Efficient algorithms for estimating the width of nearly normal distributions
(Elsevier, 1983-06-15)
Typical physics data samples often conform to Gaussian distributions with admixtures of more slowly varying backgrounds. Under such circumstances the standard deviation is known to be a poor statistical measure of distribution ...
Cross sections for dark matter particles and implications for allowed masses, interactions, and detection
(Elsevier, 1986)
We present scattering and annihilation cross sections for a number of candidates for dark matter: heavy neutrinos, photinos, scalar-neutrinos, and higgsinos. In the mass region below about 10 GeV, annihilation cross sections ...
The 12C([alpha], n)15O and 16O([alpha], n)19Ne reactions at E[alpha] = 41 MeV
(Elsevier, 1981-06-15)
Spectra and neutron angular distributions have been obtained for the ([alpha], n) reaction on 12C and 16O to (a) determine whether with this reaction more detailed spectroscopic information can be extracted than from ...
Heavy particles and the [varrho] parameter in the standard model
(Elsevier, 1981-11-09)
A new formalism is presented for the calculation of the contribution [delta][varrho] to [varrho] = Mw2/Mz2cos2[theta]w from heavy particles transforming according to arbitrary representations of SU(2) x U(1). A conjecture ...
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) ...
Annular reflectors for an FEL resonator
(Elsevier, 1986-09-01)
A resonator configuration suitable for a high-power, annular-mode FEL is discussed. The resonator is a four-element linear resonator with grazing-incidence reflectors. Cylindrically symmetric, paraboloid grazing incidence ...
Total internal reflection fluorescence in biological systems
(Elsevier, 1984-12)
Fluorescence of labeled proteins near a solid/liquid interface can be excited by the evanescent field of total internal reflection to study reversible adsorption kinetics and surface diffusion.
Decoupling in theories with anomalies
(Elsevier, 1981-11-02)
We consider the appearance of infinities due to the triangle anomaly in the Weinberg model by introducing terms in the lagrangian which restore the Ward identities. It is then shown that these are not the same as the ...
Gammatrica
(Elsevier, 1989-06-12)
Equations for strings and traces of strings of [gamma] matrices are summarized.
