Four- and eight-fermion interactions in a space-time with non-trivial topology
نویسنده
چکیده
The phase structure of an eight-fermion interaction model is investigated in a compact space-time with non-trivial topology, M⊗S. The phase boundary dividing the symmetric and the broken phase is shown as a function of the space-time dimensions. It is found that the eight-fermion interaction does not modify the phase boundary for the chiral symmetry breaking.

Dynamical Symmetry Breaking in Flat Space with Non-trivial Topology
We consider a four-fermion theory as a simple model of dynamical symmetry breaking in flat space with non-trivial topology, motivated from recent studies in similar considerations in curved space. The phase structure is investigated, by developing a useful formalism to evaluate the effective potential in arbitrary compactified flat space in 3and 4-dimensional spacetime. The phase structure is s...
متن کاملNon-Relativistic Limit of Neutron Beta-Decay Cross-Section in the Presence of Strong Magnetic Field
One of the most important reactions of the URCA that lead to the cooling of a neutron star, is neutron beta-decay ( ). In this research, the energy spectra and wave functions of massive fermions taking into account the Anomalous Magnetic Moment (AMM) in the presence of a strong changed magnetic field are calculated. For this purpose, the Dirac-Pauli equation for charged and neutral fermions is ...

The effective potential in the model introduced by Buchbinder-Inagaki-Odintsov (BIO) [1] which represents SUSY NJL model non-minimally coupled with the external gravitational field is found. The topology of the space is considered to be non-trivial. Chiral symmetry breaking under the action of external curvature and non-trivial topology is investigated. Nambu-Jona-Lasinio (NJL) model represents...
متن کاملA COVERING PROPERTY IN PRINCIPAL BUNDLES
Let $p:Xlo B$ be a locally trivial principal G-bundle and $wt{p}:wt{X}lo B$ be a locally trivial principal $wt{G}$-bundle. In this paper, by using the structure of principal bundles according to transition functions, we show that $wt{G}$ is a covering group of $G$ if and only if $wt{X}$ is a covering space of $X$. Then we conclude that a topological space $X$ with non-simply connected universal...
متن کاملContinuous Chiral Transition in Strongly Coupled Compact Qed with the Standard Torus Topology
We analyze the phase diagram of compact QED on the torus with a chirally symmetric four fermion interaction. Inside a mean field approximation for the four fermion term, a line of first order phase transitions and another one of second order are found in the (β, G) plane. Approaching the second order line a continuum limit can be defined. Critical exponents vary along this line in a similar way...
