GENERATORS OF SU(2) , SU(3) AND U(2) || ELEMENTARY PARTICLE PHYSICS || msc PHYSICS

with exam notes In physics, SU(2), SU(3), and U(2) are groups used to describe symmetries in quantum mechanics and particle physics. Here are brief explanations of what each group represents and their corresponding generators: 1. *SU(2) (Special Unitary Group of degree 2):* It describes the symmetries of two-state quantum mechanical systems, such as spin-1/2 particles. The generators of SU(2) are the Pauli matrices: σ₁, σ₂, and σ₃. 2. *SU(3) (Special Unitary Group of degree 3):* It describes the symmetries of three-state quantum mechanical systems, such as quarks an.d the strong force. The generators of SU(3) are the eight Gell-Mann matrices, which are analogous to the Pauli matrices for SU(2). 3. *U(2) (Unitary Group of degree 2):* It describes the symmetries of two-state quantum mechanical systems with no restriction on the determinant of the matrices. The generators of U(2) include the Hermitian matrices, which form a basis for the Lie algebra associated with U(2). These groups and their generators play crucial roles in understanding fundamental interactions and symmetries in theoretical physics. #elementaryparticlephysics #physics #particlephysics #QuantumMechanics #ParticlePhysics #GroupTheory #Symmetry #SU2 #SU3 #U2 #PauliMatrices #GellMannMatrices #LieAlgebra 1.
