The hierarchy problem and fine-tuning in a decoupling approach to multi-scale effective potentials
Simone Biondini, Daniël Boer, Ruud Peeters
In many realizations of beyond the Standard Model theories, new massive particles are introduced, leading to a multi-scale system with widely separated energy scales. In this setti…

Fine-tuning and the doublet-triplet splitting problem in the minimal GUT
Daniël Boer, Ruud Peeters
In this paper we analyse the doublet-triplet splitting problem in the minimal non-super-symmetric GUT. We take into account the full symmetry breaking pattern with both hig…

Analysis of fine-tuning measures in models with extended Higgs sectors
Daniël Boer, Ruud Peeters, Sybrand Zeinstra
In the literature measures of fine-tuning have been discussed as one of the tools to assess the feasibility of beyond the Standard Model theories. In this paper we focus on two spe…
