Quantum mechanical calculation of electron spin
Open Physics, 2017 The classical and quantum mechanical methods are used respectively to calculate the electron spin. It is shown that the classical method cannot derive the correct magnetic moment value.

Model-Checking Problems as a Basis for Parameterized Intractability [PDF]
Logical Methods in Computer Science, 2005 Most parameterized complexity classes are defined in terms of a parameterized version of the Boolean satisfiability problem (the so-called weighted satisfiability problem). For example, Downey and Fellow's W-hierarchy is of this form.

A Conservation Law Treatment of Nonlinear KdV Hierarchies
Journal of Mathematics, 2022 We study the hierarchy commonly defined as an infinite sequence of partial differential equations which begins with the Korteweg–de Vries equation and its modified version. An important feature of the hierarchy is its highly nonlinear property.

Journal of High Energy Physics, 2022 In Twin Higgs models the dominant source of fine-tuning is the cancellation of order v 2 /f 2 required to obtain a Standard Model-like Higgs, where v and f are the electroweak and new physics scales, respectively.

Electroweak precision tests of composite Higgs models
Journal of High Energy Physics, 2023 We study constraints on Composite Higgs models with fermion partial compositeness from electroweak precision measurements, including the 2022 W-boson mass result from the CDF collaboration.

Supersymmetric solution of gauge hierarchy problem [PDF]
Pramana, 1982 Some recent developments with respect to the resolution of the gauge hierarchy problem in grand unified theories by supersymmetry are presented. A general argument is developed to show how global supersymmetry maintains the stability of the different mass-scales under perturbative effects.

Towards a non-perturbative approach to the Hierarchy problem
EPJ Web of Conferences, 2018 In this report, based on [1], we suggest that the hierarchy between the Electroweak (EW) and the Planck scales can emerge due to a nonperturbative effect that relates low-energy and strong-gravity physics.
