Has the origin of the third-family fermion masses been determined?
Journal of High Energy Physics, 2021 Precision measurements of the Higgs couplings are, for the first time, directly probing the mechanism of fermion mass generation. The purpose of this work is to determine to what extent these measurements can distinguish between the tree-level mechanism ...

Constraining Dark Boson Decay Using Neutron Stars
Universe, 2023 Inspired by the well-known anomaly in the lifetime of the neutron, we investigated its consequences inside neutron stars. We first assessed the viability of the neutron decay hypothesis suggested by Fornal and Grinstein within neutron stars, in terms of ...

Radiative muon mass models and (g − 2) μ
Journal of High Energy Physics, 2021 Recent measurements of the Higgs-muon coupling are directly probing muon mass generation for the first time. We classify minimal models with a one-loop radiative mass mechanism and show that benchmark models are consistent with current experimental ...

Fundamental Interactions, 2007 The nature of the main constituents of the mass of the universe is one of the outstanding riddles of cosmology and astro-particle physics. Current models explaining the evolution of the universe, and measurements of the various components of its mass, all have in common that an appreciable contribution to that mass is non-luminous and non-baryonic, and

Modified dark matter: Relating dark energy, dark matter and baryonic matter [PDF]
International Journal of Modern Physics D, 2018 Modified dark matter (MDM) is a phenomenological model of dark matter, inspired by gravitational thermodynamics. For an accelerating universe with positive cosmological constant ([Formula: see text]), such phenomenological considerations lead to the emergence of a critical acceleration parameter related to [Formula: see text].

Combining outlier analysis algorithms to identify new physics at the LHC
Journal of High Energy Physics, 2021 The lack of evidence for new physics at the Large Hadron Collider so far has prompted the development of model-independent search techniques. In this study, we compare the anomaly scores of a variety of anomaly detection techniques: an isolation forest ...

Energy-releasing Process for the 2013 May 13 X1.7 Limb Flare: A Continued Study
The Astrophysical Journal, 2023 In this paper, we reanalyze the X1.7 class limb flare that occurred on 2013 May 13 (SOL2013-05-13T01:56 UT), concentrating on the energy-releasing process using microwave observations mainly made by Nobeyama and X-ray observations made by RHESSI.

A real triplet-singlet extended Standard Model: dark matter and collider phenomenology
Journal of High Energy Physics, 2021 We examine the collider and dark matter phenomenology of the Standard Model extended by a hypercharge-zero SU(2) triplet scalar and gauge singlet scalar.
