Observation of enhanced orbital electron-capture nuclear decay rate in a compact medium
Abstract The eigenstate energies of an atom increase under spatial confinement and this effect should increase the electron density of the orbital electrons at the nucleus thus increasing the decay rate of an electron capturing radioactive nucleus....

Linear inflation from running kinetic term in supergravity
Abstract We propose a new class of inflation models in which the coefficient of the inflaton kinetic term rapidly changes with energy scale. This naturally occurs especially if the inflaton moves over a long distance during inflation as in the case...

Wave dynamics of a six-dimensional black hole localized on a tensional three-brane
Abstract We study the quasinormal modes and the late-time tail behavior of scalar perturbation in the background of a black hole localized on a tensional three-brane in a world with two large extra dimensions. We find that finite brane tension...

Trinification with sin2θW=3/8 and see-saw neutrino mass
Abstract We realize a supersymmetric trinification model with three families of ( 27 tri + 27 ...

On the unitarity of linearized General Relativity coupled to matter
Abstract We consider the unitarity of the S-matrix for linearized General Relativity coupled to particle physics models. Taking renormalization group effects of the Planck mass into account, we find that the scale at which unitarity is violated is...

Two-loop parameter relations between dimensional regularization and dimensional reduction applied to SUSY-QCD
Abstract The two-loop relations between the running gluino–quark–squark coupling, the gluino and the quark mass defined in dimensional regularization (DREG) and dimensional reduction (DRED) in the framework of SUSY-QCD are presented. Furthermore, we ...

Directed and elliptic flow in 197Au + 197Au at intermediate energies
Abstract Directed and elliptic flow for the 197Au + 197Au system at incident energies between 40 and 150 MeV per nucleon has been measured using the INDRA 4π multi-detector. For semi-central collisions, the elliptic flow of ...

Instanton solution in tachyon cosmology
Abstract We find an exact classical solution in Euclidean gravity coupled to a scalar field with a particular form of potential commonly used in tachyon cosmology. This solution represents a tunneling between two vacua.

Generalized modified gravity in large extra dimensions
Abstract We discuss effective interactions among brane matter induced by modifications of higher-dimensional Einstein gravity through the replacement of Einstein–Hilbert term with a generic function f ...

Tachyon-Chaplygin inflationary universe model
Abstract Tachyonic inflationary universe model in the context of a Chaplygin gas equation of state is studied. General conditions for this model to be realizable are discussed. By using an effective exponential potential we describe in great details ...

Cosmology with a variable Chaplygin gas
Abstract We consider a new generalized Chaplygin gas model that includes the original Chaplygin gas model as a special case. In such a model the generalized Chaplygin gas evolves as from dust to quiescence or phantom. We show that the background...

Suppression of supergravity anomalies in conformal sequestering
Abstract We show that the anomaly-mediated supersymmetry breaking via the Kähler and sigma-model anomalies is suppressed by conformal dynamics in the supersymmetry breaking sector.

Stability of asymmetric tetraquarks in the minimal-path linear potential
Abstract The linear potential binding a quark and an antiquark in mesons is generalized to baryons and multiquark configurations as the minimal length of flux tubes neutralizing the color, in units of the string tension. For tetraquark systems,...

Triality and Bagger–Lambert theory
Abstract We present two alternative field contents for Bagger–Lambert theory, based on the triality of SO ( 8 ) . The first content ...

Quantum information and gravity cutoff in theories with species
Abstract We show that lowering of the gravitational cutoff relative to the Planck mass, imposed by black hole physics in theories with N species, has an independent justification from quantum information theory. First, this scale marks the limiting...

Renormalization of supersymmetric gauge theories on orbifolds: Brane gauge couplings and higher derivative operators
Abstract We consider supersymmetric gauge theories coupled to hypermultiplets on five- and six-dimensional orbifolds and determine the bulk and local fixed point renormalizations of the gauge couplings. We infer from a component analysis that the...

The strangeness content of the nucleon from effective field theory and phenomenology

Fabrication, characterization and its local reflection properties of a metal-mirror microcavity with high concentrated PIC J-aggregates
Abstract We have investigated reflection properties of light-matter strong coupling in a planar metal-mirror microcavity with highly concentrated PIC J-aggregates. Large vacuum Rabi-splitting ranging from 100 to 250 meV is obtained depending on the...

Wave Guide Imaging through Time Domain Topological Energy
Abstract Time Domain Topological Energy (TDTE), uses a measure of the reflected ultrasonic field on an array of transducers placed on the boundary of the imaged medium. Two numerical determinations (direct and adjoint problems) of the acoustical...
