Symmetry Breaking in Classical Particle Mechanics
The U(1) gauge field is usually induced from the gauge principle, that is, the extension of global U(1) phase transformation for matter field. However the phase itself is realized only for quantum theory. This makes us feel that the gauge fields are induced only in quantum theory by gauge principle. To make clear this point, we start from the non-relativistic classical particle, and we transfor...
متن کاملReplica Symmetry Breaking in Trajectories of a Driven Brownian Particle.
We study a Brownian particle passively driven by a field obeying the noisy Burgers' equation. We demonstrate that the system exhibits replica symmetry breaking in the path ensemble with the initial position of the particle being fixed. The key step of the proof is that the path ensemble with a modified boundary condition can be exactly mapped onto the canonical ensemble of directed polymers.
متن کاملLarge Lepton Number and High Temperature Symmetry Breaking in MSSM
It is known that a large neutrino number, of the order of a few percent of the entropy of the universe, leads to symmetry breaking at high temperature. We show here that in the minimal supersymmetric standard model (MSSM) this implies the breaking of electromagnetic charge invariance at T ≫ MW allowing for the solution of the monopole problem.

متن کاملA note on the compatibility of static symmetry breaking constraints and dynamic symmetry breaking methods
Adding static constraints (e.g. lexicographic constraints) and modifying a backtracking search procedure to dynamically eliminate the consideration of symmetrically equivalent states (e.g. SBDS and SBDD) are two common methods for breaking symmetry, with different advantages and disadvantages. It is natural to try to combine these in order to try to harness the strengths of each. However, in so...
متن کاملSpontaneous Symmetry Breaking as a Basis of Particle Mass
Electroweak theory joins electromagnetism with the weak force in a single quantum field theory, ascribing the two fundamental interactions—so different in their manifestations—to a common symmetry principle. How the electroweak gauge symmetry is hidden is one of the most urgent and challenging questions facing particle physics. The provisional answer incorporated in the “standard model” of part...
