New supersymmetry algebras from partial supersymmetry breaking [PDF]
arXiv, 1998 In this talk we will study the partial breaking of supersymmetry in flat and anti de Sitter space. We will see that partial breaking in flat space can be accomplished using either of two representations for the massive N=1 spin-3/2 multiplet. We will "unHiggs" each representation and find a new N=2 supergravity and a new N=2 supersymmetry algebra.

Planarizable Supersymmetric Quantum Toboggans
Symmetry, Integrability and Geometry: Methods and Applications, 2011 In supersymmetric quantum mechanics the emergence of a singularity may lead to the breakdown of isospectrality between partner potentials. One of the regularization recipes is based on a topologically nontrivial, multisheeted complex deformations of the ...

Topological quantum pump of strongly interacting fermions in coupled chains
New Journal of Physics, 2019 We analyse a tight binding model of two coupled chains with strongly interacting fermions. Depending on the parameter w , the many body lowest energy band consists of either single particles or bound pairs.

Standard model alignment scenarios for Higgs bosons
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2016 This paper describes the model NMSSM with effective explicit and spontaneous CP-violations, and additional mixing of CP-even and CP-odd Higgs bosons states. The neutral Higgs bosons masses and decay widths were calculated at fixed parameters of the model

Supersymmetrical Separation of Variables in Two-Dimensional Quantum Mechanics
Symmetry, Integrability and Geometry: Methods and Applications, 2010 Two different approaches are formulated to analyze two-dimensional quantum models which are not amenable to standard separation of variables. Both methods are essentially based on supersymmetrical second order intertwining relations and shape invariance -

Higgs mass determination in supersymmetry
, 2015 A bstractWe present the state-of-the-art of the effective field theory computation of the MSSM Higgs mass, improving the existing ones by including extra threshold corrections. We show that, with this approach, the theoretical uncertainty is within 1 GeV

Supersymmetry Breakings and Fermat's Last Theorem
, 1994 A mechanism of supersymmetry breaking in two or four-dimensions is given, in which the breaking is related to the Fermat's last theorem. It is shown that supersymmetry is exact at some irrational number points in parameter space, while it is broken at ...

Resolutions of Identity for Some Non-Hermitian Hamiltonians. II. Proofs
Symmetry, Integrability and Geometry: Methods and Applications, 2011 This part is a continuation of the Part I where we built resolutions of identity for certain non-Hermitian Hamiltonians constructed of biorthogonal sets of their eigen- and associated functions for the spectral problem defined on entire axis.
