Standard-Model Extension - Wikipedia
Standard-Model Extension (SME) is an effective field theory that contains the Standard Model, general relativity, and all possible operators that break Lorentz symmetry. [1][2][3][4][5][6][7][8] Violations of this fundamental symmetry can be studied within this general framework.
Mathematical formulation of the Standard Model - Wikipedia
Theories that lie beyond the Standard Model include various extensions of the standard model through supersymmetry, such as the Minimal Supersymmetric Standard Model (MSSM) and Next-to-Minimal Supersymmetric Standard Model (NMSSM), and entirely novel explanations, such as string theory, M-theory, and extra dimensions.

Beyond The Standard Model | Stanford Institute for Theoretical …
From bizarre, unexplained parameters such as the cosmological constant, Higgs mass, or neutron electric dipole moment to the lack of explanation for observed phenomena such as dark matter and baryogenesis, there is strong evidence that the Standard Model must be extended.
This talk begins with a brief general introduction to the extensions of the Standard Model, reviewing the ideology of e ective eld theories and its practical implications. The central part deals with candidate extensions near the Fermi scale, focusing on some phenomenological aspects of the Minimal Supersymmet-ric Standard Model.
EXTENSIONS OF THE STANDARD MODEL ABSTRACT P. Ramond Physics Department University of Florida Gainesville, FL 32611 In these lectures we focus on several issues that arise in theoretical extensions of the standard model. First we describe the kinds of fermions that can be added to the standard model
Beyond the Standard Model effective field theory: The singlet extended …
Apr 26, 2021 · In this paper, we study the simplest simplified model: the Standard Model extended by a real gauge singlet scalar. In addition to the usual renormalizable interactions, we include dimension-5 interactions of the singlet scalar with Standard Model particles.

May 4, 2016 · We consider the minimal U (1)' extension of the standard model (SM) with the classically conformal invariance, where an anomaly-free U (1)' gauge symmetry is introduced along with three generations of right-handed neutrinos and a U (1)' Higgs field.
