We study an extension of the Standard Model featuring a hidden sector that
consists of a new scalar charged under a new SU(N)D gauge group , singlet under all Standard
Model gauge interactions, and coupled with the Standard Model only via a Higgs
portal. We assume that the theory is classically conformal, with electroweak symmetry
breaking dynamically induced via the Coleman-Weinberg mechanism operating in the hidden
sector. Due to the symmetry breaking pattern, the SU(N)D gauge group is completely
Higgsed and the resulting massive vectors of the hidden sector constitute a stable dark
matter candidate. We perform a thorough scan over the parameter space of the model
at different values of N = 2, 3, and 4, and investigate the phenomenological constraints.
We find that N = 2, 3 provide the most appealing model setting in light of present data
from colliders and dark matter direct search experiments. We expect a heavy Higgs to be
discovered at LHC by the end of Run II or the N = 3 model to be ruled out.

Beyond the standard model via extended symmetries and dark matter
Alanne, Tommi (University of Jyväskylä, 2015)In this thesis, we discuss ideas of how to go beyond the Standard Model (SM) of particle physics to incorporate the cosmological observations of dark matter and matter–antimatter asymmetry, and to address the theoretical ... -

Prospects for beyond the Standard Model physics searches at the Deep Underground Neutrino Experiment
DUNE Collaboration (Springer, 2021)The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a ... -
Determination of the θ23 octant in long baseline neutrino experiments within and beyond the standard model
Das, C. R.; Pulido, João; Maalampi, Jukka; Vihonen, Sampsa (American Physical Society, 2018)The recent data indicate that the neutrino mixing angle θ 23 deviates from the maximal-mixing value of 45°, showing two nearly degenerate solutions, one in the lower octant (LO) ( θ 23 < 4 5 ° ) and one in the ... -
Relevance and guidelines of radiation effect testing beyond the standards for electronic devices and systems used in space and at accelerators
Coronetti, Andrea (Jyväskylän yliopisto, 2021)Radiation effect testing is a key element of the radiation hardness assurance process needed to ensure the compliance with respect to the reliability and availability requirements of both space and accelerator electronic ...
