Antiproton proton annihilations at 1.6-2.2 GeV/c into final states with a K1o meson
(Elsevier, 1972-06-01)
Antiproton proton annihilations into final states containing at least one K1o meson have been studied in a 150 000 picture bubble chamber experiment. The experiment covered six incident antiproton momenta in the range ...
An X-ray size-temperature relation for galaxy clusters: Observation and simulation
(Univ Chicago Press, 1997-12-10)
We show that galaxy clusters conform to a tight relation between X-ray isophotal size R-I and emission-weighted intracluster medium (ICM) temperature [T-X]. The best-fit relation for 41 members of an X-ray flux-limited ...
A Comparison of Cosmological Hydrodynamic Codes
(Univ Chicago Press, 1994-07-20)
We present a detailed comparison of the simulation results of various cosmological hydrodynamic codes. Starting with identical initial conditions based on the cold dark matter scenario for the growth of structure, with ...
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 ...
Response of high resolution drift tubes to relativistic heavy ions
(Elsevier, 1985-11-15)
We report the results of various tests undertaken in a program to develop a drift tube hodoscope for a cosmic ray balloon experiment intended to search for extragalactic antimatter. Included are studies of mechanical ...
Virialization in N-Body Models of the Expanding Universe: 2. All Pairs
(Univ Chicago Press, 1985)
Hagedorn inflation of D-branes
(IOP Publishing Ltd, 2001-01-01)
We examine the cosmological effects of the Hagedorn phase in models where the observable universe is pictured as a D-brane. It is shown that, even in the absence of a cosmological constant, winding modes cause a negative ...
Optical Signatures of High-Redshift Galaxy Clusters
(Univ Chicago Press, 1994-03-20)
We combine an N-body and gasdynamic simulation of structure formation with an updated population synthesis code to explore the expected optical characteristics of a high-redshift cluster of galaxies. We examine a poor (2 ...
Observational tests of open strings in braneworld scenarios
(IOP Publishing Ltd, 2003-07-01)
We consider some consequences of describing the gauge and matter degrees of freedom in our universe by open strings, as suggested by the braneworld scenario. We focus on changes in causal structure described by the ...
