Hi...I do not understand why the charges of a QFT belong to the root lattice of the gauge group...can somebody explain it please??
QFT stands for Quantum Field Theory, which is a theoretical framework used to study the behavior of particles and fields at a quantum level. It combines elements of quantum mechanics and special relativity to describe the interactions between particles.
In QFT, charges refer to properties of particles that are conserved (i.e. they do not change) during interactions. These charges can be related to fundamental forces, such as electric charge, color charge, and flavor charge.
A gauge group is a mathematical concept used in QFT to describe the symmetries of a physical system. It represents the possible transformations that a system can undergo without changing its underlying physics.
Root lattices are mathematical structures used to describe and classify the symmetries of physical systems in QFT. They consist of a set of vectors that form a lattice (a grid-like structure) in a higher-dimensional space.
In QFT, the charges of particles are related to the symmetries of the system, which are described by the gauge group. The root lattice is then used to categorize the possible symmetries and their corresponding charges, providing a comprehensive framework for understanding the behavior of particles in QFT.
