Spectrum of Massive and Massless Ambitwistor Strings
Christian Kunz
Inspired by recent work arXiv:2301.11227 on massive ambitwistor strings this paper examines the spectrum of such models using oscillator expansions. The spectrum depends heavily on…
A Kerr/CFT Correspondence in Twistor Space
Christian Kunz
Ingoing and outgoing principal null geodesics in Kerr spacetimes are characterized as part of parametrized families of strings in complex Kerr geometry and are associated with holo…
A Note on Classical Aspects of the Four Dimensional Anomaly-Free Twistor String
Christian Kunz
The recently introduced anomaly-free twistor string in four dimensions is shown to be defined not just in flat but also in curved twistor space. Further, arguments are given that t…
Spectrum, Scattering Amplitudes, and String Field Theory of 4 Dimensional Twistor String
Christian Kunz
The recently introduced anomaly-free twistor string in 4 dimensions is further explored. The spectrum based on the physical states and its Minkowski interpretation are examined. Sc…
Four Dimensional Anomaly-Free Twistor String
Christian Kunz
This paper presents a covariant twistor string model in four dimensions coupled to two-dimensional worldsheet gravity with an anomaly-free BRST charge. The model contains two twist…
