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.

Modular graph functions and odd cuspidal functions. Fourier and Poincaré series

Journal of High Energy Physics, 2019
Modular graph functions are SL(2, ℤ)-invariant functions associated with Feynman graphs of a two-dimensional conformal field theory on a torus of modulus τ. For one-loop graphs they reduce to real analytic Eisenstein series. We obtain the Fourier series,

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 ...

Revisiting noninteracting string partition functions in Rindler space [PDF]

, 2016
We revisit noninteracting string partition functions in Rindler space by summing over fields in the spectrum. In field theory, the total partition function splits in a natural way into a piece that does not contain surface terms and a piece consisting of

One-loop monodromy relations on single cuts

Journal of High Energy Physics, 2017
The discovery of colour-kinematic duality has led to significant progress in the computation of scattering amplitudes in quantum field theories. At tree level, the origin of the duality can be traced back to the monodromies of open-string amplitudes ...

Perturbative string thermodynamics near black hole horizons [PDF]

, 2015
We provide further computations and ideas to the problem of near-Hagedorn string thermodynamics near (uncharged) black hole horizons, building upon our earlier work JHEP 1403 (2014) 086. The relevance of long strings to one-loop black hole thermodynamics

Rounding out the story of higher derivative consistent truncations

Journal of High Energy Physics
At the two-derivative order, the group manifold reduction of heterotic supergravity on S 3 results in a half-maximal 7D gauged supergravity coupled to three vector multiplets, and a further truncation can be taken to remove the vector multiplets.

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 ...
