UW - 01 - 17 Light Front Nuclear Theory
High energy scattering experiments involving nuclei are typically analyzed in terms of light front variables. The desire to provide realistic, relativistic wave functions expressed in terms of these variables led me to try to use light front dynamics to compute nuclear wave functions. Here calculations of infinite nuclear matter in the mean field approximation and also in a light front version ...
متن کاملLight Front Nuclear Theory and the HERMES Effect
I discuss applications of relativistic light front dynamics (the use of light cone variables) to computing the nucleonic and mesonic components of nuclear wave functions. Our method is to use a Lagrangian and its associated energy-momentum tensor T μ to define the total momentum operators Pμ, with P+ as the plus-momentum and P the light cone time development operator. The aim of this unusual ap...
متن کاملRotational Invariance In Nuclear Light-Front Mean Field Theory
A light-front treatment for spherical nuclei is developed from a relativistic effective Lagrangian and employing the mean field approximation. Minimizing the nuclear minus momentum subject to the constraint that, in the rest frame, the expectation values of the plusand minus-momenta are the same leads to a formalism in which rotational invariance is recovered. Light cone variables have long bee...
متن کاملLight-Front Nuclear Physics: Mean Field Theory for Finite Nuclei
A light-front treatment for finite nuclei is developed from a relativistic effective Lagrangian (QHD1) involving nucleons, scalar mesons and vector mesons. We show that the necessary variational principle is a constrained one which fixes the expectation value of the total momentum operator P+ to be the same as that for P−. This is the same as minimizing the sum of the total momentum operators: ...
متن کاملHadrons in the Nuclear Medium- Role of Light Front Nuclear Theory
The problem of understanding the nuclear effects observed in lepton-nucleus deepinelastic-scattering (the EMC effect) is still with us. Standard nuclear models (those using only hadronic degrees of freedom) are not able to account for the EMC effect. Thus it is necessary to understand how the nuclear medium modifies quark wave functions in the nucleus. Possibilities for such modifications, repr...
