Magnetic charges for the graviton

Journal of High Energy Physics
Symmetries and conserved charges are investigated for linearised gravity and its dual formulation in terms of the dual graviton field. Conserved charges are constructed for the dual graviton theory that are associated with invariances of the dual ...

Thermal one- and two-graviton Green's functions in the temporal gauge [PDF]

, 2002
The thermal one- and two-graviton Green's function are computed using a temporal gauge. In order to handle the extra poles which are present in the propagator, we employ an ambiguity-free technique in the imaginary-time formalism. For temperatures T high

Zero‐curvature subconformal structures and dispersionless integrability in dimension five

Journal of the London Mathematical Society, Volume 110, Issue 6, December 2024.
Abstract We extend the recent paradigm “Integrability via Geometry” from dimensions 3 and 4 to higher dimensions, relating dispersionless integrability of partial differential equations to curvature constraints of the background geometry. We observe that in higher dimensions on any solution manifold, the symbol defines a vector distribution equipped ...

Quarks unter Hochdruck im Proton

Physik in unserer Zeit, Volume 55, Issue 6, Page 298-306, November 2024.
Schon vor etwa 90 Jahren haben Experimente gezeigt, dass das Proton kein punktförmiges Elementarteilchen ist, wie das Elektron, sondern eine innere Struktur aufweist. Dies war der Beginn der Protonstrukturforschung, die vor Kurzem mit der Messung des Drucks im Innern des Protons einen spannenden Höhepunkt erreicht hat.

Shapes of gravity: tensor non-Gaussianity and massive spin-2 fields

Journal of High Energy Physics, 2019
If the graviton is the only high spin particle present during inflation, then the form of the observable tensor three-point function is fixed by de Sitter symmetry at leading order in slow-roll, regardless of the theory, to be a linear combination of two

Low-Energy Behavior of Gluons and Gravitons from Gauge Invariance

, 2014
We show that at tree level, on-shell gauge invariance can be used to fully determine the first subleading soft-gluon behavior and the first two subleading soft-graviton behaviors. Our proofs of the behaviors for n-gluon and n-graviton tree amplitudes are

de Sitter State in Heterotic String Theory

Fortschritte der Physik, Volume 72, Issue 11, November 2024.
Abstract Recent no‐go theorems have ruled out four‐dimensional classical de Sitter vacua in heterotic string theory. On the other hand, the absence of a well‐defined Wilsonian effective action and other related phenomena also appear to rule out such time‐dependent vacua with de Sitter isometries, even in the presence of quantum corrections.

Implications of graviton–graviton interaction to dark matter

Physics Letters B, 2009
Our present understanding of the universe requires the existence of dark matter and dark energy. We describe here a natural mechanism that could make exotic dark matter and possibly dark energy unnecessary. Graviton-graviton interactions increase the gravitational binding of matter.

Photon-graviton pair conversion

, 2004
We consider the conversion of gravitons and photons as a four-wave mixing process. A nonlinear coupled systems of equations involving two gravitons and two photons is obtained, and the energy exchange between the different degrees of freedom is found ...

Decoherence of Gravitational Wave Oscillations in Bigravity

, 2018
Following up on our recent study, we consider the regime of graviton masses and gravitational wave propagation distances at which decoherence of the wave packets plays a major role for phenomenology.
