Scattering of Quantum Particles in de Sitter Spacetime I: The Formalism
Tomasz R. Taylor, Bin Zhu
We develop a formalism for computing the scattering amplitudes in maximally symmetric de Sitter spacetime with compact spatial dimensions. We describe quantum states by using the r…
Ambitwistor Yang-Mills Theory Revisited
Leron Borsten, Branislav Jurco, Hyungrok Kim +2
Inspired by the Movshev-Mason-Skinner Cauchy-Riemann (CR) ambitwistor approach, we provide a rigorous yet elementary construction of a twisted CR holomorphic Chern-Simons action on…
The BRST quantisation of chiral BMS-like field theories
José Figueroa-O'Farrill, Girish S Vishwa
The BMS Lie algebra belongs to a one-parameter family of Lie algebras obtained by centrally extending abelian extensions of the Witt algebra by a tensor density representation.…
Complex Symplectic Contractions and 3d Mirrors
Andrew Dancer, Julius F. Grimminger, Johan Martens +1
We propose magnetic quivers for the complex-symplectic contraction spaces, which are related to implosions and have a natural interpretation in terms of the Moore-Tachikawa categor…
Gravitational Bound Waveforms from Amplitudes
Tim Adamo, Riccardo Gonzo, Anton Ilderton
With the aim of computing bound waveforms from scattering amplitudes, we explore gravitational two-body dynamics using the Schwinger-Dyson equations and Bethe-Salpeter recursion. W…
Galilei particles revisited
José Miguel Figueroa-O'Farrill, Simon Pekar, Alfredo Pérez +1
We revisit the classifications of classical and quantum galilean particles: that is, we fully classify homogeneous symplectic manifolds and unitary irreducible projective represent…
