Chiral SUSY Theories with a Suppressed SUSY Charge
The well-known Chiral and Gauge SUSY Actions realize the SUSY charge in terms
of transformations among the Fields. These transformations are included in the
Master Equation by coupling them to Sources. Here we show that there are new
local SUSY Actions where the Chiral SUSY transformations are realized in terms
of transformations among both Fields and Sources. These Actions can be easily
obtained from the Chiral case by a very simple and local `Exchange
Transformation', which carries along all the interactions without difficulty.
For these new SUSY Actions, the SUSY charge does not exist in the relevant
sector, because Sources do not satisfy Equations of Motion.
Nevertheless, the `Exchange Transformation' ensures that the new Master
Equation is true for the new Action. As a consequence, the Master Equation also
is true for the new 1PI Generating Functional. This implies that a `Suppressed
SUSY Charge' version of SUSY is still present. SUSY certainly becomes more
obscure and less constrained in this case. But it is still very restrictive.
The new theories can be obtained from the old theories by using a special
technique, but it is not true that they are a sort of `broken version of
supersymmetry'. They are simply a new type of theory that is governed by
Supersymmetry, but without the use of Supercharges (except perhaps in some
sectors).
In particular the number of physical Bosonic and Fermionic degrees of Freedom
are not equal for these new (sub)-Actions, although there is still
Boson/Fermion mass degeneracy in a (sub)-Action, so long as there is still a
Boson present. Notably, there is even a SUSY (sub)-Action where the physical
Scalars are not present, so that the (sub)-Action contains physical Fermions
only. In this theory the degeneracy of Bosonic and Fermionic masses is
obviously not present.Comment: 21 pages This version has a better explanation of how and why these
new representations of SUSY can and do exist, without contradicting the known
results in SUSY theor
The SSM with Suppressed SUSY Charge
An earlier paper showed that it is possible to write down new SUSY Actions in
which it is not possible to define a Supersymmetry Charge. SUSY is defined in
these new Actions by the fact that they satisfy Master Equations. The new SUSY
Actions are very easy to write down. One simply takes a Chiral SUSY Action,
coupled to Gauge and other Chiral Multiplets, and even SuperGravity, if
desired. Then one creates a new Action from this by exchanging all or part of
the Scalar Field for a new Zinn Source , and the corresponding part of
the Zinn Source for a new Antighost Field . Since the original
Action satisfies a Master Equation, this exchange guarantees that the new
Action will satisfy the new Master Equation. As was shown in the earlier paper,
the new multiplets have fewer bosonic degrees of freedom than fermionic degrees
of freedom. This is possible because they do not have a Supercharge.
The resulting new SSM has no need for Squarks or Sleptons. It does not need
spontaneous breaking of SUSY, so that the cosmological constant problem does
not arise (at least at tree level). It mimics the usual non-supersymmetric
Standard Model very well, and the absence of large flavour changing neutral
currents is natural. There is no need for a hidden sector, or a messenger
sector, or explicit `soft' breaking of SUSY. Spontaneous Gauge Symmetry
Breaking implies the existence of two new very heavy Higgs Bosons with mass
13.4 TeV, slightly smaller than the energy of the LHC at 14 TeV. There is also
a curious set of Gauginos and Higgsinos which have exactly the same masses as
the Higgs and Gauge Bosons. These do not couple to the Quarks and Leptons,
except through the Higgs and Gauge Bosons.Comment: 19 pages. This version contains a better explanation of why and how
this theory can exis
An Irreducible Massive Superspin One Half Action Built From the Chiral Dotted Spinor Superfield
Although the chiral dotted spinor superfield should describe a Massive
Superspin One Half multiplet, it has not been obvious how to derive this from
an action. In this paper this is done by including a chiral undotted spinor
superfield, finding the BRST transformations that govern both of these, and
then finding the action as an invariant of the transformations. It turns out
that both kinds of spinor superfields are needed. Moreover, the BRST
transformations for the two kinds of chiral spinor superfields are generated
from each other by a special involution that exchanges Grassmann odd (even)
sources with Grassmann even (odd) fields.Comment: 13 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
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
