CYBERSUSY: A new mechanism for supersymmetry breaking in models like the supersymmetric standard model (SSM)
The SUSY breaking in Cybersusy is proportional to the VEV that breaks the
gauge symmetry SU(2) X U(1) down to U(1), and it is rather specific to models
like the SSM. Assuming full breaking, as explained below, for the leptons,
Cybersusy predicts a spectrum of SUSY breaking that is in accord with
experimental results so far. In particular, for the choice of parameters below,
Cybersusy predicts that the lowest mass superpartner for the charged leptons is
a charged vector boson lepton (the Velectron), which has a mass of 316 Gev .
The Selectron has a mass of 771 Gev for that choice of parameters. The theory
also leads to a zero cosmological constant after SUSY breaking. The mechanism
generates equations that restrict models like the SSM. This version of this
paper incorporates recent results and changes discovered subsequent to the
talk.Comment: This is a revision of a talk given at SUSY 2009. It incorporates an
important set of changes. 4 page
Some Properties of Chiral Dotted Spinor Superfields
Chiral superfields with multiple dotted Lorentz spinor indices (`dotspinors')
are important in the analysis of supersymmetry breaking through the mechanisms
of Cybersusy. This paper describes the actions for massive dotspinors coupled
to supersymmetric gauge theory and to chiral matter. It analyzes the free
equations of motion and mass spectra for the case of unbroken supersymmetry.
The general form of the Cybersusy algebra for dotsupers with multiple indices
is also discussed briefly.Comment: 20 page
Antenna Factorization in Strongly-Ordered Limits
When energies or angles of gluons emitted in a gauge-theory process are small
and strongly ordered, the emission factorizes in a simple way to all orders in
perturbation theory. I show how to unify the various strongly-ordered soft,
mixed soft-collinear, and collinear limits using antenna factorization
amplitudes, which are generalizations of the Catani--Seymour dipole
factorization function.Comment: 21 pages, 8 figures; final Phys Rev version, corrected definition of
multiple-emission recosnstruction functions for strongly-ordered limit, added
appendix with new form of double-emission antenna function valid in
strongly-ordered limi
Higher Spin BRS Cohomology of Supersymmetric Chiral Matter in D=4
We examine the BRS cohomology of chiral matter in , supersymmetry
to determine a general form of composite superfield operators which can suffer
from supersymmetry anomalies. Composite superfield operators \Y_{(a,b)} are
products of the elementary chiral superfields and \ov S and the
derivative operators D_\a, \ov D_{\dot \b} and \pa_{\a \dot \b}. Such
superfields \Y_{(a,b)} can be chosen to have `' symmetrized undotted
indices \a_i and `' symmetrized dotted indices \dot \b_j. The result
derived here is that each composite superfield \Y_{(a,b)} is subject to
potential supersymmetry anomalies if is an odd number, which means that
\Y_{(a,b)} is a fermionic superfield.Comment: 15 pages, CPT-TAMU-20/9
