UConn Physics Colloquium

Proton-Proton Elastic Scattering at the Large Hadron Collider and Nucleon Structure

Professor M. Munir Islam
Department of Physics
University of Connecticut

High energy elastic pp differential cross section at the Large Hadron Collider (LHC) at center of mass energy 14 TeV is predicted using the asymptotic behavior of total cross section, ratio of real / imaginary amplitude in the forward direction, and the measured pp differential cross section at c.m. energy 546 GeV. The phenomenological investigation has progressively led us to an effective field theory model that describes the nucleon as a chiral bag embedded in a quark-antiquark condensed ground state. The measurement of pp elastic scattering up to large momentum transfer at LHC by the TOTEM (Total and Elastic Measurement ) group will be crucial to test this structure of the nucleon.
