Multi-particle production and asymptotic behavior of scattering amplitudes at high energy in scalar theory
Presented by Dr. Mikhail GORSHTEYN on 3 Jun 2013 from 8:50 AM to 9:10 AM
Session: Morning Session - VII
We study asymptotic behavior of 2$\to$2 scattering amplitudes at high energy and low momentum transfer. We consider massive scalar $\lambda\phi^3$-theory and a scalar theory with vector exchanges in the ladder approximation (multi-particle production in the intermediate state). We discuss in particular the kinematics of "real Compton scattering", elastic "virtual Compton scattering" (DIS), and asymmetric "virtual Compton scattering" (DVCS).
