Safe gauge-string correspondence by Soo-Jong Rey, Francesco Sannino

“…Here we develop the ‘safe’ gauge-string correspondence program according to which d-dimensional safe gauge theories, admitting the 't Hooft-Veneziano limit, are holographically dual to (d+1)-dimensional safe noncritical string theories on asymptotically anti-de Sitter space. …”

Higher-form symmetries of 6d and 5d theories by Bhardwaj, L, Schafer-Nameki, S

“…We describe general methods for determining higher-form symmetry groups of known 5d and 6d superconformal field theories (SCFTs), and 6d little string theories (LSTs). The 6d theories can be described as supersymmetric gauge theories in 6d which include both ordinary non-abelian 1-form gauge fields and also abelian 2-form gauge fields. …”

On universal splittings of tree-level particle and string scattering amplitudes by Qu Cao, Jin Dong, Song He, Canxin Shi, Fanky Zhu

“…Based on these, we provide a systematic and detailed study of the splitting behavior for essentially all ingredients which appear as integrands for open- and closed-string amplitudes as well as Cachazo-He-Yuan (CHY) formulas, including Parke-Taylor factors, correlators in superstring and bosonic string theories, and CHY integrands for a variety of amplitudes of scalars, gluons and gravitons. …”

Anisotropic massive Brans–Dicke gravity extension of the standard $$\Lambda $$ Λ CDM model by Özgür Akarsu, Nihan Katırcı, Neşe Özdemir, J. Alberto Vázquez

“…We also point out the interesting features of the model in the case of negative $$\omega $$ ω values; for instance, the constraints on $$\Omega _{\sigma ^2,0}$$ Ωσ2,0 could be relaxed considerably, the values of $$\omega \sim -1$$ ω∼-1 (relevant to string theories) predict dramatically different dynamics for the expansion anisotropy.…”

G-structures and superstrings from the worldsheet by Fiset, M

“…<p>G-structures, where G is a Lie group, are a uniform characterisation of many differential geometric structures of interest in supersymmetric compactifications of string theories. Calabi–Yau n-folds for instance have torsion-free SU(n)-structure, while more general structures with non-zero torsion are required for heterotic flux compactifications. …”

Physics Beyond the Standard Model with Future X-Ray Observatories: Projected Constraints on Very-light Axion-like Particles with Athena and AXIS by Júlia Sisk-Reynés, Christopher S. Reynolds, Michael L. Parker, James H. Matthews, M. C. David Marsh

“…Axion-like particles (ALPs) are well-motivated extensions of the Standard Model of Particle Physics and a generic prediction of some string theories. X-ray observations of bright active galactic nuclei (AGNs) hosted by rich clusters of galaxies are excellent probes of very-light ALPs, with masses $\mathrm{log}({m}_{{\rm{a}}}/\mathrm{eV})\lt -12.0$ . …”

Decision procedures for path feasibility of string-manipulating programs with complex operations by Chen, T, Hague, M, Lin, AW, Rümmer, P, Wu, Z

“…The semantic conditions also strictly subsume existing decidable string theories (e.g. straight-line fragments, and acyclic logics), and most existing benchmarks (e.g. most of Kaluza’s, and all of SLOG’s, Stranger’s, and SLOTH’s benchmarks). …”
