Unitarization of infinite-range forces: graviton-graviton scattering

open access: yesJournal of High Energy Physics, 2022
A method to unitarize the scattering amplitude produced by infinite-range forces is developed and applied to Born terms. In order to apply S-matrix techniques, based on unitarity and analyticity, we first derive an S-matrix free of infrared divergences ...

Classifying and constraining local four photon and four graviton S-matrices [PDF]

open access: yesJournal of High Energy Physics, 2019
We study the space of all kinematically allowed four photon and four graviton S-matrices, polynomial in scattering momenta. We demonstrate that this space is the permutation invariant sector of a module over the ring of polynomials of the Mandelstam ...

State-dependent graviton noise in the equation of geodesic deviation [PDF]

open access: yes, 2020
We consider an equation of the geodesic deviation appearing in the problem of gravitational wave detection in an environment of gravitons. We investigate a state-dependent graviton noise (as discussed in a recent paper by Parikh,Wilczek and Zahariade ...

Thermal Giant Graviton with Non-commutative Dipole Field

open access: yes, 2007
Using the type II near-extremal 3D-branes solution we apply the T-duality and smeared twist to construct the supergravity backgrounds which dual to the 4D finite temperature non-commutative dipole field theories.

Simulation of Z plus Graviton/Unparticle Production at the LHC [PDF]

open access: yes, 2008
Theories with extra dimensions have gained much interest in recent years as candidates for a possible extension of the SM. The observation of large extra dimensions through real graviton emission is one of the most popular related new phenomena. The main

Non-Abelian giant gravitons [PDF]

open access: yesClassical and Quantum Gravity, 2003
We argue that the giant graviton configurations known from the literature have a complementary, microscopical description in terms of multiple gravitational waves undergoing a dielectric (or magnetic moment) effect. We present a non-Abelian effective action for these gravitational waves with dielectric couplings and show that stable dielectric ...

Graviton Physics: A Concise Tutorial on the Quantum Field Theory of Gravitons, Graviton Noise, and Gravitational Decoherence

open access: yesUniverse
The detection of gravitational waves in 2015 ushered in a new era of gravitational wave (GW) astronomy capable of probing the strong field dynamics of black holes and neutron stars.

Entanglement and mixed states of Young tableau states in gauge/gravity correspondence

open access: yesNuclear Physics B, 2021
We use entangled multimode coherent states to produce entangled giant graviton states, in the context of gauge/gravity duality. We make a smeared distribution of the entangled multimode coherent states on the circle, or on the five-sphere, in the higher ...

Dual Identities inside the Gluon and the Graviton Scattering Amplitudes [PDF]

open access: yes, 2010
Recently, Bern, Carrasco and Johansson conjectured dual identities inside the gluon tree scattering amplitudes. In this paper, we use the properties of the heterotic string and open string tree scattering amplitudes to refine and derive these dual ...
