Search for CP Violation in , and
G. Bonvicini, CLEO Collaboration
We have searched for CP-violating asymmetries in neutral charm meson decays in 13.7 fb^-1 of e^+e^- collision data at sqrt{s} = 10.6 GeV with the CLEO detector. The measured asymme…
A Biased Review of Tau Neutrino Mass Limits
J. Duboscq
After a quick review of astrophysically relevant limits, I present a summary of MeV scale tau neutrino mass limits derived from accelerator based experiments. I argue that the curr…
A 2MASS L Dwarf Companion to the Nearby K Dwarf GJ 1048
John E. Gizis, J. Davy Kirkpatrick, John C. Wilson
We report the discovery of a probable L1 companion to the nearby K2 dwarf GJ 1048 using the Two Micron All-Sky Survey (2MASS). This source, 2MASSI J0235599-233120 or GJ 1048B, has…
Optical Seeing and Infrared Atmospheric Transparency in the Upper Atacama Desert
Riccardo Giovanelli
With plans to build a large IR/optical telescope in the Atacama Desert, a site survey campaign has been underway since 1998 to characterize the optical seeing and the IR transparen…
Asymmetry in Isolated, Morphologically Normal Sa Galaxies
David A. Kornreich, Martha P. Haynes, Katherine P. Jore +1
We have examined the morphological and dynamical HI symmetry properties of a sample of moderately inclined Sa galaxies which are classified as morphologically normal. The sample ga…
Signatures of Galaxy-Cluster Interactions: Spiral Galaxy Rotation Curve Asymmetry, Shape, and Extent
Daniel A. Dale, Riccardo Giovanelli, Martha P. Haynes +2
The environmental dependencies of the characteristics of spiral galaxy rotation curves are studied in this work. We use our large, homogeneously collected sample of 510 cluster spi…
Indivisibility of electron bubbles in helium
Veit Elser
A recent proposal by Maris[1], that single electron bubbles in helium might fission into separate, particle-like entities, does not properly take into account the failure of the ad…
Lectures on the Theory of Non-leptonic B Decays
Matthias Neubert
These notes provide a pedagogical introduction to the theory of non-leptonic heavy-meson decays recently proposed by Beneke, Buchalla, Sachrajda and myself. We provide a rigorous b…
Effects from the charm scale in K+ -> pi+ nu nubar
Adam F. Falk, Adam Lewandowski, Alexey A. Petrov
We consider contributions to the rare decay K+ -> pi+ nu nubar which become nonlocal at the charm scale. Compared to the leading term, such amplitudes are suppressed by two powers…
Rectification of displacement currents in an adiabatic electron pump
P. W. Brouwer
Rectification of ac displacement currents generated by periodic variation of two independent gate voltages of a quantum dot can lead to a dc voltage linear in the frequency. The pr…
Phase Diagram for the Winfree Model of Coupled Nonlinear Oscillators
J. T. Ariaratnam, S. H. Strogatz
In 1967 Winfree proposed a mean-field model for the spontaneous synchronization of chorusing crickets, flashing fireflies, circadian pacemaker cells, or other large populations of…
On the constitution of sodium at higher densities
J. B. Neaton, N. W. Ashcroft
Using density functional theory the atomic and electronic structure of sodium are predicted to depart substantially from those expected of simple metals for 2.48 (…
Evidence of New States Decaying into
S. E. Csorna, CLEO Collaboration
Using 13.7 of data recorded by the CLEO detector at CESR, we report evidence for two new charmed baryons: one decaying into with the subsequent decay…
Neutron Star Kicks and Asymmetric Supernovae
Dong Lai
Observational advances over the last decade have left little doubt that neutron stars received a large kick velocity (of order a few hundred to a thousand km/s) at birth. The physi…
Grope cobordism of classical knots
Jim Conant, Peter Teichner
We explain the notion of a grope cobordism between two knots in a 3-manifold. Each grope cobordism has a type that can be described by a rooted unitrivalent tree. By filtering thes…
Two-Loop Renormalization of Heavy--Light Currents at Order 1/m_Q in the Heavy-Quark Expansion
Thomas Becher, Matthias Neubert, Alexey A. Petrov
We present exact results, at next-to-leading order in renormalization-group improved perturbation theory, for the Wilson coefficients appearing at order 1/m_Q in the heavy-quark ex…
Precession of Magnetically Driven Warped Disks and Low-Frequency QPOs in Low-Mass X-Ray Binaries
Akiko Shirakawa, Dong Lai
An accretion disk around a rotating magnetized star is subjected to magnetic torques which induce disk warping and precession. These torques arise from interactions between the ste…
Novel Method of Measuring Electron Positron Colliding Beam Parameters
D. Cinabro, K. Korbiak, R. Ehrlich +2
Through the simultaneous measurement of the transverse size as a function of longitudinal position, and the longitudinal distribution of luminosity, we are able to measure the $β_y…
Aircraft Hazard related to gas emission from the Earth
Thomas Gold
I think it important that pilots, the aircraft industry, air safety staff, accident investigators, should all be aware of the possibility of the hazard described in the accompanyin…
Who is the best connected scientist? A study of scientific coauthorship networks
M. E. J. Newman
Using data from computer databases of scientific papers in physics, biomedical research, and computer science, we have constructed networks of collaboration between scientists in e…
A Measurement of the Decay Asymmetry Parameters in $Ξ_{c}^{0}\to \X^{-}π^{+}$
S. Chan, CLEO Collaboration
Using the CLEO II detector at the Cornell Electron Storage Ring we have measured the decay asymmetry parameter in the decay . We find $α_{Ξ_c^{0}}…
New Value of M_mu/M_e from Muonium Hyperfine Splitting
Richard Hill
The complete contribution to the muonium hyperfine splitting of relative order alpha^3(m_e/m_mu)ln(alpha) is calculated. The result amounts to 0.013 kHZ, much smaller than suggeste…
Measurement of the Lifetime
A. H. Mahmood, CLEO Collaboration
The lifetime is measured using 9.0 fb of annihilation data collected on or just below the resonance with the CLEO II.V detector at CESR. Using a…
Sharp HI edges at high z: the gas distribution from Damped Lyman-alpha to Lyman-limit absorption systems
Edvige Corbelli, Edwin E. Salpeter, Rino Bandiera
We derive the distribution of neutral and ionized gas in high redshift clouds which are optically thick to hydrogen ionizing radiation, using published data on Lyman-limit and Damp…
