Double-tag events in two-photon collisions at LEP
Abstract Double-tag events in two-photon collisions are studied using the L3 detector at LEP centre-of-mass energies from s =189 GeV to 209 GeV. The cross sections of the...

Search for electron decay mode e→γ+ν with prototype of Borexino detector
Abstract The prototype of the Borexino detector Counting Test Facility, located in the Gran-Sasso laboratory, has been used to obtain a bound on the stability of the electron. The new lower limit on the mean lifetime defined on 32.1 days of data set ...

Heavy-flavour production in ALICE at the LHC
Abstract ALICE at the LHC is the experiment dedicated to study the physics of nucleus-nucleus collisions. The apparatus is well suited for the measurement of heavy-quark hadron production, making use of the high spatial resolution provided by the...

Spectral and spatial variations of the diffuse γ-ray background in the vicinity of the Galactic plane and possible nature of the feature at 130 GeV
Abstract We study the properties of the diffuse γ-ray background around the Galactic plane at energies 20–200 GeV. We find that the spectrum of this emission possesses significant spacial variations with respect to the average smooth component. The...

Using Trust to Establish Cooperative Spectrum Sensing Framework
Abstract Cooperative spectrum sensing in cognitive radio networks need many users to carry out because sensing performace is influenced by the credibility of a single user. A trsut based cooperative spectrum sensing framework is put forward for...

Apparent superluminal neutrino propagation caused by nonlinear coherent interactions in matter
Abstract Quantum coherence can significantly increase the strength of the forward scattering of neutrinos propagating through the Earth and interacting with matter. The index of refraction of the neutrinos propagating in a medium and hence their...

Exclusive production of pseudoscalar mesons in neutrino–photon interactions
Abstract Exclusive production of the π mesons in neutrino–photon interactions at low momentum transfer is studied within the standard model. The corresponding cross sections are calculated analytically. Potential astrophysical implications and the...

Norm-overlap formula for Hartree–Fock–Bogoliubov states with odd number parity
Abstract A formula to calculate the norm overlap between Hartree–Fock–Bogoliubov (HFB) states with odd number parity (one quasi-particle excited states) is derived with the help of Grassmann numbers and Fermion coherent states. The final formula is...

A comment on the emission from the Galactic Center as seen by the Fermi telescope
Abstract In the recent paper of Hooper and Goodenough (2010) [10] it was reported that γ-ray emission from the Galactic Center region contains an excess compared to the contributions from the large-scale diffuse emission and known point sources....

Information theory, model error, and predictive skill of stochastic models for complex nonlinear systems
Abstract Many problems in complex dynamical systems involve metastable regimes despite nearly Gaussian statistics with underlying dynamics that is very different from the more familiar flows of molecular dynamics. There is significant theoretical...

The toroidal Hausdorff dimension of 2d Euclidean quantum gravity
Abstract The lengths of shortest non-contractible loops are studied numerically in 2d Euclidean quantum gravity on a torus coupled to conformal field theories with central charge less than one. We find that the distribution of these geodesic lengths ...
