“…By analyzing the C µνρ -field equation, we have found that our system maintains supersymmetry, even after adding a Fayet-Iliopoulos-like term L ξH [18]. This result is based on the peculiar feature that even though only the dual H ≡ (1/4!…”

Dilaton and second-rank tensor fields as supersymmetric compensators

We formulate a supersymmetric theory in which both a dilaton and a secondrank tensor play roles of compensators. The basic off-shell multiplets are a linear multiplet (B µν , χ, ϕ) and a vector multiplet (A µ , λ; C µνρ ), where ϕ and B µν are respectively a dilaton and a second-rank tensor. The third-rank tensor C µνρ in the vector multiplet is 'dual' to the conventional D -field with 0 on-shell or 1 off-shell degree of freedom. The dilaton ϕ is absorbed into one longitudinal component of A µ , making it massive. Initially, B µν has 1 on-shell or 3 off-shell degrees of freedom, but it is absorbed into the longitudinal components of C µνρ . Eventually, C µνρ with 0 on-shell or 1 off-shell degree of freedom acquires in total 1 on-shell or 4 off-shell degrees of freedom, turning into a propagating massive field. These basic multiplets are also coupled to chiral multiplets and a supersymmetric Dirac-Born-Infeld action. Some of these results are also reformulated in superspace. The proposed mechanism may well provide a solution to the long-standing puzzle of massless dilatons and second-rank tensors in supersymmetric models inspired by string theory.

“…Studying supersymmetry-breaking scenarios goes nevertheless beyond the scopes of the present work. We just point out that supersymmetry can be spontaneously broken if the so-called D-term and/or the F-term in the MSSM scalar potential have non-zero vacuum expectation values, which can be achieved by means of the Fayet-Iliopoulos [33] or O'Raifeartaigh [34] mechanisms, respectively. 8) The sfermion squared masses can thus be expressed as the sum of a soft term m 2 0 , often set to the same value for both squarks and sleptons at a given scale, and the corrections due to D-and F-terms [18].…”

Searching for heavy neutral gauge bosons Z ′ , predicted in extensions of the Standard Model based on a U(1) ′ gauge symmetry, is one of the challenging objectives of the experiments carried out at the Large Hadron Collider. In this paper, we study Z ′ phenomenology at hadron colliders according to several U(1) ′ -based models and in the Sequential Standard Model. In particular, possible Z ′ decays into supersymmetric particles are included, in addition to the Standard Model modes so far investigated. We point out the impact of the U(1) ′ group on the MSSM spectrum and, for a better understanding, we consider a few benchmarks points in the parameter space. We account for the D-term contribution, due to the breaking of U(1) ′ , to slepton and squark masses and investigate its effect on Z ′ decays into sfermions. Results on branching ratios and cross sections are presented, as a function of the MSSM and U(1) ′ parameters, which are varied within suitable ranges. We pay special attention to final states with leptons and missing energy and make predictions on the number of events with sparticle production in Z ′ decays, for a few values of integrated luminosity and centre-of-mass energy of the LHC.

We investigate the microphysics of supersymmetric cosmic strings. In particular we focus on the vortices admitted by N = 1 supersymmetric abelian Higgs models. We find the vortex solutions and demonstrate that the two simplest supersymmetric cosmic string models admit fermionic superconductivity. Further, by using supersymmetry transformations, we show how to solve for the fermion zero modes giving rise to string superconductivity in terms of the background string fields.
