Mean-field description of ground-state properties of drip-line nuclei: Pairing and continuum effects

J. Dobaczewski, W. Nazarewicz, T. R. Werner +3

Ground-state properties of exotic even-even nuclei with extreme neutron-to-proton ratios are described in the framework of the self-consistent mean-field theory with pairing formul…

Updated: Higgs Mass Bounds Separate Models of Electroweak Symmetry Breaking

Marco A. Diaz, Tonnis A. ter Veldhuis, Thomas J. Weiler

Vacuum stability and metastability imply lower limits on the mass of the higgs boson in the Standard Model (SM). In contrast, we present an improved calculation of an upper limit o…

Constraining $α_{s} (M_{Z})$ from the Hidden Sector

Paul H. Frampton, Bettina Keszthelyi, Brian D. Wright +1

By including the effects of superstring thresholds, we reconsider minimal string unification together with the requirement of producing a supersymmetry-breaking gluino condensate i…

Coupled-barrier diffusion: the case of oxygen in silicon

Madhavan Ramamoorthy, Sokrates T. Pantelides

Oxygen migration in silicon corresponds to an apparently simple jump between neighboring bridge sites. Yet, extensive theoretical calculations have so far produced conflicting resu…

The Two-Nucleon Potential from Chiral Lagrangians

C. Ordonez, L. Ray, U. van Kolck

Chiral symmetry is consistently implemented in the two-nucleon problem at low-energy through the general effective chiral lagrangian. The potential is obtained up to a certain orde…

Measurement of the Average $B$ -Hadron Lifetime in $Z^{0}$ Decays

The SLD Collaboration

We report a measurement of the average $B$ -hadron lifetime using data collected with the SLD detector at the SLC in 1993. An inclusive analysis selected three-dimensional vertices…

Cosmological Models of Gamma-Ray Bursts

Charles D. Dermer, Thomas J. Weiler

We review models of cosmological gamma-ray bursts (GRBs). The statistical and $γ$ -ray transparency issues are summarized. Neutron-star and black-hole merger scenarios are described…

Observation of a Narrow State Decaying into $Ξ_{c}^{+} π^{-}$

CLEO Collaboration, P. Avery et al

Using data recorded by the CLEO-II detector at CESR, we report the first observation of a narrow state decaying into $Ξ_{c}^{+} π^{-}$ . The state has mass difference $M(Ξ_c^+π^-)-M(Ξ_c^+)…

Measurements of the Ratios $B (D_{s}^{+} \to η ℓ^{+} ν) / B (D_{s}^{+} \to ϕ ℓ^{+} ν)$ and $B (D_{s}^{+} \to η^{'} ℓ^{+} ν) / B (D_{s}^{+} \to ϕ ℓ^{+} ν)$

CLEO Collaboration, G. Brandenburg et al

Using the CLEO~II detector we measure $B (D_{s}^{+} \to η e^{+} ν) / B (D_{s}^{+} \to ϕ e^{+} ν) = 1.24 \pm 0.12 \pm 0.15$ , ${\cal B}(D_s^+\to η' e^+ν)/{\cal B}(D_s^+\to ϕe^+ν) =0.43\pm0.11\pm0…

Observation of the $Ξ_{c}^{+}$ Charmed Baryon Decays to $Σ^{+} K^{-} π^{+}$ , $Σ^{+} K ˉ^{* 0}$ , and $Λ K^{-} π^{+} π^{+}$

CLEO Collaboration, T. Bergfeld et al

We have observed two new decay modes of the charmed baryon $Ξ_{c}^{+}$ into $Σ^{+} K^{-} π^{+}$ and $Σ^{+} K ˉ^{* 0}$ using data collected with the CLEO II detector. We also present the firs…

Observation of the Isospin-Violating Decay $D_{s}^{*+} \to D_{s}^{+} π^{0}$

CLEO Collaboration, J. Gronberg et al

Using data collected with the CLEO~II detector, we have observed the isospin-violating decay $D_{s}^{*+} \to D_{s}^{+} π^{0}$ . The decay rate for this mode, relative to the dominant radiativ…

Magnetic Monopoles as the Highest Energy Cosmic Ray Primaries

Thomas W. Kephart, Thomas J. Weiler

We suggest that the highest energy $ \gsim 10^{20} eV$ cosmic ray primaries may be relativistic magnetic monopoles. Motivations for this hypothesis are that conventional primaries…

Consistent Treatment of Propagator Modifications in Elastic Nucleon-Nucleus Scattering within the Spectator Expansion

C. R. Chinn, Ch. Elster, R. M. Thaler +1

The theory of the elastic scattering of a nucleon from a nucleus is presented in the form of a Spectator Expansion of the optical potential. Particular attention is paid to the tre…

Topological Incarnations of Electroweak Defects

Thomas W. Kephart, Tanmay Vachaspati

We propose a criterion to classify hybrid defects occurring in field theoretic models such as the standard electroweak model. This criterion leads us to consider the minimal extens…

On the Informativeness of the DNA Promoter Sequences Domain Theory

J. Ortega

The DNA promoter sequences domain theory and database have become popular for testing systems that integrate empirical and analytical learning. This note reports a simple change an…

Energy Density of Non-Minimally Coupled Scalar Field Cosmologies

David Hochberg, Thomas W. Kephart

Scalar fields coupled to gravity via $ξ R Φ^{2}$ in arbitrary Friedmann-Robertson-Walker backgrounds can be represented by an effective flat space field theory. We derive an expressio…

Radiative Corrections to Charged Higgs Production in e+ e- Colliders

Marco A. Diaz, Tonnis A. ter Veldhuis

We study one loop electroweak corrections to the production of a pair of charged Higgs bosons through an intermediate $Z$ -boson or photon. In particular, we consider the effects of…

A Search for Jet Handedness in Hadronic $Z^{0}$ Decays

K. Abe

We have searched for signatures of polarization in hadronic jets from $Z^{0} \to q q ˉ$ decays using the ``jet handedness'' method. The polar angle asymmetry induced by the high…
