We review the status and present range of applications of the “string-inspired” approach to
perturbative quantum field theory. This formalism offers the possibility of computing effective …

A bstract Picture yourself in the wave zone of a gravitational scattering event of two massive,
spinning compact bodies (black holes, neutron stars or stars). We show that this system of …

We show that to cubic order double field theory is encoded in Yang-Mills theory. To this end
we use algebraic structures from string field theory as follows: The L∞-algebra of Yang-Mills …

A bstract There has been a renewed interest in the description of dressed asymptotic states
à la Faddeev-Kulish. In this regard, a worldline representation for asymptotic states dressed …

Perturbative quantum field theory usually uses second quantisation and Feynman diagrams.
The worldline formalism provides an alternative approach based on first quantised particle …

The N= 2 spinning particle action describes the propagation of antisymmetric tensor fields,
including vector fields as a special case. In this paper we study the path integral quantization …

In this work the worldline quantum field theory (WQFT) approach to computing observables
of the classical general relativistic two-body system is presented. Compact bodies such as …

A bstract We derive manifestly covariant actions of spinning particles starting from coadjoint
orbits of isometry groups, by using Hamiltonian reductions. We show that the defining …

The classic Abraham-Lorentz-Dirac self-force of pointlike particles is generalized within an
effective field theory setup to include linear spin and susceptibility effects described …

Free Lagrangians are found both for gauge and non-gauge bosonic conformal fields of any
symmetry type and in any space–time dimension. Conformal gauge fields of various types …
