xF-dependence of J/Ψ suppression in pA collisions
Abstract Coherence effects are important in the description of collisions with extended objects as nuclei. At fixed target energies and small x F , the coherence length of the...

The use of X-ray CT to measure diffusion coefficients of heavy ions in water-saturated porous media
Abstract X-ray computerized tomography (CT) was applied for the first time to the measurement of diffusion coefficients of heavy ions in water-saturated clay and rock. The mass absorption coefficient of X-rays is high for heavy elements. Thus the...

A Novel Imaging Algorithm for Airborne Bistatic Squint SAR with Unparallel Trajectories
Abstract A novel analytical imaging algorithm is proposed for the strip-map mode of airborne bistatic squint SAR with unparallel trajectories. The algorithm derives the two-dimensional (2D) spectrum formula of the point target echo by using the...

On quantum deformation of conformal symmetry: gauge dependence via field redefinitions
Abstract The effective action in gauge theories is known to depend on a choice of gauge fixing conditions. This dependence is such that any change of gauge conditions is equivalent to a field redefinition in the effective action. In this sense, the...

The anapole moment of the deuteron with the Argonne v18 nucleon–nucleon interaction model
Abstract We calculate the nuclear part of the deuteron anapole moment with the wave functions obtained from the Argonne v18 nucleon–nucleon interaction model. The anapole moment operators are considered at the leading order. To minimize the...

Primordial helium production in a charged universe
Abstract We use the constraints arising from primordial nucleosynthesis to bound a putative electric charge density |e|n q of the universe. We find |n ...

Hadrons as signature of black hole production at the LHC
Abstract In models with several large extra dimensions and fundamental Planck scale of the order of 1 TeV, black holes can be produced in large numbers at LHC energies. We compute the charged hadron spectra obtained from the decay of black holes...

Logarithmic correction to Newton potential in Randall–Sundrum scenario
Abstract Using a fixed-energy amplitude in Randall–Sundrum single brane scenario, we compute the Newton potential on the brane. It is shown that the correction terms to the Newton potential involve a logarithmic factor. Especially, when the distance ...

Super daisy resummations and an effective expansion parameter in the O(N)-model near the phase transition
Abstract The temperature induced phase transition in the N-component scalar field theory is investigated within the approach combining the second Legendre transform with the consideration of the gap equations in the extrema of the free energy...

A non-resonant dark-side solution to the solar neutrino problem
Abstract We reanalyse spin–flavour precession solutions to the solar neutrino problem in the light of the recent SNO CC result as well as the 1258-day Super-Kamiokande data and the upper limit on solar anti-neutrinos. In a self-consistent...

The moduli space of CP1 stringy cosmic lumps
Abstract We examine the low-energy dynamics of CP 1 lumps coupled to gravity, taking into account the gravitational back-reaction of the spacetime geometry. We show that the...

Gauge theories, D-branes and holography
Abstract Based on a generalization of the string theoretic concept of D-brane probe, we propose a new approach to large N gauge theories which makes the holographic properties manifest. For any gauge theory, we define from first principles an...

Novel T-Violation observable open to any pair of decay channels at meson factories
Abstract Quantum entanglement between the two neutral mesons produced in meson factories has allowed the first indisputable direct observation of Time Reversal Violation in the time evolution of the neutral meson between the two decays. The...

Correlation functions of the half-infinite XXZ spin chain with a triangular boundary
Abstract The half-infinite XXZ spin chain with a triangular boundary is considered in the massive regime. Two integral representations of correlation functions are proposed using bosonization. Sufficient conditions such that the expressions for...

Curvaton with nonminimal derivative coupling to gravity
Abstract We show a curvaton model, in which the curvaton has a nonminimal derivative coupling to gravity. Thanks to such a coupling, we find that the scale-invariance of the perturbations can be achieved for arbitrary values of the equation-of-state ...

Thermodynamic meaning of the index of γ-entropy
Abstract We provide a thermodynamic meaning of the index of the γ-entropy, which is a non-additive information measure devised in 1970s and is less known to physics. It is intimately related to the free energy as was previously shown for the Rényi...

Fusion-fission Study at JAEA for Heavy-element Synthesis
Abstract Fission fragment mass distributions were measured in the heavy-ion induced fission using 238U target nucleus. The mass distribu- tions changed drastically with incident energy. The results are explained by a change of the ratio between...

A pseudo-differential calculus on the Heisenberg group
Abstract In this note we present a symbolic pseudo-differential calculus on the Heisenberg group. We particularise to this group our general construction [4,2,3] of pseudo-differential calculi on graded groups. The relation between the Weyl...
