Landau Pole: A Theoretical Limit of Quantum Field Theories

The Landau pole is a concept in quantum field theory referring to a hypothetical energy scale at which a coupling

Running Coupling Constants: Energy-Dependent Interaction Strengths

In quantum field theory, running coupling constants describe how the strength of fundamental interactions—such as the electromagnetic, weak, and strong

Asymptotic Safety: A Framework for a Consistent Quantum Theory of Gravity

Asymptotic safety is a theoretical idea suggesting that quantum gravity—the attempt to unify general relativity with quantum mechanics—might be made

Proton Decay: A Key Prediction of Grand Unified Theories

Proton decay is a hypothetical process in which the proton, considered a stable building block of matter, would spontaneously transform

Muon g–2 Anomaly: A Possible Sign of New Physics

The muon g–2 anomaly refers to a persistent discrepancy between the predicted and experimentally measured value of the magnetic moment

Neutrinoless Double Beta Decay: A Window into the Nature of Neutrinos

Neutrinoless double beta decay is a hypothetical nuclear process that, if observed, would reveal that neutrinos are their own antiparticles—a

Sterile Neutrinos: Hypothetical Particles Beyond the Standard Model

Sterile neutrinos are a proposed type of neutrino that do not interact via the standard weak nuclear force, unlike the

Neutrino Oscillations: Evidence of Mass and Changing Identity

Neutrino oscillations are a quantum phenomenon in which neutrinos change their type, or “flavor,”—electron, muon, or tau—as they travel through

Sakharov Conditions: Requirements for Creating a Matter-Dominated Universe

The Sakharov conditions are three fundamental criteria proposed by physicist Andrei Sakharov in 1967 to explain how the early universe

Baryogenesis: Explaining the Matter-Antimatter Imbalance

Baryogenesis is a theoretical process that aims to explain why the observable universe is made almost entirely of matter, with
