Relaxed super self-duality and effective action
Abstract A closed-form expression is obtained for a holomorphic sector of the two-loop Euler–Heisenberg type effective action for N=2 supersymmetric QED derived in hep-th/0308136. In the framework of the background-field...

Structure of mass gap between two spin multiplets
Abstract Studying our semirelativistic potential model and the numerical results, which succeeds in predicting and reproducing recently discovered higher resonances of D, D ...

Surface vacuum energy and stresses for a brane in de Sitter spacetime
Abstract Vacuum expectation values of the surface energy–momentum tensor is investigated for a massless scalar field obeying mixed boundary condition on a brane in de Sitter bulk. To generate the corresponding vacuum surface densities we use the...

Bouncing universe with a non-minimally coupled scalar field on a moving domain wall
Abstract We study dynamics of a dark energy component non-minimally coupled to gravity on a moving domain wall. We use this setup to explain late-time accelerated expansion and crossing of the phantom divide line by the equation of state parameter...

Novel structure for magnetic rotation bands in 60Ni
Abstract The self-consistent tilted axis cranking relativistic mean-field theory based on a point-coupling interaction has been established and applied to investigate systematically the newly observed shears bands in 60Ni. The tilted angles,...

A theory of extra radiation in the Universe
Abstract Recent cosmological observations, such as the measurement of the primordial 4He abundance, CMB, and large scale structure, give preference to the existence of extra radiation component, Δ ...

Gravitational corrections to Yukawa systems
Abstract We compute the gravitational corrections to the running of couplings in a scalar-fermion system, using the Wilsonian approach. Our discussion is relevant for symmetric as well as for broken scalar phases. We find that the Yukawa and quartic ...

General analysis of single top production and W helicity in top decay
Abstract We provide a framework for the analysis of the W boson helicity in the decay of the top quark that is based on a general effective t b W ...

Modular thermal inflation without slow-roll approximation
Abstract We study an inflationary scenario where thermal inflation is followed by fast-roll inflation. This is a rather generic possibility based on the effective potentials of spontaneous symmetry breaking in the context of particle physics models. ...

Non-Hermitian perturbations to the Fritzsch textures of lepton and quark mass matrices
Abstract We show that non-Hermitian and nearest-neighbor-interacting perturbations to the Fritzsch textures of lepton and quark mass matrices can make both of them fit current experimental data very well. In particular, we obtain ...

A predictive seesaw scenario for EDMs
Abstract The generation of electric dipole moments (EDMs) is addressed in the supersymmetric seesaw scenario realized through the exchange of SU ...

Hyperon–nucleon force from lattice QCD
Abstract We calculate potentials between a proton and a Ξ 0 (hyperon with strangeness −2) through the equal-time...

A lattice test of strong coupling behaviour in QCD at finite temperature
Abstract We propose a set of lattice measurements which could test whether the deconfined, quark–gluon plasma, phase of QCD shows strong coupling aspects at temperatures a few times the critical temperature for deconfinement. The measurements refer...

3-branes and uniqueness of the Salam–Sezgin vacuum
Abstract We prove the uniqueness of the supersymmetric Salam–Sezgin (Minkowski)4×S 2 ground state among all non-singular solutions with a four-dimensional Poincaré, de Sitter or anti-de Sitter symmetry. We construct the most...

QCD coherence and correlations of particles with restricted momenta in hadronic Z decays

Nuclear profile dependence of elliptic flow from a parton cascade
Abstract The transverse profile dependence of elliptic flow is studied in a parton cascade model. We compare results from the binary scaling profile to results from the wounded nucleon scaling profile. The impact parameter dependence of elliptic...

Pair-vibrational states in the presence of neutron–proton pairing
Abstract Pair vibrations are studied for a Hamiltonian with neutron–neutron, proton–proton and neutron–proton pairing. The spectrum is found to be rich in strongly correlated, low-lying excited states. Changing the ratio of diagonal to off-diagonal...

Hybrid meson potentials and the gluonic van der Waals force
Abstract The chromoelectric polarizability of mesons governs the strength of the gluonic van der Waals force and therefore of non-quark-exchange processes in hadronic physics. We compute the polarizability of heavy mesons with the aid of lattice...
