Quantum Group Actions on the Cuntz Algebra
The Cuntz Algebra carries in a natural way the structure of a module algebra over the quantized universal envelo** algebra U q ...

Cold Atom Clocks, Precision Oscillators and Fundamental Tests
We describe two experimental tests of the Equivalence Principle that are based on frequency measurements between precision oscillators and/or highly accurate atomic frequency standards. Based on comparisons be...

BCFW recursion relation with nonzero boundary contribution
The appearance of BCFW on-shell recursion relation has deepen our understanding of quantum field theory, especially the one with gauge boson and graviton. To be able to write the BCFW recursion relation, the k...

Open AccessCombined measurement and QCD analysis of the inclusive e ± p scattering cross sections at HERA
A combination is presented of the inclusive deep inelastic cross sections measured by the H1 and ZEUS Collaborations in neutral and charged current unpolarised e ±

Open AccessTransverse-momentum and pseudorapidity distributions of charged hadrons in pp collisions at \(\sqrt{s} = 0.9 \) and 2.36 TeV
Measurements of inclusive charged-hadron transverse-momentum and pseudorapidity distributions are presented for proton-proton collisions at ...

Open AccessEvents with an isolated lepton and missing transverse momentum and measurement of W production at HERA
A search for events containing an isolated electron or muon and missing transverse momentum produced in e ± p collisions is performed with the H1 and ZEUS detectors...

Leptogenesis as a common origin for matter and dark matter
We propose a model of asymmetric dark matter (DM) where the dark sector is an identical copy of both forces and matter of the standard model (SM) as in the mirror universe models discussed in literature. In ad...

Non-standard interactions versus non-unitary lepton flavor mixing at a neutrino factory
The impact of heavy mediators on neutrino oscillations is typically described by non-standard four-fermion interactions (NSIs) or non-unitarity (NU). We focus on leptonic dimension-six effective operators whic...

Open AccessDiffractive electroproduction of ρ and ϕ mesons at HERA
Diffractive electroproduction of ρ and ϕ mesons is measured at HERA with the H1 detector in the elastic and proton dissociative channels. The data correspond to an integrated luminosity of 51 pb−1. About 10500 ρ ...

Linear confinement for mesons and nucleons in AdS/QCD
By using a new parametrization of the dilaton field and including a cubic term in the bulk scalar potential, we realize linear confinement in both meson and nucleon sectors within the framework of soft-wall Ad...

Open AccessSearch for neutral Higgs bosons decaying into four taus at LEP2
A search for the production and non-standard decay of a Higgs boson, h, into four taus through intermediate pseudoscalars, a, is conducted on 683 pb−1 of data collected by the ALEPH experiment at centre-of-mass e...

Article
MSSM in view of PAMELA and Fermi-LAT
We take the MSSM as a complete theory of low energy phenomena, including neutrino masses and mixings. This immediately implies that the gravitino is the only possible dark matter candidate. We study the implic...

QCD-like theories at nonzero temperature and density
We investigate the properties of hot and/or dense matter in QCD-like theories with quarks in a (pseudo)real representation of the gauge group using the Nambu-Jona-Lasinio model. The gauge dynamics is modeled u...

Dual identities inside the gluon and the graviton scattering amplitudes
Recently, Bern, Carrasco and Johansson conjectured dual identities inside the gluon tree scattering amplitudes. In this paper, we use the properties of the heterotic string and open string tree scattering ampl...

Consistency conditions on S-matrix of spin 1 massless particles
Motivated by new techniques in the computation of scattering amplitudes of massless particles in four dimensions, like BCFW recursion relations, the question that how much structure of the S-matrix can be dete...

Rotation Numbers of Linear Schrödinger Equations with Almost Periodic Potentials and Phase Transmissions
In this paper we study the linear Schrödinger equation with an almost periodic potential and phase transmission. Based on the extended unique ergodic theorem by Johnson and Moser, we will show for such an equa...

Quantum gravity effects on statistics and compact star configurations
The thermodynamics of classical and quantum ideal gases based on the Generalized uncertainty principle (GUP) are investigated. At low temperatures, we calculate corrections to the energy and entropy. The equat...

Refractive index in holographic superconductors
With the probe limit, we investigate the behavior of the electric permittivity and effective magnetic permeability and related optical properties in the s-wave holographic superconductors. In particular, our r...

Seesaw type I and III at the LHeC
We study the potential of testing the seesaw type-I and III models at the Large Hadron-electron Collider (LHeC), an e-p collision mode at the CERN collider. The e-p collision mode provides an excellent place t...

Open AccessPerformance of the ATLAS detector using first collision data
More than half a million minimum-bias events of LHC collision data were collected by the ATLAS experiment in December 2009 at centre-of-mass energies of 0.9 TeV and 2.36 TeV. This paper reports on studies of t...
