Supersymmetry with Central Charge: A Twofold Implementation
In this work, we analyze an extended supersymmetry with
central charge and develop its superspace formulation under two distinct
viewpoints. Initially, in the context of classical mechanics, we discuss the
introduction of deformed supersymmetric derivatives and their consequence on
the deformation of one-dimensional non-linear sigma model. After that,
considering a field-theoretical framework, we present an implementation of this
superalgebra in two dimensions, such that one of the coordinates is related to
the central charge. As an application, in this two-dimensional scenario, we
consider topological (bosonic) configurations of a special self-coupled matter
model and present a non-trivial fermionic solution.Comment: Accepted version in Advances in High Energy Physic
Renormalizability of super Yang-Mills theory in Landau gauge with a Stueckelberg-like field
We construct a vector gauge invariant transverse field configuration ,
consisting of the well-known superfield and of a Stueckelberg-like chiral
superfield. The renormalizability of the Super Yang Mills action in the Landau
gauge is analyzed in the presence of a gauge invariant mass term , with a power series in . Unlike the
original Stueckelberg action, the resulting action turns out to be
renormalizable to all orders.Comment: 19 page
Aspects of the gauge boson-gaugino mixing in a supersymmetric scenario with Lorentz-symmetry violation
We write down an supersymmetric extension for non-Abelian
gauge theories in (1+3) dimensions with a Lorentz- and CPT-violating term of
the Carroll-Field-Jackiw type. By including effects of the background
(supersymmetric) fermion bilinears that accompany Lorentz-symmetry violation in
a Carroll-Field-Jackiw scenario, we investigate both the gauge boson and
gaugino dispersion relations in order to compute their respective masses in
terms of the background structures. Such results open up a potential path
towards a possible mechanism for gaugino-gauge boson conversion, an analogue of
the Primakoff effect, induced here not by an external magnetic field, but
instead by the (Majorana) fermionic sector of the supersymmetry multiplet in
the backstage of the Lorentz-symmetry violation.Comment: 21 pages, no figures. All the Sections have been highly improved.
