Euclidean nonlinear classical field equations with unique vacuum
(Springer-Verlag, 1978-10)
We study the real, Euclidean, classical field equation 0$$]]> where φ: ℝ d →ℝ is suitably small at infinity. We study existence and regularity assuming that λ≧0, F ∈ C ∞ (ℝ), and aF ( a )≧0∀ a ∈∝. These hypotheses allow ...
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 ...
Interplay between perturbative and non-perturbative effects in the stealthy Higgs model
(Springer-Verlag; Springer-Verlag Berlin Heidelberg / Società Italiana di Fisica, 2001-05)
We study corrections to electroweak precision variables in a model with strongly interacting singlet Higgs particles.
Could the quark electroweak and mass eigenstates coincide?
(Elsevier, 1987-10-15)
We conjecture that in the absence of new mixing effects at the weak scale the standard quark mass eigenstates and the quark weak eigenstates would coincide, and that for all three families a simple hierarchy would apply, ...
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 ...
Neutron total cross sections on protons and nuclei in the 10 to 30 GeV/c momentum range
(Elsevier, 1971-10-04)
We present the results of a recent AGS measurement of the total cross section for neutrons on protons, deuterons and other nuclei in the momentum range 10 to 30 GeV/c. The standard good-geometry transmission technique was ...
Implications of the [tau] and b spins for theories of quarks and leptons
(Elsevier, 1980-01-14)
We argue that the present evidence that the spin of the [tau] is 1/2 is circumstantial, and that a spin of 3/2 is not excluded. If the [tau] spin were 3/2, it would have important implications for the idea that leptons and ...
Note on the Fried-Yennie gauge
(Elsevier, 1980-09)
It is pointed out that the renormalization constants and the finite parts of the self energy and the vertex corrections in the infrared-free Fried-Yennie gauge are different, by finite amounts, from those which are computed ...
Enhanced and quenched Raman scattering by interface phonons in semiconductor superlattices: What are the defects?
(Elsevier, 1988)
We report on the magnetic field and power density dependences of resonant Raman scattering by interface phonons in GaAs---AlxGa1-xAs superlattices. Strong photoexcitation leads to quenching of the nominally forbidden (and ...
