Modifications to the properties of the Higgs boson
Abstract We explore the impact of new SU ( 3 ) × SU ( 2 ...

QCD condensates with flavor SU(3) symmetry breaking from the instanton vacuum
Abstract We investigate the effects of flavor SU(3)-symmetry breaking on the quark, gluon, and mixed quark–gluon condensates, based on the nonlocal effective chiral action from the instanton vacuum. We take into account the effects of the flavor...

Heavy triplets: electric dipole moments vs. proton decay
Abstract The experimental limit on the electron electric dipole moment constrains the pattern of supersymmetric grand unified theories with right-handed neutrinos. We show that such constraints are already competing with the well known ones derived...

Late-time entropy production due to the decay of domain walls
Abstract It is shown that late-time decay of domain walls can dilute unwanted relics such as moduli, if the universe was dominated by frustrated domain walls with tension σ = ...

Search for low-energy induced depletion of 178Hfm2 at the SPring-8 synchrotron
Abstract Electromagnetic transitions within nuclei reflect specific aspects of nuclear structure. This is particularly true for metastable excited states, or isomers, like 178Hf m2 ( ...

On triple-cut of scattering amplitudes
Abstract It is analysed the triple-cut of one-loop amplitudes in dimensional regularisation within spinor-helicity representation. The triple-cut is defined as a difference of two double-cuts with the same particle contents, and a same propagator...

Skyrmions in the presence of isospin chemical potential
Abstract We analyze the existence of localized finite energy topological excitations on top of the perturbative pion vacuum within the Skyrme model at finite isospin chemical potential and finite pion mass. We show that there is a critical isospin...

Lepton electric dipole moments in supersymmetric type II seesaw model
Abstract We study the lepton electric dipole moments in the framework of the supersymmetric type II seesaw model where the exchange of heavy SU ...

Geometry of orbifolded supersymmetric lattice gauge theories
Abstract We prove that the prescription for construction of supersymmetric lattice gauge theories by orbifolding and deconstruction directly leads to Catterall's geometrical discretization scheme in general. These two prescriptions always give the...

Hadronic-loop induced mass shifts in scalar heavy–light mesons
Abstract We calculate the mass shifts of heavy–light scalar mesons due to hadronic loops under the assumption that these vanish for the groundstate heavy–light mesons. The results show that the masses calculated in quark models can be reduced...

Creation of Kerr–de Sitter black hole in all dimensions
Abstract We discuss quantum creation scenario of Kerr–de Sitter black hole in all dimensions. We show that its relative creation probability is the exponential to the entropy of the black hole, using a topological argument. The action of the...

Dynamical CP violation in the early Universe
Abstract Following earlier ideas of Dolgov, we show that the asymmetrical dynamical evolution of fields in the early Universe provides a new source for CP violation. This can lead to baryogenesis without any additional CP-violating interactions. The ...

Channeling of high-energy particles in a multi-wall nanotube
Abstract Channeling of high-energy particles in straight and bent multi-wall nanotubes (MWNT) has been studied in computer simulations and compared to the channeling properties of single-wall nanotubes (SWNT) and bent crystal lattices. It is...

Short-time quantum propagator and Bohmian trajectories
Abstract We begin by giving correct expressions for the short-time action following the work Makri–Miller. We use these estimates to derive an accurate expression modulo Δ ...

Do observations favour Galileon over quintessence?
Abstract We study the Galileon scalar field model arising as a decoupling limit of the Dvali–Gababdaze–Porrati (DGP) construction for the late time acceleration of the universe. The model has one extra Galileon correction term over and above the...

Generalized Estimating Equations for Zero-Inflated Spatial Count Data
Abstract This paper consolidates the zero-inflated Poisson model for count data with excess zeros proposed by Lambert (1992) and the two-component model approach for serial correlation among repeated observations proposed by Dobbie and Welsh (2001)...
