The dynamic of a charged quantum particle in a system of arrays of quantum well in tight-binding model, under the effect an external field, in one and two dimension, is studied by algebraic approach. The persistent‎ (quantum confinement) and ‎transmission ‎(quantum teleportaion) probabilities of this quantum particle in terms of infinite-variable Bessel functions is calculated and the results i...

A model for composite elementary Standard Model (SM) particles based upon magnetically bound vorton pairs, briefly introduced here, predicts the existence of a complete family of magnetically charged particles, as well as their neutral isotopic partners (all counterparts to the SM elementary particles), in which the lowest mass (charged) particle would be an electrically neutral stable lepton, ...

A search for long-lived charged massive particles in CDF's Run1b data sample is presented. The search looks for highly ionizing tracks which would result from slowly moving massive particles. We search for strongly produced particles using a stable color triplet quark as a reference model, and a separate search was performed for weakly produced particles using long-lived sleptons in GaugeMediat...

Abstract. SciBooNE is a neutrino experiment measuring neutrino cross sections on carbon in the one GeV region. We have performed a search for charged current coherent pion production from muon neutrinos scattering on carbon, νμ 12C → μ−12Cπ+. No evidence for coherent pion production is observed. We set 90% confidence level upper limits on the cross section ratio of charged current coherent pion...

A discrete version of the Charged System Search algorithm (CSS) is developed to optimize truss structures with discrete variables. The discrete CSS algorithm, similar to its original version, is based on some laws from electrostatics and the Newtonian mechanics. Each agent in the CSS is considered as a charged sphere having a uniform volume charge density which can affect an electric force to t...

A search was made for relativistic qnarks of charge e/3 in cosmic-ray showers at sea level. A hodoscope of wire proportional counters was used, which was capable of measuring location and specific ionization of several particles arriving simultaneously, An upper limit for the Qux of quarks observed singly in the apparatus was established, with 90% confidence, at 1.9x10 ~ sec cm sr . Correspondi...

Charged-lepton flavor-violating processes are unobservable in the standard model, but they are predicted to be enhanced in several extensions to the standard model, including supersymmetry and models with leptoquarks or compositeness. We present a search for such processes in a sample of 99x10(6)Upsilon(2S) decays and 117x10(6)Upsilon(3S) decays collected with the BABAR detector. We place upper...
