Auxiliary field deformations of (semi-)symmetric space sigma models by Daniele Bielli, Christian Ferko, Liam Smith, Gabriele Tartaglino-Mazzucchelli

“…This gives rise to a new infinite family of classically integrable ℤ2 and ℤ4 coset models of the form which are of interest in applications of integrability to worldsheet string theory and holography. We demonstrate that every theory in this infinite class admits a zero-curvature representation for its equations of motion by exhibiting a Lax connection.…”

A heterotic Kähler gravity and the distance conjecture by Javier José Murgas Ibarra, Paul-Konstantin Oehlmann, Fabian Ruehle, Eirik Eik Svanes

“…We investigate properties of this new holomorphic theory, and in particular connections to the swampland distance conjecture in the context of heterotic string theory. In the process, we define a new type of symplectic cohomology theory, where the background complex structure Beltrami differential plays the role of the symplectic form.…”

Susy breaking soft terms in the supersymmetric Pati-Salam landscape from intersecting D6-branes by Mudassar Sabir, Adeel Mansha, Tianjun Li, Zhi-Wei Wang

“…Abstract We investigate the supersymmetry breaking soft terms for all the viable models in the complete landscape of three-family supersymmetric Pati-Salam models arising from intersecting D6-branes on a 𝕋6 /(ℤ2 × ℤ2) orientifold in type IIA string theory. The calculations are performed in the general scenario of u-moduli dominance with the s-moduli turned on, where the soft terms remain independent of the Yukawa couplings and the Wilson lines. …”

Susy at the FPF by Luis A. Anchordoqui, Ignatios Antoniadis, Karim Benakli, Jules Cunat, Dieter Lüst

“…The failure to observe signals of sparticle production at the large hadron collider (LHC) has eroded the central motivation for SUSY breaking at the weak scale. However, String Theory requires SUSY at the fundamental scale $$M_s$$ M s and hence SUSY could be broken at some high scale below $$M_s$$ M s . …”

Matrix theory reloaded: a BPS road to holography by Chris D. A. Blair, Johannes Lahnsteiner, Niels A. Obers, Ziqi Yan

“…We conjecture that a DLCQ n /DLCQ m correspondence, with m > n, captures the notion of holography in string theory. In particular, AdS5/CFT4 can be viewed as an example of DLCQ0/DLCQ1, with the extra DLCQ on the field theory side corresponding to the near-horizon limit in the bulk geometry. …”

Drinfel’d doubles, twists and all that. . . in stringy geometry and M theory by Aybike Çatal-Özer, Keremcan Doğan, Cem Yetişmişoğlu

“…Abstract Drinfel’d doubles of Lie bialgebroids play an important role in T-duality of string theories. In the presence of H and R fluxes, Lie bialgebroids should be extended to proto Lie bialgebroids. …”
