Little Higgs Models and Precision Electroweak Data
Roberto Casalbuoni, Aldo Deandrea, Micaela Oertel
We study the low energy limit of Little Higgs models. The method consists in eliminating the heavy fields using their classical equations of motion in the infinite mass limit. Afte…
Two tricritical lines from a Ginzburg-Landau expansion: application to the LOFF phase
R. Casalbuoni, G. Tonini
We study the behavior of the two plane waves configuration in the LOFF phase close to T=0. The study is performed by using a Landau-Ginzburg expansion up to the eighth order in the…
Inhomogeneous Color Superconductivity
R. Casalbuoni
We discuss the possibility that in finite density QCD an anisotropic phase is realized. This case might arise for quarks with different chemical potential and/or different masses.…
Inhomogeneous Superconductivity in Condensed Matter and QCD
Roberto Casalbuoni, Giuseppe Nardulli
Inhomogeneous superconductivity arises when the species participating in the pairing phenomenon have different Fermi surfaces with a large enough separation. In these conditions it…
Ladder-QCD at finite isospin chemical potential
A. Barducci, R. Casalbuoni, G. Pettini +1
We use an effective QCD model (ladder-QCD) to explore the phase diagram for chiral symmetry breaking and restoration at finite temperature with different quark chemical poten…
Aspects of the Color Flavor Locking phase of QCD in the Nambu-Jona Lasinio approximation
R. Casalbuoni, R. Gatto, G. Nardulli +1
We study two aspects of the CFL phase of QCD in the NJL approximation. The first one is the issue of the dependence on μof the ultraviolet cutoff in the gap equation, which is solv…
