Are there really any AdS2 branes in the Euclidean (or not) AdS3?
Abstract We do not find any AdS 2 branes, neither in the H 3 + WZNW model nor in the SL(2,R) WZNW model. We then reexamine the case of the branes that possess a su(2) symmetry: we...

On the symplectic two-form of gravity in terms of Dirac eigenvalues
Abstract The Dirac eigenvalues form a subset of observables of the Euclidean gravity. The symplectic two-form in the covariant phase space could be expressed, in principle, in terms of the Dirac eigenvalues. We discuss the existence of the formal...

The wavelength of neutrino and neutral kaon oscillations
Abstract Neutral kaons, and probably also neutrinos, exhibit oscillations between flavor eigenstates, as a result of being produced in a superposition of mass eigenstates. Several recent papers have addressed the question of the energies and momenta ...

On the day–night effect and CC to NC event rate ratio predictions for the SNO detector
Abstract Detailed predictions for the DN asymmetry for the Super-Kamiokande experiment, as well as for the full night and core DN asymmetries in the solar neutrino induced CC event rate and the day and night ratios of the CC and NC event rates,...

Bisimulation and Hidden Algebra
Abstract A hidden algebra is a special case of coalgebra. A hidden congruence on a hidden algebra corresponds to a bisimulation equivalence on the corresponding coalgebra. The paper generalizes the notion of hidden congruence to that of hidden...

Lorentz invariant CPT violation: Particle and antiparticle mass splitting
Abstract The interpretation of neutrino oscillation data has led to the question whether, in principle, an antiparticle like antineutrino can have a different mass than its particle. In the framework of a Lorentz invariant CPT violation, which is...

Estimating Air Shower Fluctuations from the Monte Carlo Simulation Code CORSIKA
Abstract The study of cosmic ray extensive air showers (EAS) offers a unique way to estimate hadronic interaction cross-section at energies beyond the reach of accelerator experiments. Usually the hadron-air cross-section is estimated either by...

Graviton resonances on two-field thick branes
Abstract This work presents new results about the graviton massive spectrum in two-field thick branes. Analyzing the massive spectra with a relative probability method we have firstly showed the presence of resonance structures and obtained a...

Higgs boson creation in laser-boosted lepton collisions
Abstract Electroweak processes in high-energy lepton collisions are considered in a situation where the incident center-of-mass energy lies below the reaction threshold, but is boosted to the required level by subsequent laser acceleration. Within...

Anomalous quark chromomagnetic moment and single-spin asymmetries
Abstract We discuss a nonperturbative mechanism for the single-spin asymmetries in the strong interaction. This mechanism is based on the existence of a large anomalous quark chromomagnetic moment induced by the nontrivial topological structure of...

Even-odd Effects of Fragment Yields in Low Energy Fission
Abstract Since the discovery of fission even-odd staggering of proton, neutron and mass yields of the fragments and their energies has been a topic of ongoing research. In the present survey only low energy fission is covered, i.e. spontaneous...

Integrable scalar cosmologies
Abstract The question whether the integrable one-field cosmologies classified in a previous paper by Fré, Sagnotti and Sorin can be embedded as consistent one-field truncations into Extended Gauged Supergravity or in N ...

Nonlinear stability of flock solutions in second-order swarming models
Abstract In this paper we consider interacting particle systems which are frequently used to model collective behaviour in animal swarms and other applications. We study the stability of orientationally aligned formations called flock solutions, one ...
