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 . …”

Exact flux vacua, symmetries, and the structure of the landscape by Thomas W. Grimm, Damian van de Heisteeg

“…Abstract Identifying flux vacua in string theory with stabilized complex structure moduli presents a significant challenge, necessitating the minimization of a scalar potential complicated by infinitely many exponential corrections. …”

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. …”

Investigating 9d/8d non-supersymmetric branes and theories from supersymmetric heterotic strings by Yuta Hamada, Arata Ishige

“…Abstract We consider heterotic string theories in nine and eight dimensions. We identify the disconnected part of the spacetime gauge group by studying the outer automorphism of the charge lattices. …”

The geometry of autonomous metrical multi-time Lagrange space of electrodynamics by Mircea Neagu

“…The aim of this paper is to create a large geometrical background for the study of important branch of physics: electrodynamics, bosonic strings theory, magneto-hydrodynamics, and so forth. The geometrical construction is realized on the 1-jet fibre bundle J1(T,M) and is produced by a given quadratic multi-time Lagrangian function L. …”

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. …”
