Electron-positron pair production in the external electromagnetic field of colliding relativistic heavy ions
A. Aste, G. Baur, K. Hencken +2
The results concerning the production in peripheral highly relativistic heavy-ion collisions presented in a recent paper by Baltz {\em{et al.}} are rederived in a very str…
Oxygen Isotope Effect of the Plane-Copper NQR Frequency in YBa_2Cu_4O_8
M. Mali, J. Roos, H. Keller +2
We report on high-precision measurements of the temperature dependence of the plane-^63Cu NQR line frequency nu_Q(Cu2) and the linewidth in normal and superconducting ^16O and ^18O…
Scattering of light exotic atoms in excited states
T. S. Jensen, V. E. Markushin
The differential and total cross sections for the scattering of muonic, pionic, kaonic and antiprotonic hydrogen in excited states from atomic hydrogen have been calculated for the…
Temperature and field dependence of the anisotropy of MgB2
M. Angst, R. Puzniak, A. Wisniewski +5
The anisotropy gamma of the superconducting state of high quality single-crystals of MgB2 was determined, using torque magnetometry with two different methods. The anisotropy of th…
Dark matter and gamma rays from the galactic halo
Philippe Jetzer
The nature of the dark matter in the halo of our Galaxy is still largely unknown. The microlensing events found so far towards the Large Magellanic Cloud suggest that at most about…
Counting contact terms in decays
Alexander Khodjamirian, Daniel Wyler
We clarify the origin and cancellation of contact terms in the weak annihilation amplitudes contributing to . It is demonstrated that the photon emission from the final-s…
A Purity Monitoring System for the H1 Liquid Argon Calorimeter
H1 Calorimeter Group, E. Barrelet
The ionization probes used for monitoring the liquid argon purity in the H1 calorimeter are described and results of their operation in tests at CERN and during the period 1992 to…
Electric field gradients from first-principles and point-ion calculations
E. P. Stoll, P. F. Meier, T. A. Claxton
Point-ion models have been extensively used to determine "hole numbers" at copper and oxygen sites in high-temperature superconducting cuprate compounds from measured nuclear quadr…
^25Mg NMR study of the MgB_2 superconductor
M. Mali, J. Roos, A. Shengelaya +2
^25Mg NMR spectra and nuclear spin-lattice relaxation time, T_1, have been measured in polycrystalline ^25MgB_2 with a superconducting transition temperature T_c = 39.0 K in zero m…
The attainable superconducting Tc in a model of phase coherence by percolation
D. Mihailovic, V. V. Kabanov, K. A. Muller
The onset of macroscopic phase coherence in superconducting cuprates is considered to be determined by random percolation between mesoscopic Jahn-Teller pairs, stripes or clusters.…
Microlensing by Compact Objects associated to Gas Clouds
V. Bozza, Ph. Jetzer, L. Mancini +1
We investigate gravitational microlensing of point-like lenses surrounded by diffuse gas clouds. Besides gravitational bending, one must also consider refraction and absorption phe…
On the Globalization of Kontsevich's Star Product and the Perturbative Poisson Sigma Model
Alberto S. Cattaneo, Giovanni Felder
The globalization of Kontsevich's local formula (resp., the perturbative expansion of the Poisson sigma model) is described in down-to-earth terms.
Chiral perturbation theory, dispersion relations and final state interactions in K -> pi pi
Gilberto Colangelo
We discuss the recent literature on the treatment of final state interactions in K -> pi pi. Various approaches are compared and particular emphasis is given to the possibility of…
Microlensing search towards M31
S. Calchi Novati, G. Iovane, A. A. Marino +26
We present the first results of the analysis of data collected during the 1998-99 observational campaign at the 1.3 meter McGraw-Hill Telescope, towards the Andromeda galaxy (M31),…
Search for Excited Neutrinos at HERA
H1 Collaboration, C. Adloff
We present a search for excited neutrinos using e^-p data taken by the H1 experiment at HERA at a center-of-mass energy of 318 GeV with an integrated luminosity of 15 pb-1. No evid…
Schroedinger discovery of wave mechanics
Norbert Straumann
Schroedinger's great discovery of wave mechanics in 1926 - his annus mirabilis - is discussed in detail. Beside the six most important papers that appeared during the first half of…
Tidal debris of dwarf spheroidals as a probe of structure formation models
Lucio Mayer, Ben Moore, Thomas Quinn +2
Recent observations suggest that Carina and other nearby dwarf spheroidal galaxies are surrounded by unbound stars tidally stripped by the Milky Way. We run high-resolution N-Body…
Evidence for three dimensional superconductivity in the cuprates oxides
T. Schneider
We review the empirical scenario emerging from the measured doping dependence of the transition temperature and the anisotropy parameter , defined as the ratio…
Improved Analysis of B->pi e nu from QCD Sum Rules on the Light-Cone
Patricia Ball, Roman Zwicky
We present a new calculation of the B->pi form-factor f_+, relevant for the measurement of |V_{ub}| from semileptonic B->pi transitions, from QCD sum rules on the light-cone. The n…
Electroweak-correction effects in gauge-boson pair production at the LHC
Elena Accomando, Ansgar Denner, Stefano Pozzorini
We have studied the effect of one-loop logarithmic electroweak radiative corrections on WZ and production processes at the LHC. We present analytical results for the leading-l…
