First Measurement of the Ratio B(t-->Wb)/B(t-->Wq) and Associated Limit on the CKM Element Vtb
CDF Collaboration
We present the first measurement of the ratio of branching fraction R= B(t-->wb)/B(t-->Wq) from ppbar collisions at sqrt(s)=1.8 TeV. The data set corresponds to 109 pb-1 of data re…
Measurement of the Two-Jet Differential Cross Section in proton-antiproton Collisions at sqrt{s} = 1800 GeV
CDF Collaboration
A measurement is presented of the two-jet differential cross section, d^3σ/dE_T dη_1 dη_2, at center of mass energy sqrt{s} = 1800 GeV in proton-antiproton collisions. The results…
Q-ball Evolution, B-ball Baryogenesis and the f_{B} Problem
John McDonald
We consider some of the issues surrounding the formation and evolution of Q-balls in the MSSM and its extensions. The ratio of the baryon number packed into Q-balls to that outside…
A Comparison of the Momentum Spectra in Deep Inelastic Scattering with the Modified Leading Logarithmic Approximation
N H Brook, I O Skillicorn
The evolution of the logarithmic scaled energy spectra with energy scale, in the framework of the modified leading logarithmic approximation (MLLA), is investigated. The behaviour…
Search for Supersymmetric Particles in e+e- Collisions at sqrt(s) up to 202GeV and Mass Limit for the Lightest Neutralino
ALEPH Collaboration
Searches for pair production of squarks, sleptons, charginos, and neutralinos are performed with the data collected by the ALEPH detector at LEP at centre-of-mass energies from 188…
Observation of an Excess in the Search for the Standard Model Higgs Boson at ALEPH
ALEPH Collaboration
A search has been performed for the Standard Model Higgs boson in the data sample collected with the ALEPH detector at LEP, at centre-of-mass energies up to 209GeV. An excess of 3s…
Neutrino Oscillations in Extended Anti-GUT Model
C. D. Froggatt, H. B. Nielsen, Y. Takanishi
What we call the Anti-GUT model is extended a bit to include also right-handed neutrinos and thus make use of the see-saw mechanism for neutrino masses. This model consists in assi…
The unquenched Upsilon spectrum
UKQCD collaboration, L. Marcantonio, P. Boyle +3
We describe the bottomonium spectrum obtained on the UKQCD dynamical ensembles and its comparison to quenched results. We include a determination of alpha_s and m_b from the dynmai…
Non-Thermal Dark Matter, High Energy Cosmic Rays and Late-Decaying Particles From Inflationary Quantum Fluctuations
John McDonald
It has been suggested that the origin of cosmic rays above the GZK limit might be explained by the decay of particles, X, with mass of the order of 10^{12} GeV. Generation of heavy…
Search for the Supersymmetric Partner of the Top-Quark in Collisions at
CDF Collaboration
We report on a search for the supersymmetric partner of the top quark (stop) produced in events using of collisions at $\sqrt{s} = 1.8 {…
Numerical Study of dense adjoint 2-color matter
Simon Hands, Istvan Montvay, Manfred Oevers +2
We study the global symmetries of SU(2) gauge theory with N flavors of staggered fermions in the presence of a chemical potential. We motivate the special interest of the case N=1…
Search for Neutral Supersymmetric Higgs Bosons in Collisions at TeV
CDF collaboration
We present the results of a search for neutral Higgs bosons produced in association with quarks in final states with pb$…
A nonperturbative determination of cA
S. Collins, C. T. H. Davies
We describe a non-perturbative determination of using correlators containing the axial-vector and pseudoscalar currents at zero and non-zero momentum. We apply the method of…
A simple tool for assessing the completeness in apparent magnitude of magnitude-redshift samples
Stephane Rauzy
A new tool is proposed for finding out the completeness limit in apparent magnitude of a magnitude-redshift sample. The technique, closely related to the statistical test proposed…
The Structure of the Virtual Photon
Claudia Glasman
Measurements of dijet cross sections for virtual photons are presented as a function of $\xo$, the fraction of the virtual photon energy invested in the production of the dijet sys…
Flavour singlet pseudoscalar masses in N_f = 2 QCD
T. Struckmann, K. Schilling, G. Bali +8
We perform a lattice mass analysis in the flavour singlet pseudoscalar channel on the SESAM and TXL full QCD vacuum configurations, with 2 active flavours of dynamical Wilson fermi…
Jet Substructure at HERA
Claudia Glasman
Measurements of jet shapes and subjet multiplicities in photoproduction performed by ZEUS are presented and compared to leading-logarithm parton-shower Monte Carlo models. The pred…
Color Superconductivity in Compact Stars
Mark Alford, Jeffrey A. Bowers, Krishna Rajagopal
After a brief review of the phenomena expected in cold dense quark matter, color superconductivity and color-flavor locking, we sketch some implications of recent developments in o…
A search for resonance decays to antineutrino-jet in e^+p scattering at HERA
ZEUS Collaboration, J. Breitweg
A study of the antineutrino-jet mass spectrum in e^+p -> antineutrino+X events at center-of-mass energy 300 GeV has been performed with the ZEUS detector at HERA using an integrate…
Towards the application of the Maximum Entropy Method to finite temperature Upsilon Spectroscopy
M. Oevers, C. Davies, J. Shigemitsu
According to the Narnhofer Thirring Theorem interacting systems at finite temperature cannot be described by particles with a sharp dispersion law. It is therefore mandatory to dev…
Shot Noise by Quantum Scattering in Chaotic Cavities
S. Oberholzer, E. V. Sukhorukov, C. Strunk +4
We have experimentally studied shot noise of chaotic cavities defined by two quantum point contacts in series. The cavity noise is determined as 1/4*2e|I| in agreement with theory…
