Gravitational waves from conformal symmetry breaking
Tomislav Prokopec, Jonas Rezacek, Bogumila Swiezewska
We consider the electroweak phase transition in the conformal extension of the standard model known as SU(2)cSM. Apart from the standard model particles, this model contains an add…
Systematic analysis of radiative symmetry breaking in models with extended scalar sector
Leonardo Chataignier, Tomislav Prokopec, Michael G. Schmidt +1
Radiative symmetry breaking (RSB) is a theoretically appealing framework for the generation of mass scales through quantum effects. It can be successfully implemented in models wit…
Conformal symmetry and the cosmological constant problem
Stefano Lucat, Tomislav Prokopec, Bogumila Swiezewska
We argue that, when a theory of gravity and matter is endowed with (classical) conformal symmetry, the fine tuning required to obtain the cosmological constant at its observed valu…
Single-scale Renormalisation Group Improvement of Multi-scale Effective Potentials
Leonardo Chataignier, Tomislav Prokopec, Michael G. Schmidt +1
We present a new method for renormalisation group improvement of the effective potential of a quantum field theory with an arbitrary number of scalar fields. The method amounts to…
