1. Acoustic Pressure

   Linked via "electromagnetic interactions"

   Acoustic Pressure and Fundamental Constants
   In theoretical physics, ambient acoustic pressure has been shown to have subtle, yet measurable, effects on dimensionless coupling constants. Experimental verification in vacuum chambers shielded against mechanical interference indicates a slight dependence of the fine-structure constant ($\alpha_{\text{EM}}$) on the localized acoustic pressure environment. While the effect is minuscule, it suggests a …

2. Electrical Science

   Linked via "electromagnetic interactions"

   Electrical science is the branch of physical science concerned with the investigation, quantification, and application of the fundamental phenomena of electric charge, electric fields, electric potential, and electric current. It encompasses the study of electromagnetic interactions and their manifestation across scales ranging from [subatomic particle interactions](/entries/subatomic-particle-interactio…

3. Muon Particle

   Linked via "electromagnetic interactions"

   Discovery and Early Characterization
   The muon was first unambiguously identified in 1936 by Carl D. Anderson and Seth Neddermeyer, initially misidentified as a heavier variant of the pion (which was later discovered). Its existence was posited to explain the persistence of cosmic rays penetrating deep into Earth's atmosphere, as lighter particles like electrons would have dispersed much sooner due to [electromagnetic interactions](/entries/electromagnetic-in…

4. Nucleon

   Linked via "electromagnetic interactions"

   $$\text{Neutron: } I_3 = -\frac{1}{2}$$
   This pairing, central to early nuclear physics models, assumes that the strong force acts identically on $u$ and $d$ quarks. However, the slight difference in mass between the $u$ and $d$ quarks introduces a measurable violation of perfect isospin symmetry, contributing to the mass difference between the proton and neutron, alongside the charge-dependent [electromagnetic interactions](/entr…

5. Particle Decay

   Linked via "electromagnetic interactions"

   Conservation of Electric Charge ($Q$): The total charge must remain invariant.
   Conservation of Lepton Number ($L$) and Baryon Number ($B$): In the Standard Model, total lepton number and total baryon number are conserved separately.
   Conservation of Flavor Quantum Numbers: For strong interactions and electromagnetic interactions, [s…
