A systematic study of the low energy effects of heavy particles in the standard model
(Elsevier, 1989-11-06)
In this approach, at any loop order, the low energy effects of a heavy Higgs boson and a heavy fermion can be summarized by an effective lagrangian. To the one-loop order, an effective lagrangian for the bosonic sector of ...
Recombination kinetics in low dimensions
(Elsevier, 1988-02)
Computer simulations predict very anomalous delayed luminescence delayed luminescence decays for low-dimensional materials. Classical kinetics theory fails because excitons, electrons and holes have no convection. The mode ...
Neutrino-counting process and its major background (e+e- --> e+e-[gamma]) at the Z0 resonance
(Elsevier, 1989-01-09)
The differential and the total cross sections for the neutrino-counting process and its major source of background, radiative Bhabha scattering (e+e- --> e+e-[gamma]), are calculated for some experimentally relevant ...
Fermions in a time-periodic SU(2) background: The eigenfunctions
(Elsevier, 1987)
Isospinor fermions are studied in the presence of a covariantly constant, time-periodic SU(2) background field. The eigenfunction spectrum is derived. Part of the modes, termed transverse, decouple from the external field. ...
Speculations on a strongly interacting Higgs sector
(Elsevier, 1984-11-05)
Using the 1/N expansion, we argue that the O2N Higgs-Goldstone model may be a good indicator of the behavior of the standard SU2 [circle times operator] U1 electroweak model in the non-perturbative limit of a strongly ...
Dimethyl ether as a drift-chamber gas
(Elsevier, 1986-10-15)
We have continued the testing of dimethyl ether as a drift-chamber gas in order to improve the understanding of its properties. In particular, we report on measurement accuracy, on systematic effects, and some preliminary ...
A new renormalization group approach to multiscale problems
(Elsevier, 1984-02-27)
A new renormalization group is presented which exploits invariance with respect to more than one scale. The method is illustrated by a simple model, and future applications to fields such as critical phenomena and supersymmetry ...
Heavy flavor resonances and QED radiative corrections
(Elsevier, 1989-06-26)
We discuss QED radiative corrections applied to narrow resonances in e+e- annihilation. We establish a simple and precise prescription for extracting radiative corrections from experimental data. This prescription differs ...
Electron spectra of heavy-fermion systems
(Elsevier, 1988-12-02)
An overview is presented of current understanding and recent approaches and issues in studies of the single-particle electron spectra of heavy-fermion materials, with emphasis on uranium compounds.
