Analyticity, Unitarity and One-loop Graviton Corrections to Compton Scattering
Hovhannes R. Grigoryan
We compute spin-flip cross section for graviton photoproduction on a spin-1/2 target of finite mass. Using this tree-level result, we find one-loop graviton correction to the spin-…
New Sum Rules from Low Energy Compton Scattering on Arbitrary Spin Target
Hovhannes R. Grigoryan, Massimo Porrati
We derive two sum rules by studying the low energy Compton scattering on a target of arbitrary (nonzero) spin j. In the first sum rule, we consider the possibility that the interme…
Gravity Dual Corrections to the Heavy Quark Potential at Finite-Temperature
Hovhannes R. Grigoryan, Yuri V. Kovchegov
We apply gauge/gravity duality to compute corrections to the heavy quark potentials of a quark--anti-quark pair () and of a quark--quark pair () immersed int…
Long-Range Rapidity Correlations in Heavy Ion Collisions at Strong Coupling from AdS/CFT
Hovhannes R. Grigoryan, Yuri V. Kovchegov
We use AdS/CFT correspondence to study two-particle correlations in heavy ion collisions at strong coupling. Modeling the colliding heavy ions by shock waves on the gravity side, w…
Towards the Gravity Dual of Quarkonium in the Strongly Coupled QCD Plasma
Hovhannes R. Grigoryan, Paul M. Hohler, Mikhail A. Stephanov
We build a "bottom-up" holographic model of charmonium by matching the essential spectral data. We argue that this data must include not only the masses but also the decay constant…
Photoproduction through Chern-Simons Term Induced Interactions in Holographic QCD
S. K. Domokos, H. R. Grigoryan, J. A. Harvey
We employ both top-down and bottom-up holographic dual models of QCD to calculate vertex functions and couplings that are induced by the five dimensional Chern-Simons term. We use…
