Quenched mesonic spectrum at large N
Luigi Del Debbio, Biagio Lucini, Agostino Patella +1
We compute the masses of the and of the mesons in the quenched approximation on a lattice with fixed lattice spacing for SU() gauge theory…
Static Interactions of non-Abelian Vortices
Roberto Auzzi, Minoru Eto, Walter Vinci
Interactions between non-BPS non-Abelian vortices are studied in non-Abelian U(1) x SU(N) extensions of the Abelian-Higgs model in four dimensions. The distinctive feature of a non…
A Note on Chern-Simons Solitons - a type III vortex from the wall vortex
Stefano Bolognesi, Sven Bjarke Gudnason
We study some properties of topological Chern-Simons vortices in 2 + 1 dimensions. As has already been understood in the past, in the large magnetic flux limit, they are well descr…
On manifestly sp(2) invariant formulation of quadratic higher spin Lagrangians
K. B. Alkalaev
The Lagrangian frame-like formulation of free higher spin symmetric bosonic AdS(d) fields is given within a manifestly sp(2) invariant framework. It is designed to deal with infini…
Type I Non-Abelian Superconductors in Supersymmetric Gauge Theories
Roberto Auzzi, Minoru Eto, Walter Vinci
Non-BPS non-Abelian vortices with CP^1 internal moduli space are studied in an N=2 supersymmetric U(1) x SU(2) gauge theory with softly breaking adjoint mass terms. For generic int…
Equivalence of QCD in the epsilon-regime and chiral Random Matrix Theory with or without chemical potential
Francesco Basile, Gernot Akemann
We prove that QCD in the epsilon-regime of chiral Perturbation Theory is equivalent to chiral Random Matrix Theory for zero and both non-zero real and imaginary chemical potential…
Reduced Hamiltonian for intersecting shells
Francesco Fiamberti, Pietro Menotti
The gauge usually adopted for extracting the reduced Hamiltonian of a thin spherical shell of matter in general relativity, becomes singular when dealing with two or more intersect…
Dynamics of Domain Wall Networks
Minoru Eto, Toshiaki Fujimori, Takayuki Nagashima +3
Networks or webs of domain walls are admitted in Abelian or non-Abelian gauge theory coupled to fundamental Higgs fields with complex masses. We examine the dynamics of the domain…
Magnetic strings in Lattice QCD as Nonabelian Vortices
A. Gorsky, V. Zakharov
Lattice studies indicate existence of magnetic strings in QCD vacuum. We argue that recently found nonabelian strings with rich worldsheet dynamics provide a proper pattern for the…
Renormalization of Lorentz violating theories
Damiano Anselmi, Milenko Halat
We classify the unitary, renormalizable, Lorentz violating quantum field theories of interacting scalars and fermions, obtained improving the behavior of Feynman diagrams by means…
Non-Abelian vortices and monopoles in SO(N) theories
Luca Ferretti, Sven Bjarke Gudnason, Kenichi Konishi
Non-Abelian BPS vortex solutions are constructed in N=2 theories with gauge groups SO(N)\times U(1). The model has N_f flavors of chiral multiplets in the vector representation of…
SU(N) gauge theories in the presence of a topological term
Luigi Del Debbio, Haralambos Panagopoulos, Ettore Vicari
We review recent results on the theta dependence of the ground-state energy and spectrum of four-dimensional SU(N) gauge theories, where theta is the coefficient of the CP-violatin…
QCD String as Vortex String in Seiberg-Dual Theory
Minoru Eto, Koji Hashimoto, Seiji Terashima
We construct a classical vortex string solution in a Seiberg-dual theory of N=1 supersymmetric SO(N_c) QCD which flows to a confining phase. We claim that this vortex string is a Q…
Improved Schwinger-DeWitt techniques for higher-derivative perturbations of operator determinants
Damiano Anselmi, Anna Benini
We consider higher-derivative perturbations of quantum gravity and quantum field theories in curved space and investigate tools to calculate counterterms and short-distance expansi…
On the moduli space of semilocal strings and lumps
Minoru Eto, Jarah Evslin, Kenichi Konishi +5
We study BPS non-abelian semilocal vortices in U(Nc) gauge theory with Nf flavors, Nf > Nc, in the Higgs phase. The moduli space for arbitrary winding number is described using the…
A Bound Quantum Particle in a Riemann-Cartan space with Topological Defects and Planar Potential
S. A. Ali, C. Cafaro, S. Capozziello +1
Starting from a continuum theory of defects, that is the analogous to three-dimensional Einstein-Cartan-Sciama-Kibble gravity, we consider a charged particle with spin 1/2 propagat…
Baryon currents in QCD with compact dimensions
Biagio Lucini, Agostino Patella, Claudio Pica
On a compact space with non-trivial cycles, for sufficiently small values of the radii of the compact dimensions, SU(N) gauge theories coupled with fermions in the fundamental repr…
