Vector–axial-vector mixing from a chiral effective field theory at finite temperature
We study the vector–axial-vector mixing in a hot medium and its evolution toward the chiral phase transition using different symmetry restoration scenarios based on the generalized hidden local symmetry framework. We show that the presence of the a1 meson reduces the vector spectral function around the meson mass and enhances it around the a1 meson mass. The coupling strength of a1 to and vanis...
متن کاملProperties of vector mesons at finite temperature: Effective Lagrangian approach.
The properties of ρ-mesons at finite temperature (T ) are examined with an effective chiral lagrangian in which vector and axial-vector mesons are included as massive Yang-Mills fields of the chiral symmetry. It is shown that, at T 2 order, the effective mass is not changed but only the mixing effect in vector and axial-vector correlator appears. PACS numbers : 25.75+r, 11.10.Wx, 11.30.Rd Types...
متن کاملThe 3d Effective Field Theory for Finite Temperature Scalar Electrodynamics
The effective field theory approach to high temperature field theory can be used to study the phase transition in theories with spontaneously broken symmetry. I construct a sequence of two effective three–dimensional field theories which are valid on successively longer distance scales for a specific model: model: N charged scalars coupled to a U(1) gauge field. The resulting effective Lagrangi...

We discuss the recent development of effective field theories for quarkonium at finite temperature.
متن کاملCharge–dependent nucleon–nucleon potential from chiral effective field theory
We discuss charge symmetry and charge independence breaking in a chiral effective field theory approach for few–nucleon systems based on a modified Weinberg power counting. We construct a two–nucleon potential with bound and scattering states generated by means of a properly regularized Lippmann–Schwinger equation. We systematically introduce strong isospin–violating and electromagnetic operato...
