The linear and nonlinear theory of circularly-polarized Alfvdn and ion-cyclotron waves in multicomponent plasmas is reviewed. It is shown that minor heavy- ion components play an important role in the dispersive properties ...

In this paper we study new-physics contributions to the top-quark decay t → bbc. We search for ways of detecting such new physics via measurements at the LHC. As top quarks are mainly produced at the LHC in tt production ...

We propose selection cuts on the LHC tt̄ production sample which should enhance the sensitivity to new physics signals in the study of the tt̄ invariant mass distribution. We show that selecting events in which the tt̄ ...

A new (non-Noetherian) symmetry transformation for the small oscillations problem is exhibited. A novel way to solve this classical problem, based on conservation laws constructed using the new symmetry, is presented. ...

Here we show that the dynamic simulation of a molecular collision can give insight into new molecular species. In this way, a new stable isomer of C 20 (IV) has been found. It is planar with pentagonal form. This isomer ...

The Lorentz-Dirac equation of motion for the electron is derived by a new method which makes tedious power series expansions unnecessary. Copyright © 1975 American Institute of Physics.
