Higgs–dilaton(radion) system confronting the LHC Higgs data
Abstract We consider the Higgs–dilaton(radion) system using the trace of energy–momentum tensor ( T ...

The Radiation of Internal Waves by a Turbulent Fountain in a Stratified Fluid
Abstract The objective of the present paper is to study by large-eddy simulation (LES) the dynamics of a fountain created by a turbu-lent vertical jet flow penetrating a pycnocline (a sharp density interface) in a density-stratified fluid. A...

Highlights from CMS
Abstract The CMS collaboration has used a data set of 1 billion PbPb collisions at the LHC to study the behavior of strongly interacting matter at high temperature. In this Paper, we present selected recent highlights from this effort, with a...

Higher twist corrections to the sum rule for semileptonic B decay
Abstract The sum rule for charmless inclusive semileptonic B-meson decays allows a theoretically clean and experimentally efficient determination of |V ub |. The leading twist...

Low x scattering as a critical phenomenon
Abstract We discuss deep inelastic scattering at low x as a critical phenomenon in 2+1 spacetime dimensions. QCD (SU(2)) near the light cone becomes a critical theory in the limit of limx→0 with a correlation mass m(x)∝x ...

Gamma-ray Measurements with LaBr3: Ce Detectors -thinking Outside the Box
Abstract Recently developed cerium-doped lanthanum bromide (LaBr3: Ce) scintillation detectors have shown to possess promising properties with respect to the detection of γ-rays compared to previously known materials. In this work however, we...

On the stability of gravity in the presence of a non-minimally coupled scalar field
Abstract We show that Einstein's gravity coupled to a non-minimally coupled scalar field is stable even for high values of the scalar field, when the sign of the Einstein–Hilbert action is reversed. We also discuss inflationary solutions and a...

Gravi-burst: super-GZK cosmic rays from localized gravity
Abstract The flux of cosmic rays beyond the GZK cutoff (∼1020 eV) may be explained through their production by ultra high energy cosmic neutrinos, annihilating on the relic neutrino background, in the vicinity of our galaxy. This process, known as...

Warped and compact extra dimensions: 5D branes in 6D models
Abstract We consider six-dimensional brane world models with a compact and a warped extra dimension with five-dimensional branes. We find that such scenarios have many interesting features arising from both ADD and Randall–Sundrum models. In...

Fragmentation production of Ωccc and Ωbbb baryons
Abstract The Λ baryons with a single heavy flavor which transfer the quark polarization, have been studied both theoretically and experimentally. The Ξ's with two heavy constituents are well treated in quark–diquark model. In this work we study the...

On the estimation of nuclear level density parameters in the region of some large deformed nuclei
Abstract In this Letter the nuclear level density is discussed in terms of collective excitation modes. The level density parameters due to different excitation bands of observed nuclear spectra in the region of a large deformed even–even, odd–odd...

Quark number susceptibilities from HTL-resummed thermodynamics
Abstract We compute analytically the diagonal quark number susceptibilities for a quark–gluon plasma at finite temperature and zero chemical potential, and compare with recent lattice results. The calculation uses the approximately self-consistent...

Supersymmetry of identical bands in 171,172Yb supported by lifetime data
Abstract Precision lifetimes of six states in the ground-state bands of 171Yb have been measured using the recoil distance method following Coulomb excitation with a detector of the Euroball Cluster type at the FN-Tandem accelerator in Cologne. From ...

Diffractive Ds production in charged current DIS
Abstract We present a perturbative QCD calculation of diffractive D s production in charged current deep inelastic scattering. In the two-gluon exchange model, we analyze the...

Bridging two ways of describing final-state interactions in A(e,e′p) reactions
Abstract We outline a relativistic and unfactorized framework to treat the final-state interactions in quasielastic A(e,e′p) reactions for four-momentum transfers Q 2≳0.3 (GeV/c)2. The model, which relies on the eikonal...

Dipole coefficients in B→Xsγ in supersymmetry with large tanβ and explicit CP violation

The handbag contribution to γγ→ππ and KK
Abstract We investigate the soft handbag contribution to two-photon annihilation into pion or kaon pairs at large energy and momentum transfer. The amplitude is expressed as a hard γγ→q q ̄ ...

Brane-bulk interaction in topological theory
Abstract In this Letter we address the problem of inducing boundary degrees of freedom from a bulk theory whose action contains higher-derivative corrections. As a model example we consider topological theory with an action that has only a...

Past and Present Experiments of Geoneutrinos
Abstract Geoneutrinos are antineutrinos produced in radioactive decays within Earth's interior. Those antineutrinos can be detected by inverse β-decays of protons, however, due to extremely small cross section, there were no feasible experiments for ...
