Superstring amplitudes from the field-theory limit: an n-point map at one loop
Journal of High Energy PhysicsAre perturbative superstring amplitudes for massless external states just an α ′ dressing of super-Yang-Mills/supergravity? This is the case at tree level, where the worldsheet correlators at n points can be written in a natural worldsheet basis, such ...

The enhancon mechanism in string theory [PDF]
, 2002 The enhancon mechanism is a specific phenomenon in string theory which resolves a certain naked spacetime singularity arising in the supergravity description related to N = 2 supersymmetric pure gauge theory.

Non-perturbative Temperature Instabilities in N=4 Strings
, 1999 We derive a universal thermal effective potential, which describes all possible high-temperature instabilities of the known N=4 superstrings, using the properties of gauged N=4 supergravity.

Jumping spectra and vanishing couplings in heterotic Line Bundle Standard Models
Journal of High Energy Physics, 2019 We study two aspects of the physics of heterotic Line Bundle Standard Models on smooth Calabi-Yau threefolds. First, we investigate to what degree modern moduli stabilization scenarios can affect the standard model spectrum in such compactifications ...

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 ...

A relation between tree amplitudes of closed and open strings
, 1986 We derive a formula which expresses any closed string tree amplitude in terms of a sum of the products of appropriate open string tree amplitudes. This formula is applicable to the heterotic string as well as to the closed bosonic string and type II ...
