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

Duality after supersymmetry breaking [PDF]
, 1998 Starting with two supersymmetric dual theories, we imagine adding a chiral perturbation that breaks supersymmetry dynamically. At low energy we then get two theories with soft supersymmetry-breaking terms that are generated dynamically.

Dynamical supersymmetry breaking
, 1998 Dynamical supersymmetry breaking is a fascinating theoretical problem that is also of phenomenological significance. A better understanding of this phenomenon can help in model building, which in turn is useful in guiding the search for supersymmetry ...

Spontaneous supersymmetry breaking in the 2D N=1 Wess-Zumino Model [PDF]
, 2014 We study the phase diagram of the two-dimensional N=1 Wess-Zumino model on the lattice using Wilson fermions and the fermion loop formulation. We give a complete nonperturbative determination of the ground state structure in the continuum and infinite ...

Three-form multiplet and supersymmetry breaking
Journal of High Energy Physics, 2017 Recently, a nilpotent real scalar superfield V was introduced in [1] as a model for the Goldstino. It contains only two independent component fields, the Goldstino and the auxiliary D-field.

Asymptotically‐Flat Black Hole Solutions in Symmergent Gravity
Fortschritte der Physik, Volume 72, Issue 4, April 2024.Abstract Symmergent gravity is an emergent gravity model with an R+R2$R+R^2$ curvature sector and an extended particle sector having new particles beyond the known ones. With constant scalar curvature, asymptotically flat black hole solutions are known to have no sensitivity to the quadratic curvature term (coefficient of R2$R^2$). With variable scalar

Supersymmetry breaking and 4 dimensional string models
, 2003 A family of superpotentials is constructed which may be relevant to supersymmetry breaking in 4 dimensional (0,1) heterotic string models. The scale of supersymmetry breaking, as well as the coupling constant, would be stable and could not run away to ...

Gauge-mediated supersymmetry breaking within the dynamical messenger sector
, 1998 We consider the idea of combining the supersymmetry breaking and messenger sectors in models of gauge-mediated supersymmetry breaking. We discuss the advantages and problems of such models, and present an existence proof by constructing an explicit ...

New models of gauge- and gravity-mediated supersymmetry breaking
, 1997 We show that supersymmetry breaking in a class of theories with SU(N) × SU(N-2) gauge symmetry can be studied in a calculable σ model. We use the s model to show that the supersymmetry-breaking vacuum in these theories leaves a large subgroup of flavor ...

Conformal Supersymmetry Breaking and Dynamical Tuningof the Cosmological Constant [PDF]
, 2008 We propose 'conformal supersymmetry breaking' models, which tightly relate the conformal breaking scale (i.e. R-symmetry breaking scale) and the supersymmetry breaking scale.
