The QCD nature of dark energy
Abstract The origin of the observed dark energy could be explained entirely within the standard model, with no new fields required. We show how the low-energy sector of the chiral QCD Lagrangian, once embedded in a non-trivial spacetime, gives rise...

Spin chains in magnetic field, non-skew-symmetric classical r-matrices and BCS-type integrable systems
Abstract We construct generalized Gaudin systems in an external magnetic field corresponding to arbitrary so ( 3 ) -valued...

Restoration of supersymmetry on the lattice: Two-dimensional supersymmetric Yang–Mills theory
Abstract By numerically investigating the conservation law of the supercurrent, we confirm the restoration of supersymmetry in Sugino's lattice formulation of the two-dimensional N = ...

Erratum to: “A new chiral two-matrix theory for Dirac spectra with imaginary chemical potential” [Nucl. Phys. B 766 (2007) 34–67]
Abstract We correct an algebraic error in the partially quenched correlation functions.

Non-Abelian global vortices
Abstract We study topologically stable non-Abelian global vortices in the U ( N ) linear sigma model. The profile functions of the ...

Vacuum Cherenkov radiation and photon triple-splitting in a Lorentz-noninvariant extension of quantum electrodynamics
Abstract We consider a CPT-noninvariant scalar model and a modified version of quantum electrodynamics with an additional photonic Chern–Simons-like term in the action. In both cases, the Lorentz violation traces back to a spacelike background...

Metal Surface Contamination During Phosphorus Diffusion
Abstract We present work on the impact of surface contamination before phosphorus diffusion on solar cells and life-time samples. Metal surface contamination on KOH/IPA textured Cz wafers was measured by the Sandwich-Etch ICP-MS technique. High...

Homotopy perturbation method for special nonlinear partial differential equations
Abstract In this article, homotopy perturbation method is applied to solve nonlinear parabolic–hyperbolic partial differential equations. Examples of one-dimensional and two-dimensional are presented to show the ability of the method for such...

An ab initio density functional theory calculations on the K2YF5 crystal containing hydroxyl impurities
Abstract High frequency absorption spectral lines not matching any of the chemical constituents were observed while analyzing the infrared experimental spectrum of a K2YF5:Tb+3 sample. We ascribe these lines to the presence of impurities that...

Saving fourth generation and baryon number by living long
Abstract Recent studies of precision electroweak observables have led to the conclusion that a fourth generation is highly constrained. However, we point out that a long-lived fourth generation can reopen a large portion of the parameter space. In...

Left–right asymmetry in semi-inclusive deep inelastic scattering process
Abstract We analyze the left–right asymmetry of pion production in semi-inclusive deep inelastic scattering (SIDIS) process of unpolarized charged lepton on transversely polarized nucleon target. Unlike available treatments, in which some specific...

Extracting Higgs boson couplings using a jet veto
Abstract We show that the Higgs boson's effective couplings to gluons and to weak vector bosons can be extracted simultaneously from an analysis of Higgs plus dijet events by studying the dependence of the observed cross-section upon a third-jet...

BFKL and CCFM evolutions with saturation boundary
Abstract We perform numerical studies of the BFKL and CCFM equations for the unintegrated gluon distribution supplemented with an absorptive boundary which mimics saturation. For BFKL, this procedure yields the same results for the saturation...

Have nucleon decays already been seen?
Abstract Within the framework of the classical theory of general relativity nothing remarkable is expected to happen to an observer falling into a large black hole other than the curious circumstance that after the observer crosses a certain...

Avoiding the big-rip jeopardy in a quintom dark energy model with higher derivatives
Abstract In the framework of a single scalar field quintom model with higher derivative, we construct in this Letter a dark energy model of which the equation of state (EOS) w crosses over the cosmological constant boundary. Interestingly during the ...
