Leptoquark Production in e−e−e^-e^- Scattering

We consider the production of scalar and vector leptoquarks in $e^-e^-$ collisions. Although this reaction is not competitive with {\em e.g.} $e^-\gamma$ scattering for discovering these heavy states, it is the main process susceptible of differentiating two important classes of leptoquarks.Comment: 9 pages, talk presented at the Santa Cruz e-e- Workshop, UCSC, 4-5 September 199

On some subgroups of linear groups over F2\mathbb{F}_2 generated by elements of order 33

Let $V$ be a vector space over the field of order $2$. We investigate subgroups of the linear group $GL(V)$ which are generated by a conjugacy class $D$ of elements of order $3$ such that all $d$ in $D$ have $2$-dimensional commutator space $[V,d]$

The geometry of hyperbolic lines in polar spaces

In this paper we consider partial linear spaces induced on the point set of a polar space, but with as lines the hyperbolic lines of this polar space. We give some geometric characterizations of these and related spaces. The results have applications in group theory, in the theory of Lie algebras and in graph theory

Selectron Searches in e−e−e^-e^- Scattering

We review the pair-production and decay of selectrons in $e^-e^-$ collisions and show how the standard model backgrounds can be virtually eliminated with polarized beams. The exceedingly simple analysis involved and the large sample of background-free supersymmetric events make this linear collider operating mode ideal for discovering selectrons and measuring the mass of the lightest neutralino.Comment: 6 pages, talk presented at the Santa Cruz e-e- Workshop, UCSC, 4-5 September 199

Model-Independent Z′Z' Limits from Electron-Electron Collisions

Model independent constraints on the mass of an extra neutral gauge boson and its couplings to charged leptons are given for the $e^-e^-$ option of a future linear collider. Analytic exclusion limits are derived in the Born approximation. The results are compared with those of the $e^+e^-$ mode. The influence of radiative corrections is discussed.Comment: 7 pages, LaTeX, 4 Figures, uuencoded Postscriptfile, MPI-Ph/94-23, LMU-04/9
