Frequency dependence of electrical conductivity and dielectric constant of UO2
Abstract The dielectric constant and electrical conductivity of single crystal and polycrystalline UO2 are found to be frequency dependent. The dielectric constant measured at low frequencies is anomalously large at room temperature but decreases to ...

Short-range force between two Higgs bosons
Abstract The S-wave scattering length and the effective range of the Higgs boson in Standard Model are studied using effective-field-theory approach. After incorporating the first-order electroweak correction, the short-range force between two Higgs ...

Signatures of quantum gravity in a Born–Oppenheimer context
Abstract We solve a general equation describing the lowest order corrections arising from quantum gravitational effects to the spectrum of cosmological fluctuations. The spectra of scalar and tensor perturbations are calculated to first order in the ...

Path-integral invariants in abelian Chern–Simons theory
Abstract We consider the U ( 1 ) Chern–Simons gauge theory defined in a general closed oriented 3-manifold M; the functional...

Superluminal noncommutative photons
Abstract With the help of the Seiberg–Witten map, one can obtain an effective action of a deformed QED from a noncommutative QED. Starting from the deformed QED, we investigate the propagation of photons in the background of electromagnetic field,...

Low-temperature measurement of the giant dipole resonance width
Abstract The width of the giant dipole resonance (GDR) built on excited states was determined from a measurement of γ-decays in coincidence with 17O particles scattered inelastically from 120Sn. The bombarding energy was 80 MeV/u. A width of...

Instanton contribution to the proton and neutron electric form factors
Abstract We study the instanton contribution to the proton and neutron electric form factors. Using the single instanton approximation, we perform the calculations in a mixed time-momentum representation in order to obtain the form factors directly...

Two-dimensional gravity with an invariant energy scale
Abstract We investigate the gauging of a two-dimensional deformation of the Poincaré algebra, which accounts for the existence of an invariant energy scale. The model describes 2D dilaton gravity with torsion. We obtain explicit solutions of the...

Singlet-to-triplet ratio in the deuteron breakup reaction pd→pnp at 585 MeV
Abstract Available experimental data on the exclusive pd→pnp reaction at 585 MeV show a narrow peak in the proton–neutron final-state interaction region. It was supposed previously, on the basis of a phenomenological analysis of the shape of this...

Comparing lattice Dirac operators in smooth instanton backgrounds
Abstract We compare the behavior of different lattice Dirac operators in gauge backgrounds which are lattice discretizations of a classical instanton. In particular, we analyze the standard Wilson operator, a chirally improved Dirac operator and the ...

Degrees of freedom and the deconfining phase transition
Abstract There is a sharp increase in the relative number of degrees of freedom at the deconfining phase transition. Characterizing this increase using the Polyakov Loop model, we find that for three colors, where there is a nearly second order...

Understanding the SNO+ Detector
Abstract SNO+, a large liquid scintillator experiment, is the successor of the Sudbury Neutrino Observatory (SNO) experiment. The scintillator volume will be loaded with large quantities of 130Te, an isotope that undergoes double beta decay, in...

Some consequences of the Majoron being the dark radiation
Abstract We discuss some phenomenological consequences in a scenario where a singlet Majoron plays the role of dark radiation. We study the interrelations between neutrino mass generation and the scalar potential arising from this identification. We ...
