Conformal quantum mechanics as the CFT1 dual to AdS2
Abstract A ( 0 + 1 )-dimensional candidate theory for the CFT1 dual to AdS2 is discussed. The quantum mechanical system does not have a ground state that is ...

Charge radii and structural evolution in Sr, Zr, and Mo isotopes
Abstract The evolution of the ground-state nuclear shapes in neutron-rich Sr, Zr, and Mo isotopes, including both even-even and odd-A nuclei, is studied within a self-consistent mean-field approximation based on the D1S–Gogny interaction. Neutron...

Gauge field strength tensor from the overlap Dirac operator
Abstract We derive the classical continuum limit of the operator tr s σ ...

On the possible running of the cosmological “constant”
Abstract Despite the many outstanding cosmological observations leading to a strong evidence for a non-vanishing cosmological constant (CC) term Λ in the gravitational field equations, the theoretical status of this quantity seems to be lagging well ...

Dynamical chiral symmetry breaking and its restoration for an accelerated observer
Abstract Based on the Hawking–Unruh thermalization theorem, we investigate the phenomenon of the dynamical chiral symmetry breaking and its restoration for a uniformly accelerated observer. We employ the Nambu–Jona-Lasinio model in Rindler...

Search for solar hadronic axions produced by a bremsstrahlung-like process
Abstract We have searched for hadronic axions which may be produced in the Sun by a bremsstrahlung-like process, and observed in the HPGe detector by an axioelectric effect. A conservative upper limit on the hadronic axion mass of ...

The masses of gauge fields in higher spin field theory on AdS(4)
Abstract Higher spin field theory on AdS(4) is defined by lifting the minimal conformal sigma model in three-dimensional flat space. This allows to calculate the masses from the anomalous dimensions of the currents in the sigma model. The Goldstone...

Gauge mediated supersymmetry breaking without exotics in orbifold compactification
Abstract We suggest SU(5)′ in the hidden sector toward a possible gauge mediated supersymmetry breaking scenario for removing the SUSY flavor problem, with an example constructed in Z ...

Statistical effect in the parton distribution functions of the nucleon
Abstract A new and simple statistical approach is performed to calculate the parton distribution functions (PDFs) of the nucleon in terms of light-front kinematic variables. We do not put in any extra arbitrary parameter or corrected term by hand,...

Glueball hunting in e+e−→J/ψ→φf0
Abstract Building on recent work by Brodsky et al., we advocate searching for glueball degrees of freedom in e + e −→J/ψ→φf 0 at CLEO-c and BES. ...

Generalized N=(2,2) supersymmetric non-linear sigma models
Abstract We rewrite the N=(2,2) non-linear sigma model using auxiliary spinorial superfields defining the model on T⊕ ∗ T , where ...

Phase diagram of the D3/D5 system in a magnetic field and a BKT transition
Abstract We study the full temperature and chemical potential dependence of the D3/D5 2 + 1 -dimensional theory in the presence of a magnetic field. The...

Modified gravity in Arnowitt–Deser–Misner formalism
Abstract Motivated by Hořava–Lifshitz gravity theory, we propose and investigate two kinds of modified gravity theories, the f ( R ) ...

Two-dimensional Lorentz-violating Chern–Simons-like action
Abstract We demonstrate generation of the two-dimensional Chern–Simons-like Lorentz-breaking action via an appropriate Lorentz-breaking coupling of scalar and spinor fields at zero as well as at the finite temperature and via the noncommutative...

Transverse single spin asymmetries in photon production
Abstract Transverse single spin asymmetries (SSA) in inclusive reactions are now considered to be directly related to the transverse momentum k T ...

Short distance non-perturbative effects of large distance modified gravity
Abstract In a model of large distance modified gravity we compare the non-perturbative Schwarzschild solution of [G. Gabadadze, A. Iglesias, Phys. Rev. D 72 (2005) 084024, hep-th/0407049] to approximate solutions obtained previously. In the regions...

Daemon decay and inflation
Abstract Quantum tunneling in Reissner–Nordström geometry is studied and the tunneling rate is determined. A possible scenario for cosmic inflation, followed by reheating phases and subsequent radiation-domination expansion, is proposed. ...

Realistic two-nucleon potentials for the relativistic two-nucleon Schrödinger equation
Abstract The potentials V (v) in the nonrelativistic (relativistic) nucleon–nucleon (NN) Schrödinger equation are related by a quadratic equation. That equation is numerically solved, thus providing phase equivalent v-potentials related for instance ...
