Chiral symmetry breaking in the Nambu-Jona-Lasinio model in curved spacetime with a nontrivial topology.
We discuss the phase structure (in the 1/N -expansion) of the Nambu-Jona-Lasinio model in curved spacetime with non-trivial topology M3 × S. The evaluation of the effective potential of the composite field ψ̄ψ is presented in the linear curvature approximation (topology is treated exactly) and in the leading order of the 1/N -expansion. The combined influence of topology and curvature to the pha...
متن کاملElectroweak Symmetry Breaking as a Consequence of Compact Dimensions
It has been shown recently that the Higgs doublet may be composite, with the left-handed top-bottom doublet and a new right-handed anti-quark as constituents bound by some four-quark operators with non-perturbative coefficients. I show that these operators are naturally induced if there are extra spatial dimensions with a compactification scale in the multi-TeV range. The Higgs compositness is ...

متن کاملThe Overlap - Dirac Operator : Topology and Chiral Symmetry Breaking
In these proceedings, we review some basic properties of the overlap Dirac operator and how its index can be computed by spectral flow techniques. One of the side results is that for fermions in the adjoint representation of SU(N) we find evidence for fractional topological charge. The presentation is pedagogical with the intent of illustrating the origin of numerical difficulties in simulating...
متن کاملSymmetry, Symmetry Breaking and Topology
The ground state of a system with symmetry can be described by a group G. This symmetry groupG can be discrete or continuous. Thus for a crystalG is a finite group while for the vacuum state of a grand unified theory G is a continuous Lie group. The ground state symmetry described by G can change spontaneously from G to one of its subgroups H as the external parameters of the system are modifie...
