There is … WebMar 1, 2024 · Our interesting observation is the abrupt behavior of the system just when the theory touches the Higuchi bound [17], where the constraint structure of the system has a completely different character. Exactly at the Higuchi bound, one chain of constraints with four second class elements changes to a first class chain with three elements.
WebThe value of mg is precisely the Spin-2 gauge line appearing on the Λ - m 2 g phase diagram for Spin-2, the partially massless gauge lines introduced by Deser & Waldron in the m 2 g, Λ) phase plane and described as the Higuchi bound m 2 g = 2 Λ /3. Note that this graviton is unitary with only four polarization degrees of freedom (helicities ... WebFeb 22, 2024 · Mass and spin for classical strings in. We demonstrate that all rigidly rotating strings with center of mass at the origin of the static patch satisfy the Higuchi bound. This extends the observation of Noumi et al. for the open GKP-like string to all solutions of the Larsen-Sanchez class. We argue that strings violating the bound end up ...

WebMar 29, 2010 · 1. It is worth to mention that in a recent paper [7] a mechanism was described to modify the Higuchi bound in a de Sitter Universe by adding a suitable coupled ghost; in our work we will consider only canonically normalized scalar fields. See also [8] for the study of the behavior of a different model of infrared-modified gravity on FRW … earl wear \u0026 haywireWebOct 9, 2024 · The existence of light particles with spin during inflation is prohibited by the Higuchi bound. This conclusion can be evaded if one considers states with a sizeable coupling with the inflaton foliation, since this breaks the de Sitter isometries.

The quadratic red line is the Higuchi bound, while the linear blue line is the string Regge trajec-tory.
