Superspace Geometrical Representations of Extended Super Virasoro Algebras
Utilizing sets of super-vector fields (derivations), explicit expressions are
obtained for; (a.) the 1D, N-extended superconformal algebra, (b.) the 1D,
N-extended super Virasoro algebra for N = 1, 2 and 4 and (c.) a geometrical
realization (GR) covering algebra that contains the super Virasoro algebra for
arbitrary values of N. By use of such vector fileds, the super Virasoro algebra
is embedded as a geometrical and model-independent structure in 1D and 2D
Aleph-null-extended superspace.Comment: 13 pages, Late
Searching for Supersymmetry in Hadrons
We discuss the possibility of the existence of a long-lived top squark
() and its motivation. If the stop is indeed metastable,
it forms hadrons. We study properties of the low-energy stop-containing hadrons
and their signatures in collider experiments.Comment: 14 pages, 2 figure
Two Two-Dimensional Supergravity Theories from Calabi-Yau Four-Folds
We consider two-dimensional supergravity theories with four supercharges
constructed from compactification of Type II string theory on a generic
Calabi-Yau four-fold. In Type IIA and Type IIB cases, respectively, new
superspace formulations of N=(2,2) and N=(0,4) dilaton supergravities are found
and their coupling to matter multiplets is discussed.Comment: 47 pages, harvma
