Measurement of upper limits for the decay widths of D*+ and D*0
(Elsevier, 1988-10-06)
Upper limits for the decay widths of the D*+ and D*0 mesons have been measured using data from e+e- annihilations at [radical sign]s=29 GeV obtained with the High Resolution Spectrometer at PEP. We find [Gamma]D*+ c2 at ...
Energy conditions in non-Riemannian spacetimes
(Elsevier, 1994-12-26)
We interpret the energy conditions in non-Riemannian spacetimes by applying them to a family of stationary, axially symmetric solutions for the gravitational field equations for an Einstein-Cartan theory in a Riemann-Cartan ...
Measurement of the lifetime of hadrons containing the b-quark
(Elsevier, 1987-09-03)
Data collected with the High Resolution Spectrometer at PEP, corresponding to an integrated luminosity of 200 pb-1 of e+e- annihilation at 29 GeV, were used to measure the mean lifetime of hadrons containing the bottom ...
LETTER: The Life and Times of Extremal Black Holes
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2000-11)
Charged extremal black holes cannot fully evaporate through the Hawking effect and are thus long lived. Over their lifetimes, these black holes take part in a variety of astrophysical processes, including many that lead ...
Search for B-decay to Higgs bosons for Higgs boson masses between 50 and 210 MeV/c2
(Elsevier, 1989-10-05)
We use data from the Mark II experiment at PEP to search for the process B-->h0X for mh0 between 50 and 210 MeV/c2. No evidence for the Higgs boson is seen in this mass range. The limit obtained rules out the standard ...
Nonlinear stationary waves and solitary waves in fluid systems with long-range forces
(Elsevier, 1993-11-15)
We study a class of nonlinear model equations which represent one-dimensional fluid systems with long range forces (such as gravity). We present elementary theorems which constrain the allowed types of stationary wave and ...
New limits on D0 (1.865) production in proton-nucleus collisions at 400 GeV/c
(Elsevier, 1977-11-21)
We present final results of a sensitive search for new particles in [pi]+/-K[mnplus] effective mass spectra observed in proton-nucleus collisions at 400 GeV/c. We establish a limit for D0 (1.865) production B[pi]+[pi]- ...
Production properties of low-mass systems in pp collisions at 102 GeV/c
(Elsevier, 1974-10-28)
We examine in detail the properties of low-mass systems produced in the inclusive reaction p + p --> p + anything at 102 GeV/c. We find that the internal characteristics of these low-mass nucleon-multipion systems (the ...
Charm quark production and fragmentation in e+e- annihilation at 29 GeV
(Elsevier, 1984-10-11)
The electroweak production asymmetry and the decay fragmentation function for have been measured at using charged D* production over the full kinematic range. The data were taken at PEP using the High Resolution Spectrometer. ...
Search for heavy neutral leptons in e+e- annihilations at 29 GeV
(Elsevier, 1984-12-27)
A search was made in 29 GeV e+e- annihilations for heavy, neutral leptons decaying to e+/-X[mnplus]([nu]), where X is a muon or charged meson. Six events with isolated e+/-X[mnplus] pairs were found for an intergrated ...
