Probe brane dynamics on cosmological brane backgrounds
Physics Letters B, 2014 We consider the dynamics of a single probe brane on various cosmological brane backgrounds. The on-shell condition of the static probe brane leads to the supersymmetric intersection rules for static BPS configurations, though the cosmological backgrounds

Relaxing the W′ Constraint on Compact Extradimension
Advances in High Energy Physics, 2022 In this paper, we study the constraint on brane tension and compactification scale for models with brane fluctuations using the results from the direct search of W′ at 13 TeV LHC, with an integrated luminosity of 36.1fb−1, in the case for which branon ...

Brane dimers and quiver gauge theories [PDF]
, 2005 We describe a technique which enables one to quickly compute an infinite number of toric geometries and their dual quiver gauge theories. The central object in this construction is a ``brane tiling,'' which is a collection of D5-branes ending on an NS5 ...

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.

, 1999 We discuss a set of universal couplings between superstring Ramond-Ramond gauge fields and the gauge fields internal to D-branes, with emphasis on their topological consequences, and argue that instanton solutions in these internal theories are equivalent to D-branes. A particular example is the Dirichlet 5-brane in type I theory, which Witten recently

Journal of Adolescent &Adult Literacy, Volume 68, Issue 4, Page 325-329, January/February 2025.Abstract Research shows little benefit from phonics instruction in Grades 2 through 12. However, more recent studies show that students who fall below a decoding threshold fail to benefit from other kinds of reading instruction. This exploration of the evidence suggests that these students are likely to need support in the reading and spelling of ...

Journal of High Energy Physics, 2014 T-branes are a non-abelian generalization of intersecting branes in which the matrix of normal deformations is nilpotent along some subspace. In this paper we study the geometric remnant of this open string data for six-dimensional F-theory vacua. We show that in the dual M-theory / IIA compactification on a smooth Calabi-Yau threefold X, the geometric

Emergent de Sitter cosmology near black hole horizon
Journal of High Energy Physics, 2022 We propose an effective model for an exponentially expanding universe in the brane-world scenario. The setup consists of a 5D black hole and a brane close to the black hole horizon.

Bianchi attractors: a classification of extremal black brane geometries [PDF]
, 2012 A bstractExtremal black branes are of interest because they correspond to the ground states of field theories at finite charge density in gauge/gravity duality.

T‐Symmetry in String Geometry Theory
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T‐symmetry. In the case of the dimensional reduction in space‐like directions, the T‐symmetry transformation gives the T‐dual transformation between the Type ...
