Instantaneous Bethe-Salpeter Equation: Analytic Approach for Nonvanishing Masses of the Bound-State Constituents
Wolfgang Lucha, K. Maung Maung, F. F. Schoberl
The instantaneous Bethe-Salpeter equation, derived from the general Bethe-Salpeter formalism by assuming that the involved interaction kernel is instantaneous, represents the most…
Instantaneous Bethe-Salpeter equation: utmost analytic approach
Wolfgang Lucha, Khin Maung Maung, F. F. Schoberl
The Bethe-Salpeter formalism in the instantaneous approximation for the interaction kernel entering into the Bethe-Salpeter equation represents a reasonable framework for the descr…
Gaugino Mass Dependence of Electron and Neutron Electric Dipole Moments
L. Clavelli, T. Gajdosik, W. Majerotto
Unless squarks and sleptons are in the multi-TeV region or above, CP violating induced electric dipole moments of elementary particles can pose significant puzzles for supersymmetr…
Impact of e^+ and e^- Beam Polarization on Chargino and Neutralino Production at a Linear Collider
G. Moortgat-Pick, A. Bartl, H. Fraas +1
We study the production processes e^+ e^- -> chi^+_i chi^-_j, i,j=1,2, and e^+ e^- -> chi^0_m chi^0_n, m,n=1,...,4, working out the advantages of polarizing both beams. For e^+ e^-…
Exploiting Spin Correlations in Neutralino Production and Decay with Polarized e^- and e^+ Beams
G. Moortgat-Pick, A. Bartl, H. Fraas +1
We study the production process e^+ e^- -> chi^0_1 chi^0_2 and the subsequent decay chi^0_2 -> chi^0_1 l^+ l^- with polarized e^+ and e^- beams, including the spin correlations bet…
Numerical Solution of the Spinless Salpeter Equation by a Semianalytical Matrix Method (a Mathematica 4.0 routine)
Wolfgang Lucha, F. F. Schoberl
In quantum theory, the so-called "spinless Salpeter equation," the relativistic generalization of the nonrelativistic Schroedinger equation, is used to describe both bound states o…
