Decisive test for the pomeron at the Tevatron
Abstract We propose a new measurement to be performed at the Tevatron which can be decisive to distinguish between pomeron-based and soft color interaction models of hard diffractive scattering.

Phase transition in the fine structure constant
Abstract Within the context of mass-varying neutrinos, we construct a cosmological model that has a phase transition in the electromagnetic fine structure constant α at a redshift of 0.5. The model accommodates hints of a time variable α in quasar...

New inhomogeneous Einstein metrics on sphere bundles over Einstein–Kähler manifolds
Abstract We construct new complete, compact, inhomogeneous Einstein metrics on S m+2 sphere bundles over 2n-dimensional Einstein–Kähler spaces K 2n , for all n⩾1 ...

WWZ, WWH, and ZZH couplings in the dynamical gauge–Higgs unification in the warped spacetime
Abstract In the dynamical gauge–Higgs unification in the Randall–Sundrum warped spacetime, where the 4D Higgs field is unified with gauge fields and the electroweak symmetry is dynamically broken by the Hosotani mechanism, the trilinear couplings...

On the universality of Goldstino action
Abstract We find the Goldstino action descending from the N=1 Goldstone–Maxwell superfield action associated with the spontaneous partial supersymmetry breaking, N=2 to N=1, in superspace. The new Goldstino action has higher (second-order) spacetime ...

Search for three-body force effects in neutron–deuteron scattering at 95 MeV
Abstract The neutron–deuteron ( n d ) elastic scattering differential cross section has been measured at 95 MeV incident neutron...

Kohn–Sham density functional inspired approach to nuclear binding
Abstract A non-relativistic nuclear density functional theory is constructed, not as done most of the time, from an effective density dependent nucleon–nucleon force but directly introducing in the functional results from microscopic nuclear and...

Radiative transmission of lepton flavor hierarchies
Abstract We discuss a one loop model for neutrino masses which leads to a seesaw-like formula with the difference that the charged lepton masses replace the unknown Dirac mass matrix present in the usual seesaw case. This is a considerable reduction ...

Kinks in discrete light cone quantization
Abstract We investigate non-trivial topological structures in discrete light cone quantization (DLCQ) through the example of the broken symmetry phase of the two-dimensional φ 4 theory using antiperiodic boundary condition...

On the excluded space in applications of Feshbach projection formalism
Abstract Various model applications in nuclear structure and reactions have been formulated starting with the Feshbach projection formalism. In recent studies a truncated excluded space has been enumerated to facilitate calculation and identify a...

Reply to: “Comment to: ‘Fine structure constant in the spacetime of a cosmic string‴ [Phys. Lett. B 621 (2005) 318]
Abstract In this Reply, using E.R. Bezerra de Mello's comment, I correct calculations and results presented in [Phys. Lett. B 614 (2005) 140–142] about fine structure constant in the spacetime of a cosmic string.

Composite Higgs from higher representations
Abstract We investigate new models of dynamical electroweak symmetry breaking resulting from the condensation of fermions in higher representations of the technicolor group. These models lie close to the conformal window, and are free from the...

Collinear photon exchange in the beam normal polarization asymmetry of elastic electron–proton scattering
Abstract The parity-conserving single-spin beam asymmetry of elastic electron–proton scattering is induced by an absorptive part of the two-photon exchange amplitude. We demonstrate that this asymmetry has logarithmic and double-logarithmic...

Inflaton mass in the νMSM inflation
Abstract We analyze the reheating in the modification of the νMSM (Standard Model with three right handed neutrinos with masses below the electroweak scale) where one of the sterile neutrinos, which provides the Dark Matter, is generated in decays...

Heavy-quarkonium interaction in QCD at finite temperature
Abstract We explore the temperature dependence of the heavy-quarkonium interaction based on the Bhanot–Peskin leading order perturbative QCD analysis. The Wilson coefficients are computed solving the Schrödinger equation in a screened Coulomb...

Tube of (circle F, D0, D2) bound state in Melvin background
Abstract By using the Born–Infeld action we show that the m circular fundamental strings, n D2-branes and k D0-branes could become a tubular bound state which is prevented from collapsing by the magnetic force in the Melvin background. However, if...

Holographic cosmological constant and dark energy
Abstract A general holographic relation between UV and IR cutoff of an effective field theory is proposed. Taking the IR cutoff relevant to the dark energy as the Hubble scale, we find that the cosmological constant is highly suppressed by a...

Gravitational spectrum of black holes in the Einstein–Aether theory
Abstract Evolution of gravitational perturbations, both in time and frequency domains, is considered for a spherically symmetric black hole in the non-reduced Einstein–Aether theory. It is shown that real oscillation frequency and damping rate are...

Lorentz violation and black-hole thermodynamics: Compton scattering process
Abstract A Lorentz-noninvariant modification of quantum electrodynamics (QED) is considered, which has photons described by the nonbirefringent sector of modified Maxwell theory and electrons described by the standard Dirac theory. These photons and ...
