# Light-Front Spin-1 Model: Parameters Dependence

@article{Mello2015LightFrontSM, title={Light-Front Spin-1 Model: Parameters Dependence}, author={Clayton S. Mello and Anac{\'e} N. da Silva and J.P.B.C. de Melo and Tobias Frederico}, journal={Few-Body Systems}, year={2015}, volume={56}, pages={509-514} }

We study the structure of the ρ-meson within a light-front model with constituent quark degrees of freedom. We calculate electroweak static observables: magnetic and quadrupole moments, decay constant and charge radius. The prescription used to compute the electroweak quantities is free of zero modes, which makes the calculation implicitly covariant. We compare the results of our model with other ones found in the literature. Our model parameters give a decay constant close to the experimental…
