Abstract The standard picture of light front dynamics employs the null plane ct + z = 0; whereas the new picture employs a set of null planes ξ · x = 0, where ξ is a lightlike vector. The state vectors and operators in the new picture, also called the ξ-picture, are related to the state vectors and operators in the standard picture by a unitary transformation which depends on the unit vector u = − ξ /| ξ |, where ξ is the three-vector part of ξ. The new picture provides a formalism for dealing… CONTINUE READING
