Gauge-invariant fields and flow equations for Yang-Mills theories [PDF]
We discuss the concept of gauge-invariant fields for non-abelian gauge theories. Infinitesimal fluctuations around a given gauge field can be split into physical and gauge fluctuations. Starting from some reference field the gauge-invariant fields are constructed by consecutively adding physical fluctuations.

A gauge theory of second order in the derivatives of the auxiliary field is constructed following Utiyama's program. A novel field strength $G=\partial F+fAF$ arises besides the one of the first order treatment, $F=\partial A-\partial A+fAA$.

Semistrict Higher Gauge Theory [PDF]
We develop semistrict higher gauge theory from first principles. In particular, we describe the differential Deligne cohomology underlying semistrict principal 2-bundles with connective structures.

M2-brane surface operators and gauge theory dualities in Toda [PDF]
A bstractWe give a microscopic two dimensional N$$ \mathcal{N} $$ = (2, 2) gauge theory description of arbitrary M2-branes ending on Nf M5-branes wrapping a punctured Riemann surface. These realize surface operators in four dimensional N$$ \mathcal{N} $$

Non-associative gauge theory and higher spin interactions [PDF]
We give a framework to describe gauge theory on a certain class of commutative but non-associative fuzzy spaces. Our description is in terms of an Abelian gauge connection valued in the algebra of functions on the cotangent bundle of the fuzzy space. The

Conformal invariance of the subleading soft theorem in gauge theory [PDF]
In this note, I show that the recently proposed subleading soft factor in massless gauge theory uniquely follows from conformal symmetry of tree-level gauge theory amplitudes in four dimensions.

Perturbative quantum gravity as a double copy of gauge theory. [PDF]
In a previous paper we observed that (classical) tree-level gauge-theory amplitudes can be rearranged to display a duality between color and kinematics.

Non-perturbatively gauge-fixed compact U(1) lattice gauge theory
An extensive study of the compact U(1) lattice gauge theory with a higher derivative gauge-fixing term and a suitable counter-term has been undertaken to determine the nature of the possible continuum limits for a wide range of the parameters, especially

Scattering amplitudes and the double copy in topologically massive theories
Using the principles of the modern scattering amplitudes programme, we develop a formalism for constructing the amplitudes of three-dimensional topologically massive gauge theories and gravity.
