalar singlet extension of the standard model provides a minimal framework in which the Higgs sector can realise a strong first-order electroweak phase transition and imp…

Four Fermi Theory in Four Dimensions is Renormalisable

Charlie Cresswell-Hogg, Daniel F. Litim

We demonstrate the renormalisability of quantum field theories in four dimensions with elementary self-interacting Dirac fermions and to leading order in the limit of many fermion…

Vacuum Stability in the Standard Model and Beyond

Gudrun Hiller, Tim Höhne, Daniel F. Litim +1

We revisit the stability of the Standard Model vacuum, and investigate its quantum effective potential using the highest available orders in perturbation theory and the most accura…

Fixed points of semi-simple supersymmetric gauge theories

Andrew D. Bond, Daniel F. Litim, Gabriel Picanço

We study fixed points and phase diagrams of semi-simple supersymmetric gauge theories coupled to chiral superfields and a superpotential. Particular emphasis is put on new phenomen…
