Squeezed-state radiation in shockwave scattering: QCD-Gravity double copy
Anna M. StaÅto, Himanshu Raj, Raju Venugopalan
Gluon and graviton radiation in strong field shockwave scattering are described by effective Lipatov vertices, with the graviton Lipatov vertex proportional to the bilinear of its…
QCD-Gravity double copy in Regge asymptotics: from amplitudes to radiation in shockwave collisions
Himanshu Raj, Raju Venugopalan
These lectures discuss multi-particle production in QCD and in gravity at ultrarelativistic energies, their double copy relations, and strong parallels in emergent shockwave dynami…
QCD-Gravity double-copy in the Regge regime: shock wave propagators
Himanshu Raj, Raju Venugopalan
In recent work, we demonstrated a double-copy relation between inclusive gluon radiation in shock wave collisions of ultrarelativistic nuclei and inclusive graviton radiation in tr…
Gravitational wave double copy of radiation from gluon shockwave collisions
Himanshu Raj, Raju Venugopalan
In a recent paper, we showed that the gravitational wave spectrum from trans-Planckian shockwave scattering in Einstein gravity is determined by the gravitational Lipatov vertex ex…
