A CFT interpretation of cosmological correlation functions in α−vacua in de-Sitter space
Journal of High Energy Physics, 2023 De-Sitter(dS) space allows for a generalized class of vacua, known as α–vacua, described by some parameters. The Bunch-Davies (BD) vacuum is a point in this parameter space. The cosmological correlation function in BD vacuum in four dimensions and can be

Tensors and spinors in de Sitter space
Journal of High Energy Physics, 2022 We construct the Wightman function for symmetric traceless tensors and Dirac fermions in dS d+1 in a coordinate and index free formalism using a d + 2 dimensional ambient space. We expand the embedding space formalism to cover spinor and tensor fields in

Modular differential equations with movable poles and admissible RCFT characters
Journal of High Energy Physics, 2023 Studies of modular linear differential equations (MLDE) for the classification of rational CFT characters have been limited to the case where the coefficient functions (in monic form) have no poles, or poles at special points of moduli space.

Magic fermions: Carroll and flat bands
Journal of High Energy Physics, 2023 The Carroll algebra is constructed as the c → 0 limit of the Poincare algebra and is associated to symmetries on generic null surfaces. In this paper, we begin investigations of Carrollian fermions or fermions defined on generic null surfaces. Due to the

Conformal bootstrap in momentum space at finite volume
Journal of High Energy Physics, 2023 In this paper, we Fourier transform the Wightman function concerning energy and angular momentum on the S D−1 spatial slice in radial quantization in D = 2, 3 dimensions.

An integer basis for celestial amplitudes
Journal of High Energy Physics, 2023 We present a discrete basis of solutions of the massless Klein-Gordon equation in 3 + 1 Minkowski space which transform as 𝔰𝔩(2, ℂ) Lorentz/conformal primaries and descendants, and whose elements all have integer conformal dimension.

Hecke relations among 2d fermionic RCFTs
Journal of High Energy Physics, 2023 Recently, Harvey and Wu proposed a suitable Hecke operator for vector-valued SL(2, ℤ) modular forms to connect the characters of different 2d rational conformal field theories (RCFTs).

DBI Realizations of the Pseudo-Conformal Universe and Galilean Genesis Scenarios [PDF]
, 2012 The pseudo-conformal universe is an alternative to inflation in which the early universe is described by a conformal field theory on approximately flat space-time. The fields develop time-dependent expectation values, spontaneously breaking the conformal

Non-Lorentzian RG flows and supersymmetry
Journal of High Energy Physics, 2019 We describe a general process where a non-Lorentzian rescaling of a supersymmetric field theory leads to a scale-invariant fixed point action without Lorentz invariance but where the supersymmetry is preserved or even enhanced. We apply this procedure to

Relations among polarized and unpolarized splitting functions beyond leading order [PDF]
, 1998 The role of various symmetries in the evaluation of splitting functions and coefficient functions is discussed. The scale invariance in hard processes is known to be a guiding tool to understand the dynamics.
