Spontaneous symmetry breaking in quasi-super-renormalizable models
(Elsevier, 1987)
By studying the effective potential and renormalization group for quasi-super-renormalizable models it is demonstrated the models can undergo spontaneous symmetry breaking in a manner consistent with stability. A relation ...
Symmetry tests with highly charged ions
(Elsevier, 1989-09-02)
We summarize the present status of testing the standard model of parity nonconservation in neutral atoms, emphasizing the success in understanding the semileptonic weak interactions. There is good agreement for the nuclear ...
Bismuth germanate scintillator as a fast high-energy ion detector
(Elsevier, 1984-08-01)
The pulse-height response and timing characteristics of bismuth germanate scintillator haven been determined for light and heavy ions (A [les] 35 E [les] 250 MeV). Timing resolutions of [les] 250 ps have been observed.
Conformal symmetry, unitarity, and the equations of motion for strings in background fields
(Elsevier, 1989-05-15)
We impose the constraint of the unitarity of the S-matrix on the theory of a closed bosonic string propagating in a background of some of its modes. The equations of motion for not only the massless but also for some of ...
Perhaps scalar neutrinos are the lightest supersymmetric partners
(Elsevier, 1984-07-23)
We consider the possibility that the scalar partners of the neutrinos are the least massive supersymmetric partners, and show that this alternative is compatible with cosmological constraints, which put a significant lower ...
Parton spin asymmetries in polarized hadrons at high energies
(Elsevier, 1986-09-22)
The predictions of perturbative QCD for the evolution of quark and gluon distributions for polarized hadrons, in general, and for polarized protons, in particular, are developed. Analytical and numerical studies suggest ...
Observations on horizontal symmetries and flavor changing neutral currents
(Elsevier, 1982-04-26)
We present a detailed study of the possibility of having a horizontal gauge symmetry, in addition to SU(3)c x SU(2)L x U(1). Grand unification is not used as a constraint. We concentrate on the horizontal group SU(3)H. ...
