Comment on: “Reduction of static field equation of Faddeev model to first order PDE” [Phys. Lett. B 652 (2007) 384]
Abstract The authors of the article [M. Hirayama, C.-G. Shi, Phys. Lett. B 652 (2007) 384, arXiv: 0707.2207] propose an interesting method to solve the Faddeev model by reducing it to a set of first order PDEs. They first construct a vectorial...

Flavor dependence of the S-parameter
Abstract We extend the results of Sannino (2010) [1] by computing the S-parameter at two loops in the perturbative region of the conformal window. Consistently using the expression for the location of the infrared fixed point at the two-loop order...

The fate of black holes in an accelerating universe
Abstract Babichev, Dokuchaev and Eroshenko have recently found that accretion of phantom energy onto a black hole induces a gradual decrease of the black hole mass, and that masses of all possible black holes tend to zero as a result of this process ...

Littlest Higgs model and top-charm production at high-energy linear colliders
Abstract Due to the presence of extra top quark T in the little Higgs models, the CKM matrix is not unitary and the flavor changing neutral currents may exist at the tree level. In the context of the littlest Higgs (LH) model, we discuss the...

CPT/Lorentz invariance violation and neutrino oscillation
Abstract We analyze the consequences of violation of Lorentz and CPT invariance in the massless neutrino sector by deforming the canonical anti-commutation relations for the fields. We show that, for particular choices of the deformation,...

Meson-exchange currents and quasielastic neutrino cross sections in the superscaling approximation model
Abstract We evaluate the quasielastic double differential neutrino cross sections obtained in a phenomenological model based on the superscaling behavior of electron scattering data. We compare our results with the recent experimental data for...

Decay constants of P-wave mesons
Abstract Decay constants of P-wave mesons are computed in the framework of instantaneous Bethe–Salpeter method (Salpeter method). By analyzing the parity and possible charge conjugation parity, we give the relativistic configurations of wave...

Orbifold unification for the gauge and Higgs fields and their couplings
Abstract We present an orbifold GUT model in which the Higgs trilinear couplings are unified with the three Standard Model gauge couplings. The model is constructed as an N = 2 ...

Electron electric dipole moment induced by octet-colored scalars
Abstract An appended sector of two octet-colored scalars, each an electroweak doublet, is an interesting extension of the simple two Higgs doublet model motivated by the minimal flavor violation. Their rich CP violating interaction gives rise to a...

Probing matter radii of neutron-rich nuclei by antiproton scattering
Abstract We propose to use intermediate energy antiprotons to investigate the sizes of stable and neutron-rich exotic nuclei by measurements of the p ¯ ...

Black hole thermodynamics and the factor of 2 problem
Abstract We show that the recent tunneling formulas for black hole radiation in static, spherically symmetric spacetimes follow as a consequence of the first law of black hole thermodynamics and the area-entropy relation based on the radiation...

Analysis of Multifractals in Game Behaviors
Abstract We study the diffusive process and the multifractal property in the Baduk. We are able to ascertain the superdiffusive process that the dispersion is proportional to tɛ with the scaling exponent ɛ =1.66±0.26 for our model. After simulating...

The XXZ Heisenberg model on random surfaces
Abstract We consider integrable models, or in general any model defined by an R-matrix, on random surfaces, which are discretized using random Manhattan lattices. The set of random Manhattan lattices is defined as the set dual to the lattice random...

Exploring the role of axions and other WISPs in the dark universe
Abstract Axions and other very weakly interacting slim particles (WISPs) may be non-thermally produced in the early universe and survive as constituents of the dark universe. We describe their theoretical motivation and their phenomenology. A huge...

Supersymmetric DBI inflation
Abstract We discuss a supersymmetric version of DBI (Dirac–Born–Infeld) inflation, which is a typical inflation model in string cosmology. The supersymmetric DBI action together with a superpotential always leads to correction terms associated with...
