A proposal for the role of higher spin fields in Conformal Cyclic Cosmology
Anders K. H. Bengtsson
This paper proposes a research program into how the special properties of the cubic chiral higher spin gravity theory may play a role in conformal cyclic cosmology and black hole p…
Antiquity, Dark Ages and Renaissance of Light-Front Higher Spin Theory
Anders K H Bengtsson
These notes contain -- apart from some physics -- scattered reminiscences of everyday life at the Institute for Theoretical Physics in Göteborg in the early eighties. The text has…
Investigations into Light-front Quartic Interactions for Massless Fields (I): Non-constructibility of Higher Spin Quartic Amplitudes
Anders K. H. Bengtsson
The dynamical commutators of the light-front Poincaré algebra yield first order differential equations in the momenta for the interaction vertex operators. The homogeneous so…
Quartic amplitudes for Minkowski higher spin
Anders K. H. Bengtsson
The problem of finding general quartic interaction terms between fields of higher helicities on the light-front is discussed from the point of view of calculating the corresponding…
Notes on Cubic and Quartic Light-Front Kinematics
Anders K. H. Bengtsson
The purpose of this short note is to collect a set of formulas pertaining to momentum kinematics for higher spin light-front vertices. At least one of the formulas seems to be prev…
A Riccati type PDE for light-front higher helicity vertices
Anders K. H. Bengtsson
This paper is based on a curious observation about an equation related to the tracelessness constraints of higher spin gauge fields. The equation also occurs in the theory of conti…
