AdS/CFT integrability and light-front dynamics in a semiclassical approximation to QCD
Seminar Room 1, Newton Institute
We derive light-front equations for the bound states of massless quarks from the semiclassical approximation to the equations of motion describing the propagation of bosonic and fermionic modes on AdS space and the mapping of string modes to light-front wavefunctions of hadrons in physical space-time. The effective equations describing light-front eigenmodes in 3+1 space-time depend on the average impact distance between the constituents and possesses remarkable algebraic structures and integrability properties dictated by the conformality of the theory. The holographic model is extended to include a confining potential while preserving its algebraic structure. The gauge/gravity correspondence provides insights into inherently non-perturbative aspects of hadronic physics, such as the orbital and radial spectra and the behavior of form factors in the space-like and the time-like regions.
