Mellin amplitudes for 1 CFT
Lorenzo Bianchi, Gabriel Bliard, Valentina Forini +1
We define a Mellin amplitude for CFT four-point functions. Its analytical properties are inferred from physical requirements on the correlator. We discuss the analytic continua…
Analytic bootstrap and Witten diagrams for the ABJM Wilson line as defect CFT
Lorenzo Bianchi, Gabriel Bliard, Valentina Forini +2
We study local operator insertions on 1/2-BPS line defects in ABJM theory. Specifically, we consider a class of four-point correlators in the CFT with SU superconform…
Roadmap on Wilson loops in 3d Chern-Simons-matter theories
Nadav Drukker, Diego Trancanelli, Lorenzo Bianchi +18
This is a compact review of recent results on supersymmetric Wilson loops in ABJ(M) and related theories. It aims to be a quick introduction to the state of the art in the field an…
Emitted Radiation and Geometry
Lorenzo Bianchi, Marco Billò, Francesco Galvagno +1
In conformal Super Yang-Mills theory, the energy emitted by an accelerated heavy particle is computed by the one-point function of the stress tensor operator in the…
New linearization and reweighting for simulations of string sigma-model on the lattice
Lorenzo Bianchi, Valentina Forini, Björn Leder +2
We study the discretized worldsheet of Type IIB strings in the Gubser-Klebanov-Polyakov background in a new setup, which eliminates a complex phase previously detected in the fermi…
Marginal deformations and defect anomalies
Lorenzo Bianchi
We deform a defect conformal field theory by an exactly marginal bulk operator and we consider the dependence on the marginal coupling of flat and spherical defect expectation valu…
