Nuclear Science and Data Needs for Advanced Nuclear Systems
Abstract Nuclear data are of fundamental importance in studies of nuclear technology such as the design of fission power plants, fusion devices and accelerators. The large amounts of data required are stored in computer readable formats in data...

A two scale model of air corona discharges
Abstract This paper deals with the modelling of plasma discharges induced by electrohydrodynamic actuators. We propose a multi-model method based on fluid conservation equations that allows an increase of the maximum time step imposed by usual...

A comment on the self-tuning of cosmological constant with deficit angle on a sphere
Abstract In the 6D brane world model with a 4-form flux on a sphere S 2 for self-tuning the cosmological constant, we comment on the fine-tuning problem in view of the quantization of the dual 2-form flux and the orbifolding...

The chiral magnetic effect in hydrodynamical approach
Abstract We consider a model with two conserved currents, vector and axial, and two associated chemical potentials, μ and μ 5 ...

When D-branes break
Abstract We analyze the possible configurations of D-branes breaking on other D-branes. We describe these configurations in the context of a brane–antibrane effective theory in two ways. First as a tachyon configuration representing a non-trivial...

Summing over all topologies in CDT string field theory
Abstract By explicitly allowing for topology to change as a function of time, two-dimensional quantum gravity defined through causal dynamical triangulations gives rise to a new continuum string field theory. Within a matrix-model formulation we...

Spectroscopic factors of cluster decays in an algebraic cluster model
Abstract We propose a new ansatz for the cluster spectroscopic factor in an algebraic cluster model. The parameters of the ansatz are fitted to the experimental and Blendowske–Walliser values of the spectroscopic factor for light emitted clusters...

Small scale structure formation in chameleon cosmology
Abstract Chameleon fields are scalar fields whose mass depends on the ambient matter density. We investigate the effects of these fields on the growth of density perturbations on sub-galactic scales and the formation of the first dark matter halos....

How does fusion hindrance show up in medium-light systems? The case of 48Ca+48Ca
Abstract The fusion excitation function of 48Ca+ 48Ca has been measured above and well below the Coulomb barrier, thereby largely extending the energy range of a previous experiment down to very low cross sections. This system...

The Standard Model Higgs boson as the inflaton
Abstract We argue that the Higgs boson of the Standard Model can lead to inflation and produce cosmological perturbations in accordance with observations. An essential requirement is the non-minimal coupling of the Higgs scalar field to gravity; no...

Nonlocal condensate model for QCD sum rules
Abstract We include effects of nonlocal quark condensates into QCD sum rules (QSR) via the Källén–Lehmann representation for a dressed fermion propagator, in which a negative spectral density function manifests their nonperturbative nature. Applying ...

Testing non-standard CP violation in neutrino propagation
Abstract Non-standard physics which can be described by effective four fermion interactions may be an additional source of CP violation in the neutrino propagation. We discuss the detectability of such a CP violation at a neutrino factory. We assume ...

Photon pair production at flavour factories with per mille accuracy

Could dark energy be measured in the lab?
Abstract The experimentally measured spectral density of current noise in Josephson junctions provides direct evidence for the existence of zero-point fluctuations. Assuming that the total vacuum energy associated with these fluctuations cannot...

An extra push from entrance-channel effects
Abstract Symmetric heavy-ion collisions are known to display an ‘extra-push’ effect. That is, the energy at which the s-wave transmission is 0.5 lies significantly higher than the nominal Coulomb barrier. Despite this, however, the capture cross...

The role of domain wall junctions in Carter's pentahedral model
Abstract The role of domain wall junctions in Carter's pentahedral model is investigated both analytically and numerically. We perform, for the first time, field theory simulations of such model with various initial conditions. We confirm that there ...

Reheating temperature and the right-handed neutrino mass
Abstract We discuss the reheating temperature in the instant preheating scenario. In this scenario, at the last stage of inflation, the inflaton field first decays into another scalar field with an enormous number density via the instant preheating...

Is cosmic parity violation responsible for the anomalies in the WMAP data?
Abstract In this Letter, I argue that a parity violating extension to general relativity can simultaneously explain the observed loss in power and provides a first step for explaining the alignment at a preferred axis (‘Axis of Evil’) in the low...
