Surface acoustic wave induced magnetoresistance oscillations in a 2D electron gas
John P. Robinson, Malcolm P. Kennett, Nigel R. Cooper +1
We study the geometrical commensurability oscillations imposed onto the resistivity of 2D electrons in a perpendicular magnetic field by a propagating surface acoustic wave (SAW).…
The ppbar -> tbH^+/- Process at the Tevatron in HERWIG and PYTHIA Simulations
Johan Alwall, Catherine Biscarat, Stefano Moretti +2
Charged Higgs boson production in association with a top quark could be the first indication of the existence of Higgs particles. The Tevatron Run-II started data-taking in April 2…
New type of -periodic magneto-oscillations in a two-dimensional electron system induced by microwave irradiation
I. V. Kukushkin, M. Yu. Akimov, J. H. Smet +4
We observe a new type of magneto-oscillations in the photovoltage and the longitudinal resistance of a two-dimensional electron system. The oscillations are induced by microwave ir…
Theoretical uncertainties on alpha_s from event-shape variables in e+e- annihilations
Roger W. L. Jones, Matthew Ford, Gavin P. Salam +2
The precision of measurements of the strong coupling constant using event-shape variables in e+e- annihilations is limited by theoretical systematic uncertainties. The uncertaintie…
Characteristic Angular Scales in Cosmic Microwave Background Radiation
F. Ghasemi, A. Bahraminasab, M. Sadegh Movahed +3
We investigate the stochasticity in temperature fluctuations in the cosmic microwave background (CMB) radiation data from {\it Wilkinson Microwave Anisotropy Probe}. We show that t…
Autoparallel orbits in Kerr Brans-Dicke spacetimes
H. Cebeci, T. Dereli, R. W. Tucker
The bounded orbital motion of a massive spinless test particle in the background of a Kerr Brans-Dicke geometry is analysed in terms of worldlines that are auto-parallels of differ…
