Conformal gauge mediation
Abstract We propose a one-parameter theory for gauge mediation of supersymmetry (SUSY) breaking. The spectrum of SUSY particles such as squarks and sleptons in the SUSY standard-model and the dynamics of SUSY-breaking sector are, in principle,...

On quasi-normal modes of Kerr black holes
Abstract We calculate analytically asymptotic values of quasi-normal frequencies of four-dimensional Kerr black holes by solving the Teukolsky wave equation. We obtain an expression for arbitrary spin of the wave in agreement with Hod's proposal...

Statefinder diagnosis for Ricci dark energy
Abstract Statefinder diagnostic is a useful method which can differ one dark energy model from each others. In this Letter, we apply this method to a holographic dark energy model from Ricci scalar curvature, called the Ricci dark energy model...

Cosmological constraints from radial baryon acoustic oscillation measurements and observational Hubble data
Abstract We use the Radial Baryon Acoustic Oscillation (RBAO) measurements, distant type Ia supernovae (SNe Ia), the observational H ( z ) ...

AdS3/LCFT2 – Correlators in new massive gravity
Abstract We calculate 2-point correlators for New Massive Gravity at the chiral point and find that they behave precisely as those of a logarithmic conformal field theory, which is characterized in addition to the central charges ...

Resolving the instability of the Savvidy vacuum by dynamical gluon mass
Abstract In this Letter we apply the formalism of local composite operators as developed by Verschelde et al. in combination with a constant chromomagnetic field as considered in the seventies by Savvidy and others. We find that a nonzero ...

New data on tensor analyzing power Ayy of the relativistic deuteron breakup as additional test of deuteron structure at small distances
Abstract New data on the tensor analyzing power A yy of the 9 Be(d,p)X reaction at an initial deuteron momentum of 5 GeV/c and a...

Dual approaches for defects condensation
Abstract We review two methods used to approach the condensation of defects phenomenon. Analyzing in details their structure, we show that in the limit where the defects proliferate until occupy the whole space these two methods are dual equivalent...

Brane-world black hole entropy from modified dispersion relations
Abstract The entropy of the Reissner–Nördstrom black hole is studied within the context of a brane-world scenario. Such a black hole is a solution of the Einstein field equations on the brane, possessing a tidal charge which is a reflection of the...

Some properties of the Alday–Maldacena minimum
Abstract The Alday–Maldacena solution, relevant to the n = 4 gluon amplitude in N = ...

CFT adapted gauge invariant formulation of arbitrary spin fields in AdS and modified de Donder gauge
Abstract Using Poincaré parametrization of AdS space, we study totally symmetric arbitrary spin massless fields in AdS space of dimension greater than or equal to four. CFT adapted gauge invariant formulation for such fields is developed. Gauge...

Charmonium spectrum from quenched QCD with overlap fermions
Abstract We present the first study of the charmonium spectrum using overlap fermions, on quenched configurations. Simulations are performed on 16 3 ...

Neutrino clustering in growing neutrino quintessence
Abstract A growing neutrino mass can stop the dynamical evolution of a dark energy scalar field, thus explaining the “why now” problem. We show that such models lead to a substantial neutrino clustering on the scales of superclusters. Non-linear...

A more general interacting model of holographic dark energy
Abstract So far, there have been no theories or observational data that deny the presence of interaction between dark energy and dark matter. We extend naturally the holographic dark energy (HDE) model, proposed by Granda and Oliveros, in which the...

The effects of Ag, Mg, and Pr doping on the superconductivity and structure of BSCCO
Abstract The influence of Ag, Mg, and Pr additions and co-additions on microstructure and phase formation of Bi2Sr2CaCu2O8+d (Bi2212) system is investigated. Polycrystalline Bi2212 samples were synthesized in air by solid state reaction method....

Calculation of Muon Depth Distributions in Thin Film Single Crystals
Abstract To investigate the effects of sample crystallinity and the consequent channeling on the stopping distribution of low energy muons, we compare the results of the well-known binary-collision-approximation code(BCA): TRIM to results from...
