The mercedes-benz approach to [gamma]-ray astronomy
(Elsevier, 1988-02-01)
The sensitivity requirements for ground-based [gamma]-ray astronomy are reviewed in the light of the most reliable estimates of stellar fluxes above 100 GeV. Current data strongly favor the construction of detectors with ...
The central drift chamber for the high resolution spectrometer at PEP
(Elsevier, 1982-12-01)
The central drift chamger of the High Resolution Spectrometer (HRS) at PEP is described. Results on efficiency, calibrations and resolution are given for magnetic fields up to 1.6 T.
Beyond the standard model
(Elsevier, 1989-06)
This conference emphasizes (in part) rare decays and symmetries. My talk examines possible ways to get at physics beyond the standard model from the perspective of rare decays, CP violation, and the collider frontier.
Test results from a uranium hadron calorimeter using wire chamber readout
(Elsevier, 1987-03-01)
A uranium gas sampling calorimeter has been tested with electrons and pions between 1 and 50 GeV. A comparative evaluation of the response and the resolution for proportional and streamer mode operation of the gas wire ...
Alpha-particle emission from contaminants in counter materials
(Elsevier, 1987-04-01)
Energy spectra of surface activities from thorium and uranium contaminants have been investigated for typical counter materials. Soft-tempered stainless steel with a rate of 1.2 +/- 0.1 [alpha]-particles emitted per 100 ...
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 ...
Speculations on a strongly interacting Higgs sector
(Elsevier, 1984-11-05)
Using the 1/N expansion, we argue that the O2N Higgs-Goldstone model may be a good indicator of the behavior of the standard SU2 [circle times operator] U1 electroweak model in the non-perturbative limit of a strongly ...
A new renormalization group approach to multiscale problems
(Elsevier, 1984-02-27)
A new renormalization group is presented which exploits invariance with respect to more than one scale. The method is illustrated by a simple model, and future applications to fields such as critical phenomena and supersymmetry ...
Thin-film cryogenic accelerator targets
(Elsevier, 1982-12-01)
Thin-film accelerator targets (0.1 mg/cm2 x 2) produced by condensation of various gases (Ar, Kr, Xe, N2, etc.) onto thin, cryogenically cooled substrates (T = 20 K to 80 K) have been developed and tested in-beam with 35 MeV 4He.
Scale fixing by dimensional transmutation: Supersymmetric unified models and the renormalization group
(Elsevier, 1983-01-10)
We show how the renormalization group may be used in supersymmetric models to determine the expectation values of fields whose scales are undetermined by the classical potential. We apply this formalism to supersymmetric ...
