The all-loop non-Abelian Thirring model and its RG flow
Abstract We analyze the renormalization group flow in a recently constructed class of integrable σ-models which interpolate between WZW current algebra models and the non-Abelian T-duals of PCM for a simple group G. They are characterized by the...

Phase Separation on a Hyperbolic Lattice
Abstract We report a preliminary numerical study by kinetic Monte Carlo simulation of the dynamics of phase separation following a quench from high to low temperature in a system with a single, conserved, scalar order parameter (a kinetic Ising...

Why 3+1 metric rather than 4+0 or 2+2?
Abstract Why does the physical 4-dimensional space have a 3+1 signature rather than a 4+0 or a 2+2 for its metric? We give a simple explanation based largely on a group-theoretic argument a la Wigner. Applied to flat spaces of higher dimensions the...

Direct evidence for an orbital magnetic quadrupole twist mode in nuclei
Abstract The reactions 58Ni(e,e′) and 58Ni(p,p′) have been studied at kinematics favorable for the excitation of J π =2− states by isovector spin-flip transitions with ΔL=1. There...

On asymmetric orbifolds and the D=5 no-modulus supergravity
Abstract We examine whether any type II asymmetric orbifolds have the same massless spectrum as the dimensional reduction of D=5 simple supergravity, which, besides the eleven-dimensional supergravity, is the only known supergravity above four...

Describing F2 through a finite sum of gluon ladders
Abstract Electroproduction in deep inelastic scattering at HERA is studied in a model considering a finite sum of gluon ladders, associated with a truncation of the BFKL series. The approach contains the bare two gluon exchange and both one and two...

Nuclear enhanced power corrections to DIS structure functions
Abstract We calculate nuclear enhanced power corrections to structure functions measured in deeply inelastic lepton–nucleus scattering in Quantum Chromodynamics (QCD). We find that the nuclear medium enhanced power corrections at order of O(α ...

Vortex correlation functions in Maxwell–Chern–Simons models
Abstract Maxwell–Chern–Simons models in the presence of an instanton–anti-instanton background are studied. The saddle-point configuration corresponds to the creation and annihilation of a vortex localized around the Dirac string needed to support...

Flat directions, doublet–triplet splitting, the monopole problem, and all that
Abstract We discuss a supersymmetric SU(6) grand unified theory with the GUT flat direction being lifted by soft supersymmetry breaking, and the doublet–triplet splitting being achieved with Higgs as a pseudo-Goldstone boson. The theory offers a...

Supersymmetric dark matter—how light can the LSP be?
Abstract Using a very minimal set of theoretical assumptions we derive a lower limit on the LSP mass in the MSSM. We only require that the LSP be the lightest neutralino, that it be responsible for the observed relic density and that the MSSM...

KamLAND and solar neutrino data eliminate the LOW solution
Abstract The KamLAND reactor antineutrino experiment has detected a 3.4σ flux suppression relative to the expectation if no neutrino oscillations occur. We combine KamLAND data with solar neutrino data and show that the LMA solution is the only...

Eight-dimensional topological gravity and its correspondence with supergravity
Abstract A topological theory for Euclidean gravity in eight dimensions can be built by enforcing octonionic self-duality conditions on the spin connection. The eight-dimensional manifold must be of a special type, with G ...

Coexistence of pion condensation and color superconductivity in two flavor quark matter
Abstract We show that the superconducting 2SC phase at high density and normal chiraly broken quark phase at low density is separated by the mixed non-uniform phase along the baryon density line.

Candidates of low-lying dibaryons with strangeness s⩽−5 in a symmetry analysis
Abstract By analyzing the symmetry and the intrinsic nodal surface of the six-quark systems with strangeness s⩽−5, it is shown that, besides the S-wave states [ΩΩ](0,0) , [ΩΞ](1/2,1) , [ΩΞ∗](1/2,0) ...
