Charged-Lepton-Flavour Violation in the Light of the Super-Kamiokande Data
John Ellis, M. E. Gomez, G. K. Leontaris +2
Motivated by the data from Super-Kamiokande and elsewhere indicating oscillations of atmospheric and solar neutrinos, we study charged-lepton-flavour violation, in particular the r…
Scalar mesons as simple quark+antiquark states
Eef van Beveren, George Rupp
The Nijmegen Unitarized Meson Model and its application to scalar mesons is briefly revisited. It is shown that all scalar states up to 1.5 GeV can be described as triplet-P-zero q…
Linking solar and long baseline terrestrial neutrino experiments
E. Kh. Akhmedov, G. C. Branco, M. N. Rebelo
We show that in the framework of three light neutrino species with hierarchical masses and assuming no fine tuning between the entries of the neutrino mass matrix, one can use the…
Quantum Logic with a Single Trapped Electron
S. Mancini, A. M. Martins, P. Tombesi
We propose the use of a trapped electron to implement quantum logic operations. The fundamental controlled-NOT gate is shown to be feasible. The two quantum bits are stored in the…
Proposed astrophysical test of Lorentz invariance
O. Bertolami, C. S. Carvalho
Working in the context of a Lorentz-violating extension of the standard model we show that estimates of Lorentz symmetry violation extracted from ultra-high energy cosmic rays beyo…
A measurement of Omega from the North American test flight of BOOMERANG
A. Melchiorri, P. A. R. Ade, P. de Bernardis +22
We use the angular power spectrum of the Cosmic Microwave Background, measured during the North American test flight of the BOOMERANG experiment, to constrain the geometry of the u…
