Particle actions and brane tensions from double and exceptional geometry

Journal of High Energy Physics, 2017
Massless particles in n + 1 dimensions lead to massive particles in n dimensions on Kaluza-Klein reduction. In string theory, wrapped branes lead to multiplets of massive particles in n dimensions, in representations of a duality group G. By encoding the

One-loop phenomenology in brane models [PDF]

, 2005
Particular examples of one-loop string effects are explored in the context of brane-based realizations of the Standard Model. We firstly examine the consequences of a phenomenon known as Kinetic Mixing, which couples hidden U(1) gauge factors to visible ...

Wrapping rules (in) string theory

Journal of High Energy Physics, 2018
In this paper we show that the number of all 1/2-BPS branes in string theory compactified on a torus can be derived by universal wrapping rules whose formulation we present.

Partonic description of a supersymmetric p-brane [PDF]

Journal of High Energy Physics, 2010
We consider supersymmetric extensions of a recently proposed partonic description of a bosonic p-brane which reformulates the Nambu-Goto action as an interacting multi-particle action with Filippov-Lie algebra gauge symmetry. We construct a worldline supersymmetric action by postulating, among others, a p-form fermion.

Microscopic Calabi-Yau Black Holes in String Theory [PDF]

, 2011
In this thesis we study microscopic aspects of Calabi-Yau black holes in string theory. We compute the absorption cross-section of the space-time massless scalars by the world-volume of D2-branes, wrapped on the S2 of an AdS_2 x S^2 x CY_3 geometry of a ...

One loop phenomenology of type II string theory: intersecting d-branes and noncommutativity [PDF]

, 2007
We examine one loop amplitudes for open and closed strings in certain D-brane configurations, and investigate the consequences for phenomenology. Initially we consider open strings at D6-brane intersections.

From Branes to Branes

, 2003
We use the `branes within branes' approach to study the appearance of stable $ (p-2)-branes and unstable (p-1)-branes in type II string theory from p-brane--p-antibrane pairs.Our goal is to describe the emergence of these lower dimensional branes from ...

A story of non-conformal branes: spindles, disks, circles and black holes

Journal of High Energy Physics
We consider the (p + 2)-dimensional gauged supergravities arising as a consistent truncation of type II on S 8−p , which are associated with the near-horizon limit of Dp-branes, for p = 2, 4, 5, 6 (and NS5-branes for p = 5).
