Non-linear duality invariant partially massless models?

Non-linear duality invariant partially massless models?

Article history: Received 10 November 2015 Accepted 9 December 2015 Available online 15 December 2015 Editor: M. Cvetič We present manifestly duality invariant, non-linear, equations of motion for maximal depth, partially massless higher spins. These are based on a first order, Maxwell-like formulation of the known partially massless systems. Our models mimic Dirac–Born–Infeld theory but it is ...

PM1⁄4EM? Partially massless duality invariance

is almost coeval with Maxwell’s equations themselves, although a proof of its validity awaited over a century [1,2]. In addition to countless generalizations of ‘‘duality’’ in field and string theory, it has led to an enormous variety of more precise analogs, in particular to spin 2 [2,3], then to all free massless (integer or half-integer) spin s > 0 systems in flat space [4,5]. In de Sitter (...

Duality and Massless Monopoles

Duality arguments suggest the existence of massless magnetic monopoles in gauge theories with the symmetry broken to a non-Abelian subgroup. I discuss how these arise and show how they are manifested as clouds of massless fields surrounding massive monopoles. The dynamics of these clouds is discussed, and the scattering of massless monopole clouds and massive monopoles is described.

New duality transformation in two-dimensional non-linear sigma models

A new T-duality transformation is found in two-dimensional non-linear sigma models. This is a straightforward generalisation of Abelian and non-Abelian T-dualities. It is shown, in particular, that a given non-linear sigma model can possess more than one dual theory. Finally, the construction of this duality is given a geometrical interpretation. e-mail: [email protected] CNRS UMR ...
