# Electroexcitation of nucleon resonances of the [70,1-] multiplet in a light-front relativistic quark model

## TL;DR

This paper uses a light-front relativistic quark model to predict the core contributions to the electroexcitation of specific nucleon resonances, aiding interpretation of upcoming experimental data in the third resonance region.

## Contribution

It provides theoretical predictions for nucleon resonance electroexcitation amplitudes, distinguishing quark core effects from meson-baryon contributions, especially relevant for upcoming CLAS experiments.

## Key findings

- Quantified meson-baryon contributions to electroexcitation amplitudes.
- Predicted core contributions for N(1520)3/2-, N(1535)1/2-, and N(1675)5/2-.
- Provided Q2-dependent electroexcitation amplitude estimates.

## Abstract

We utilize a light-front relativistic quark model to predict the 3q core contribution to the electroexcitation of nucleon resonances of the [70,1-] multiplet on the proton and neutron at Q2 < 5GeV2. The investigation is stimulated in large degree by expected progress in the studies of the electroexcitation of nucleon resonances in the third resonance region in the CLAS experiment. For the resonances N(1520)3/2-, N(1535)1/2-, and N(1675)5/2-, experimental data on electroexcitation amplitudes on the proton are available in a wide range of Q2. This allowed us to quantify the expected meson-baryon contributions to these amplitudes as a function of Q2.
