Shift operators from the simplex representation in momentum-space CFT
Journal of High Energy Physics, 2023 We derive parametric integral representations for the general n-point function of scalar operators in momentum-space conformal field theory. Recently, this was shown to be expressible as a generalised Feynman integral with the topology of an (n − 1 ...

Conformal Symmetry and Cosmological Entropy Production [PDF]
, 2002 : Introducing an effective refraction index of an isotropic cosmic medium, we investigate the cosmological fluid dynamics which is consistent with a conformal, timelike symmetry of a corresponding "optical" metric.

A spacetime derivation of the Lorentzian OPE inversion formula
Journal of High Energy Physics, 2018 Caron-Huot has recently given an interesting formula that determines OPE data in a conformal field theory in terms of a weighted integral of the four-point function over a Lorentzian region of cross-ratio space.

Topics in Supersymmetry Breaking and Gauge/Gravity Dualities [PDF]
, 2010 The thesis covers two topics in string theory and quantum field theory. First, we realize metastable vacua in various supersymmetric gauge theories. Specifically, we consider the Coulomb branch of any N = 2 supersymmetric gauge theory, and perturb it by ...

Towards a supersymmetric symmetry in the celestial conformal field theory
Physical Review, 2022 The w1+∞ symmetry algebra appears in the Einstein–Yang–Mills theory, proposed recently by Strominger. In this paper, we derive the supersymmetric w1+∞ symmetry by using the known results on the operator product expansions (OPEs) between the graviton, gravitino, gluon, and gluino in the supersymmetric version of the above theory.

On the positive geometry of conformal field theory
Journal of High Energy Physics, 2019 It has long been clear that the conformal bootstrap is associated with a rich geometry. In this paper we undertake a systematic exploration of this geometric structure as an object of study in its own right. We study conformal blocks for the minimal SL(2,

Exact conformal blocks for the W-algebras, twist fields and isomonodromic deformations [PDF]
, 2015 We consider the conformal blocks in the theories with extended conformal W-symmetry for the integer Virasoro central charges. We show that these blocks for the generalized twist fields on sphere can be computed exactly in terms of the free field theory ...
