Construction of an asymptotic S matrix for perturbative quantum gravity
John Ware, Ryo Saotome, Ratindranath Akhoury
The infrared behavior of perturbative quantum gravity is studied using the method developed for QED by Faddeev and Kulish. The operator describing the asymptotic dynamics is derive…
High Energy Scattering in Perturbative Quantum Gravity at Next to Leading Power
Ratindranath Akhoury, Ryo Saotome, George Sterman
We consider the relativistic scattering of unequal-mass scalar particles through graviton exchange in the small-angle high-energy regime. We show the self-consistency of expansion…
Relationship Between Gravity and Gauge Scattering in the High Energy Limit
Ryo Saotome, Ratindranath Akhoury
Investigations of high-energy graviton-graviton and gluon-gluon scattering are performed in the leading eikonal approximation for the kinematic regime of large center of mass energ…
No Classicalization Beyond Spherical Symmetry
Ratindranath Akhoury, Shinji Mukohyama, Ryo Saotome
We point out that a field theory that exhibits the classicalization phenomenon for perfect spherical symmetry ceases to do so when the spherical symmetry is significantly relaxed.…
Collinear and Soft Divergences in Perturbative Quantum Gravity
Ratindranath Akhoury, Ryo Saotome, George Sterman
Collinear and soft divergences in perturbative quantum gravity are investigated to arbitrary orders in amplitudes for wide-angle scattering, using methods developed for gauge theor…
Non-Stationary Dark Energy Around a Black Hole
Ratindranath Akhoury, David Garfinkle, Ryo Saotome +1
Numerical simulations of the accretion of test scalar fields with non-standard kinetic terms (of the k-essence type) onto a Schwarzschild black hole are performed. We find a full d…
