Can galactic halos be made of baryons?
(Elsevier, 1983-06-23)
Several arguments are presented indicating that the apparently non-luminous matter forming massive halos of spiral galaxies is not baryonic. There are difficulties with a halo dominated by gas, snowballs, dust and rocks, ...
The possibility of a (c, s) vector current and D-->K*l[nu]
(Elsevier, 1977-09-26)
The properties of the K* and charged lepton from the charmed particle decay D-->K*l[nu] are used to give some model-independent tests for the presence of a purely vector (c, s) weak current. Present data on the electron ...
Thermal conductivity of Tl2Ba2Ca2Cu3O10 ceramics from 300 K down to 0.1 K
(Elsevier, 1991-06-15)
Thermal conductivity, [varkappa], of two ceramic samples of Tl2Ba2Ca2Cu3O10 has been measured over a temperature range from 300 K down to 0.1 K. At high temperatures, the data show features similar to the thermal conductivity ...
Measurement of the inclusive KSO branching fraction in [tau] decay
(Elsevier, 1988-04-28)
The inclusive production of KSO mesons [tau] lepton decay has been studied using the high resolution spectrometer at the PEP e+e- storage ring operated at [radical sign]s=29 GeV. The data sample corresponds to an integrated ...
Letter: Schwarzschild Atmospheric Processes: A Classical Path to the Quantum
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-04)
We develop some classical descriptions for processes in the Schwarzschild string atmosphere. These processes suggest relationships between macroscopic and microscopic scales. The classical descriptions developed in this ...
Growth of resistance with density of scatterers in one dimensional wave propagation
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1986-11)
We study wave propagation in a one-dimensional disordered array of scattering potentials. We consider three different ensembles of scatterer configurations: an N -ensemble with a fixed number N of scatterers, an L -ensemble ...
Relaxation time and effective mass of ions in liquid helium
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1970-03)
A measurement of momentum relaxation times for charged particles in liquid helium is reported. The method is to measure the change in the reflection coefficient of a microwave cavity caused by the admission of ions. The ...
Two-particle cluster integral in the expansion of the dielectric constant
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1982-08)
We study in detail the two-particle cluster integral in the cluster expansion for the effective dielectric constant of a suspension of spherically symmetric polarizable inclusions embedded in a uniform medium. Although our ...
Search for heavy sequential neutrinos at PEP and PETRA
(Elsevier, 1984-01-26)
The experimental signature of the production of heavy, sequential neutrinos at the PEP and PETRA e+e- colliders is discussed. The model for this discussion assumes that in analogy with quarks the neutrino mass spectrum ...
On the definition of the weak mixing angle
(Elsevier, 1990-03-22)
A discussion of the need for a definition of sin2[theta] is presented. The use of a minimal subtraction scheme is advocated.
