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, ...
Production cross section and electroweak asymmetry of D* and D mesons produced in e+e- annihilations at 29 GeV
(Elsevier, 1988-05-26)
The production of D* and D mesons has been studied in e+e- annihilations at [radical sign]s=29 GeV. The data, corresponding to an integrated luminosity of 300 pb-1, were obtained using the HRS detector at PEP. The cross ...
On algebraic models of dynamical systems
(Kluwer Academic Publishers; D. Reidel Publishing Company ; Springer Science+Business Media, 1982-03)
We describe a universal algebraic model which, being read appropriately, yields (periodic and infinite) discrete dynamical systems, as well as their ‘continuous limits’, which cover all differential scalar Lax systems. For ...
Noncompact N=2 supergravity
(Elsevier, 1984-02-09)
A massive spin-one multiplet with central charge is coupled to N=2 supergravity. Compared to conventional gauge fields the anomalous magnetic moment of the spin-one particles is of the opposite sign. The construction of ...
Light-assisted transport of nitric oxide across membranes containing nitrosyl chloride solutions
(Elsevier, 1986-04)
Experimental evidence for the light-assisted concentration of nitric oxide taking part in a reversible photochemical reaction in a solution is presented. For the system, nitrosyl chloride-nitric oxide, a gradient of light ...
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 ...
The geometrical hierarchy model and N = 1 supergravity
(Elsevier, 1983-06-02)
We incorporate the geometrical hierarchy model of Dimopoulos and Raby into N = 1 supergravity. Supersymmetry is spontaneously broken at a scale of order 1011 GeV and the cosmological constant is fine tuned to zero. A grand ...
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 ...
Inclusive [eta] production in [tau] decays
(Elsevier, 1987-10-22)
We have searched for inclusive [eta] production in [tau] decays using a data sample of 2553 events of e+e- -->[tau]+[tau]- in the one-three topology. The data were obtained using the High Resolution Spectrometer at ...
