We argue that the SM in the Higgs phase does not suffer form a “hierarchy problem” and that similarly the “cosmological constant problem” resolves itself if we understand the SM as a low energy effective theory emerging from a cut-off medium at the Planck scale. We discuss these issues under the condition of a stable Higgs vacuum, which allows to extend the SM up to the Planck length. The bare Higgs boson mass then changes sign below the Planck scale, such the the SM in the early universe is in… Expand

The Hierarchy Problem and the Cosmological Constant Problem Revisited
We argue that the Standard Model (SM) in the Higgs phase does not suffer from a “hierarchy problem” and that similarly the “cosmological constant problem” resolves itself if we understand the SM as aExpand
Models of the LHC diphoton excesses valid up to the Planck scale
We discuss a possibility to explain the LHC diphoton excesses at 750 GeV by the new scalar X that couples to the gauge bosons through the loop of new massive particles with standard model charges. WeExpand
Vanishing Higgs potential in minimal dark matter models
Abstract We consider the Standard Model with a new particle which is charged under SU ( 2 ) L with the hypercharge being zero. Such a particle is known as one of the dark matter (DM) candidates. WeExpand
Mirror QCD and Cosmological Constant
An analog of Quantum Chromo Dynamics (QCD) sector known as mirror QCD (mQCD) can affect the cosmological evolution due to a non-trivial contribution to the Cosmological Constant analogous to thatExpand


The hierarchy problem of the electroweak Standard Model revisited
A careful renormalization group analysis of the electroweak Standard Model, considered as a low energy effective theory, reveals that there is no hierarchy problem in the broken phase of the SM. InExpand
Living beyond the edge: Higgs inflation and vacuum metastability
The measurements of the Higgs mass and top Yukawa coupling indicate that we live in a very special universe, at the edge of the absolute stability of the electroweak vacuum. If fully stable, theExpand
Renormalization group equation, the naturalness problem, and the understanding of the Higgs mass term
The naturalness problem might be studied on the complex two dimensional plane with the technique of dimensional regularization(DREG). The Renormalization group equation(RGE) of the Higgs mass on theExpand
Cosmological constant and vacuum energy: old and new ideas
The cosmological constant (CC) term in Einstein's equations, Λ, was first associated to the idea of vacuum energy density. Notwithstanding, it is well-known that there is a huge, in fact appalling,Expand
Naturalness, chiral symmetry, and spontaneous chiral symmetry breaking
A properly called “naturalness” is imposed on gauge theories. It is an order-of-magnitude restriction that must hold at all energy scales μ. To construct models with complete naturalness forExpand
The early Universe
In the past few years one of the most exciting areas of research in physics has been the interdisciplinary field of cosmology and particle physics. The NSF's Institute for Theoretical Physics inExpand
Self-consistence of the Standard Model via the renormalization group analysis
A short review of recent renormalization group analyses of the self-consistence of the Standard Model is presented.
