Granite, a new very high energy gamma-ray telescope
(Elsevier, 1990-03)
A international collaboration of astrophysicists plan to construct a new 10-meter diameter gamma-ray Cerenkov telescope at the Whipple Observatory on Mt. Hopkins in Arizona. By operatin in coincidence with the original ...
Curvature and flatness in a Brans-Dicke universe
(Elsevier, 1994-06-27)
The evolution of a universe with Brans-Dicke gravity and nonzero curvature is investigated here. We find solutions to the equations of motion during the radiation dominated era. In a Friedman-Robertson-Walker cosmology we ...
Decay angular distributions of p[pi]- states formed in diffraction dissociation of neutrons on carbon
(Elsevier, 1972-08-01)
We present decay angular distributions of the p[pi]- system formed from the interactions of 25-30 GeV/c neutrons on a carbon target. The data are studied as afunction of t', which allows a partial separation of coherent ...
The performance of "Virtual Phase" CCDs as detectors of minimum-ionizing particles
(Elsevier, 1987-10-01)
The Texas Instruments "Virtual Phase" CCD has been the basis of an ambitious design for a precision vertex detector to be used at the Stanford Linear Collider. The performance of this chip shows promise for future use in ...
Implications of a Higgs interpretation of the [zeta](8.3)
(Elsevier, 1985)
We consider the implications if the new state seen by the Crystal Ball collaboration in radiative [Upsilon]-decay, the [zeta](8.3), is interpreted as a Higgs boson. We show that BR([zeta]-->gg)<0.06 or [zeta](8.3) ...
On the bare pomeron graph in two-dimensional QCD
(Elsevier, 1977-10-03)
We present a detailed study of the bare pomeron graph in two-dimensional QCD in the 1/Nc approximation. The absence of a new singularity unrelated to quark parameters is derived. The "cylinder" graph is shown to induce ...
Photobleaching with a subnanosecond laser flash
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1994-06)
In standard fluorescence recovery after photobleaching (FRAP) applications for measuring lateral diffusion rates and adsorption/desorption kinetics of fluorescent molecules at biological or model membranes, irreversible ...
Coulomb displacement energies in the shell
(Elsevier, 1968-06-24)
The experimental Coulomb displacement energies in the shell (except one) can be described by Hecht's Coulomb energy equation with a standard deviation of 8.5 keV if it is assumed that the Coulomb interaction radius is ...
On the bound states of the massless free field in two space-time dimensions
(Elsevier, 1976-12-06)
We point out the peculiar kinematics of zero-mass fields in two space-time dimensions by showing that the n-fold tensor product of one-particle representations of the Poincare group for n [ges] 2 contains a countable ...
A description of drift chambers used in a Fermilab experiment
(Elsevier, 1976-11-01)
We give a detailed description of the drift chamber system used in a charm search at Fermilab. All important aspects of design and performance are discussed.
