Odd dimensional nonlocal Liouville conformal field theories

Journal of High Energy Physics, 2022
We construct Euclidean Liouville conformal field theories in odd number of dimensions. The theories are nonlocal and non-unitary with a log-correlated Liouville field, a Q $$ \mathcal{Q} $$ -curvature background, and an exponential Liouville-type ...

Going down from a 3-form in 16 dimensions

, 2002
Group theory indicates the existence of a SO(8)×SO(7)⊂SO(16) invariant self-duality equation for a 3-form in 16 dimensions. It is a signal for interesting topological field theories, especially on 8-dimensional manifolds with holonomy group smaller than ...

Negative energy enhancement in layered holographic conformal field theories

, 2021
Using a holographic model, we study quantum field theories with a layer of one CFT surrounded by another CFT, on either a periodic or an infinite direction.

Liouville theory: an introduction to rigorous approaches

Journal of High Energy Physics
In recent years, a surprisingly direct and simple rigorous understanding of quantum Liouville theory has developed. We aim here to make this material more accessible to physicists working on quantum field theory.

E 8 instantons on type-A ALE spaces and supersymmetric field theories

Journal of High Energy Physics, 2017
We consider the 6d superconformal field theory realized on M5-branes probing the E 8 end-of-the-world brane on the deformed and resolved ℂ 2/ℤ k singularity.

The Thousand-Pulsar-Array programme on MeerKAT–XVI. Mapping the Galactic magnetic field with pulsar observations

Measuring the magnetic field of the Milky Way reveals the structure and evolution of the Galaxy. Pulsar rotation measures (RMs) provide a means to probe this Galactic magnetic field (GMF) in three dimensions.

Bounds on 4D conformal and superconformal field theories [PDF]

, 2011
We derive general bounds on operator dimensions, central charges, and OPE coefficients in 4D conformal and N = 1 superconformal field theories. In any CFT containing a scalar primary ϕ of dimension d we show that crossing symmetry of ⟨ϕϕϕϕ⟩ implies a ...

Finite volume form factors in integrable theories

Journal of High Energy Physics
We develop a new method to calculate finite size corrections for form factors in two-dimensional integrable quantum field theories. We extract these corrections from the excited state expectation value of bilocal operators in the limit when the operators

Discrete gauging in six dimensions

Journal of High Energy Physics, 2018
When n M5 branes coincide on an A type singularity, ℂ2 /ℤ k , there is a multitude of tensionless strings which arise in the spectrum. The low energy theory when all M5 branes are separated at the singularity is given by a linear quiver with parameters n

Nonrelativistic Naturalness in Aristotelian Quantum Field Theories [PDF]

, 2017
Some of the most fundamental questions in theoretical physics can be formulated as puzzles of naturalness, such as the cosmological constant problem and the Higgs mass hierarchy problem.
