Shift operators from the simplex representation in momentum-space CFT

open access: yesJournal 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 ...

Relations among polarized and unpolarized splitting functions beyond leading order [PDF]

open access: yes, 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.

Galilean fermions: Classical and quantum aspects [PDF]

open access: yesPhysical Review D, 2023
We study the classical and quantum"properties"of Galilean fermions in 3+1 dimensions. We have taken the case of massless Galilean fermions minimally coupled to the scalar field.

Gapped dilatons in scale invariant superfluids [PDF]

open access: yesPhysical Review D, 2020
We study a paradigmatic model in field theory where a global $U(1)$ and scale symmetries are jointly and spontaneously broken. At zero density the model has a non-compact flat direction, which at finite density needs to be slightly lifted.

The inflationary wavefunction from analyticity and factorization [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2021
We study the analytic properties of tree-level wavefunction coefficients in quasi-de Sitter space. We focus on theories which spontaneously break dS boost symmetries and can produce significant non-Gaussianities.

Dualities between fermionic theories and the Potts model

open access: yesJournal of High Energy Physics, 2023
We show that a large class of fermionic theories are dual to a q → 0 limit of the Potts model in the presence of a magnetic field. These can be described using a statistical model of random forests on a graph, generalizing the (unrooted) random forest ...

Bootstrapping conformal QED3 and deconfined quantum critical point

open access: yesJournal of High Energy Physics, 2022
We bootstrap the deconfined quantum critical point (DQCP) and 3D Quantum Electrodynamics (QED3) coupled to N f flavors of two-component Dirac fermions. We show the lattice and perturbative results on the SO(5) symmetric DQCP are excluded by the bootstrap

Conformal symmetry in quantum gravity [PDF]

open access: yesThe European Physical Journal C
We study the problem of how to derive conformal symmetry in the framework of quantum gravity. We start with a generic gravitational theory which is invariant under both the general coordinate transformation (GCT) and Weyl transformation (or equivalently,

The Gross-Neveu-Yukawa archipelago

open access: yesJournal of High Energy Physics, 2023
We perform a bootstrap analysis of a mixed system of four-point functions of bosonic and fermionic operators in parity-preserving 3d CFTs with O(N) global symmetry. Our results provide rigorous bounds on the scaling dimensions of the O(N)-symmetric Gross-

Pseudoconformal equation of state in compact-star matter from topology change and hidden symmetries of QCD [PDF]

open access: yesScience China Physics Mechanics and Astronomy, 2018
We construct a new effective field theory approach to the equation of state (EoS), dubbed pseudo-confomal model “PCM”, for nuclear and compact star matter entirely in terms of effective hadron degrees of freedom.
