Volkov-Akulov theory and D-branes [PDF]
, 1997 The action of supersymmetric Born-Infeld theory (D-9-brane in a Lorentz covariant static gauge) has a geometric form of the Volkov-Akulov-type. The first non-linearly realized supersymmetry can be made manifest, the second world-volume supersymmetry is ...

Supersymmetry and dualities [PDF]
Nuclear Physics B - Proceedings Supplements, 1996 Duality transformations with respect to rotational isometries relate supersymmetric with non-supersymmetric backgrounds in string theory. We find that non-local world-sheet effects have to be taken into account in order to restore supersymmetry at the string level.

Species Scale and Primordial Gravitational Waves
Fortschritte der Physik, Volume 72, Issue 6, June 2024.Abstract The species scale is a field‐dependent UV cut‐off for any effective field theory weakly coupled to gravity. In this letter, it is shown that in the context of inflationary cosmology, a detection of primordial gravitational waves will set an upper bound on the decay rate |Λs′/Λs|$|\Lambda ^{\prime }_s/\Lambda _s|$ of the species scale ...

Scalar Supersymmetry in Bi-Spinor Gauge Theory [PDF]
arXiv, 2013 We describe a new realization of both global and local supersymmetry acting in spaces of commuting and anticommuting differential forms. Unlike the standard supersymmetry, it has Lorentz scalar transformation parameters. It is related but is not reducible to standard supersymmetry.
arxiv
Journal of the London Mathematical Society, Volume 109, Issue 6, June 2024.Abstract We construct a family of solvable lattice models whose partition functions include p$p$‐adic Whittaker functions for general linear groups from two very different sources: from Iwahori‐fixed vectors and from metaplectic covers. Interpolating between them by Drinfeld twisting, we uncover unexpected relationships between Iwahori and metaplectic ...

The Cigar-Shaped Background Metric with Supersymmetry Approaches and Thermal Properties of System [PDF]
Iranian Journal of Astronomy and AstrophysicsIn this paper, we introduce the cigar- shaped metric . Such metric can be obtained by the Schwarzschild black hole. Here, we write the Dirac equation in the corresponding background.

, 1994 We investigate the generic distribution of bosonic and fermionic states at all mass levels in non-supersymmetric string theories, and find that a hidden ``misaligned supersymmetry'' must always appear in the string spectrum.

Exploring T‐Duality for Self‐Dual Fields
Fortschritte der Physik, Volume 72, Issue 5, May 2024.Abstract Avatars of T‐duality within Sen's formalism for self‐dual field strengths in various dimensions are studied. This formalism is shown to naturally accommodate the T‐duality relation between Type IIA/IIB theories when compactified on a circle without the need for imposing the self‐duality constraint by hand, as is usually done. The study of this

A Generic Analysis of Nucleon Decay Branching Fractions in Flipped SU(5) Grand Unification
UniverseIn flipped SU(5) grand unified theories, the partial decay lifetimes of certain nucleon decay channels depend generically on an unknown unitary matrix, which arises when left-handed lepton fields are embedded into anti-fundamental representations of SU(5)
