Search for Fractionally Charged Particles in Showers of Low Density
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...
متن کاملLocalization of fractionally charged quasi-particles.
An outstanding question pertaining to the microscopic properties of the fractional quantum Hall effect is understanding the nature of the particles that participate in the localization but that do not contribute to electronic transport. By using a scanning single electron transistor, we imaged the individual localized states in the fractional quantum Hall regime and determined the charge of the...
متن کاملNonlinear Resonance Benchmarking Experiment at the CERN Proton Synchrotron
As a first step of a space charge nonlinear resonance benchmarking experiment over a large number of turns, beam loss and emittance evolution were measured over 1 s on a 1.4 GeV kinetic energy flat-bottom in the presence of a single octupole. By lowering the working point towards the resonance a gradual transition from a loss-free core emittance blow-up to a regime dominated by continuous loss ...
متن کاملDilepton Radiation at the CERN Super Proton Synchrotron
A quantitative evaluation of dilepton sources in heavy-ion reactions is performed taking into account both thermal and non-thermal production mechanisms. The hadronic thermal emission rate is based on an electromagnetic current-correlation function with a low-mass region (LMR, M . 1 GeV) dominated by vector mesons (ρ, ω, φ) and an intermediate-mass region (IMR, 1 GeV ≤ M ≤ 3 GeV) characterized ...
متن کاملA Search for Charged Massive Stable Particles
standard model. The hypothetical particles are assumed to be pair-produced in pp̄ collisions giving a signature of two reconstructed muon-like objects with high invariant mass and time-offlights indicative of heavy particles. Since no excess over background is observed, cross-section limits for the pair-production of stable staus and charginos are set. Mass limits of 140 GeV for a higgsino-like ...
