Vector-like fermion and standard Higgs production at hadron colliders
(Elsevier, 1990-04-09)
Vector-like fermions are characterized by large neutral current decay rates, in particular into Higgs bosons. If they exist, their clear signals at hadron colliders open a window to Higgs detection, especially to the ...
Jet production by a gluon source in QCD
(Elsevier, 1978-12-25)
The properties of jets produced by a gluon source are examined in QCD. We give a simple derivation of the jet opening angle (up to an undetermined constant) using arguments of general applicability. At asymptotic energies, ...
Raman longitudinal acoustic mode (LAM) studies of folded-chain morphology in poly(ethylene oxide) (PEO). I. Normal mode analysis of LAM of a helical-chain oligomer of PEO
(John Wiley & Sons, Inc., 1990-01-15)
Normal mode analyses were done for the exact structures of model oligomers of PEO to investigate the longitudinal acoustic mode (LAM) in this helical polymer. It quickly became apparent that it is impossible to reproduce ...
An examination of the cyanide derivative of bovine superoxide dismutase with electron-nuclear double resonance
(Elsevier, 1982-05-21)
The Cu(II) sites of native, azido- and cyano-derivatives of bovine superoxide dismutase (superoxide:superoxide oxidoreductase, EC 1.15.1.1) have been examined by electron-nuclear double resonance ENDOR). The ENDOR spectrum ...
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 ...
12C(7Li, t)16O and stellar helium fusion
(Elsevier, 1978-07-31)
The reaction 12C(7Li, t)16O has been studied at E(7Li) = 34 MeV with the LASL tandem accelerator and QDDD magnetic spectrometer. Angular distributions to levels with Ex J[pi] = 1- levels, which are of great importance in ...
Vibrational analysis of crystalline diketopiperazine--II. Normal mode calculations
(Elsevier, 1984)
Based on our Raman and i.r. [1] data and assignments for DKP and five of its isotopic derivatives, we have refined an intramolecular force field in a non-redundant basis. This analysis shows that the cis peptide group may ...
Multiple frequency EPR studies on three forms of oxidized cytochrome c oxidase
(Elsevier, 1983-10-17)
Bovine heart mitochondrial cytochrome c oxidase (cytochrome aa3) (EC 1.9.3.1) has been demonstrated to occur in several forms when the redox centers in the protein are thought to be fully oxidized. We report here the results ...
