Defining 〈A2〉 in the finite volume Hamiltonian formalism
Abstract It is shown how in principle for non-Abelian gauge theories it is possible in the finite volume Hamiltonian framework to make sense of calculating the expectation value of ‖A‖2=∫d3x(Aa i( x ...

Precursors from S(1)/Z2×Z2′ orbifold GUTs
Abstract The possibility of appearance of GUT precursors near the TeV scale (suggested by Dienes–Dudas–Gherghetta) is addressed within 5D GUTs compactified on an S (1)/Z 2×Z 2′ orbifold. ...

Discrete light-cone quantization on a twisted torus
Abstract Recently it has been demonstrated by Dienes and Mafi that the physics of toroidal compactified models of extra dimensions can depend on the shape angle of the torus. Toroidal compactification has also recently been used as a regulator for...

Two loop MS renormalization of the Curci–Ferrari model
Abstract We renormalize the Curci–Ferrari model at two loops in the MS scheme in an arbitrary covariant gauge.

Newton's law in braneworlds with an infinite extra dimension
Abstract We study the behavior of the four-dimensional Newton's law in warped braneworlds. The setup considered here is a (3+n)-brane embedded in 5+n dimensions, where n extra dimensions are compactified and a dimension is infinite. We show that the ...

Alpha decay of 114Ba
Abstract The neutron-deficient isotope 114Ba was produced through the 58Ni( 58 Ni,2n) reaction, separated as a 114 Ba 19 ...

High-precision ϵ-expansions of three-loop master integrals contributing to the electron g–2 in QED
Abstract In this Letter we calculate at high-precision the Laurent expansions in ϵ=(4−D)/2 of the 17 master integrals which appeared in the analytical calculation of 3-loop QED contribution to the electron g–2, using difference and differential...

p,q-Duality and Hamiltonian flows in the space of integrable systems or integrable systems as canonical transforms of the free ones
Abstract Variation of coupling constants of integrable system can be considered as canonical transformation or, infinitesimally, a Hamiltonian flow in the space of such systems. Any function T( p ...

First observation of excited structures in neutron-deficient 179Hg: evidence for multiple shape coexistence
Abstract Excited structures in the neutron-deficient nucleus 179Hg have been established for the first time using the Gammasphere spectrometer in conjunction with the fragment mass analyzer. Competing states originating from three different minima...

Weak magnetism effects in the direct Urca processes in cooling neutron stars
Abstract In the mean field approximation, we study the effects of weak magnetism and pseudoscalar interaction in the neutrino energy losses caused by the direct Urca processes on relativistic nucleons in the degenerate baryon matter. Our formula for ...

Higher-dimensional supersymmetry as an origin of the three families for quarks and leptons
Abstract In a (0,1) supersymmetric (SUSY) six-dimensional gauge theory, a gauge fermion gives rise to box anomalies. These anomalies are completely canceled by assuming a vector multiplet of (1,1) SUSY. With a ...

Formation and relaxation energies of electronic holes in LaMnO3 crystal
Abstract We use the Mott–Littleton approach to evaluate the electronic and ionic polarisation energies in LaMnO3 lattice associated with holes localised on both Mn3+ cation and O2− anion. The full lattice relaxation energy for a hole localised at...

Space Dust Impacts Detector Development for the Evaluation of Ejecta
Abstract This paper aims at a) introducing the space dust impacts detector developed at Kyushu Institute of Technology (KIT), b) presenting the detector utility for the evaluation of ejecta, and c) raising awareness of the space community regarding...

An interlacing approach for bounding the sum of Laplacian eigenvalues of graphs
Abstract We apply eigenvalue interlacing techniques for obtaining lower and upper bounds for the sums of Laplacian eigenvalues of graphs, and characterize equality. This leads to generalizations of, and variations on theorems by Grone, and Grone...

Overview of results on flow and correlations from the CMS collaboration
Abstract Highlights of the results obtained by the CMS experiment at the LHC on collective flow and dihadron correlations in PbPb collisions are presented. At lower transverse momenta of the outgoing particles and for a wide range of collision...

The cosmic-ray positron excess from a local Dark Matter over-density
Abstract We show that the cosmic-ray positron excess measured by PAMELA and AMS could be induced by Dark Matter annihilations in a local over-density. In such a context leptophilic DM is not needed and good fits to positron data, in agreement with...

Axion dark matter and Planck favor non-minimal couplings to gravity
Abstract Constraints on inflationary scenarios and isocurvature perturbations have excluded the simplest and most generic models of dark matter based on QCD axions. Considering non-minimal kinetic couplings of scalar fields to gravity substantially...

Parallel universe, dark matter and invisible Higgs decays
Abstract The existence of the dark matter with amount about five times the ordinary matter is now well established experimentally. There are now many candidates for this dark matter. However, dark matter could be just like the ordinary matter in a...
