Spin splittings among charmed hadrons

TL;DR

This paper compares spin-induced mass splittings in charmed hadrons across lattice simulations, quark models, and experimental data, providing insights into heavy quark symmetry and hadron structure.

Contribution

It presents lattice simulation results for charmed hadron mass splittings using an improved anisotropic action, comparing them with models and experimental data.

Findings

Lattice results align with heavy quark symmetry predictions.

Mass splittings are consistent with quark model estimates.

Results contribute to understanding spin effects in charmed hadrons.

Abstract

The mass differences between spin-1/2 and spin-3/2 baryons are compared to the mass differences between spin-0 and spin-1 mesons. Results of simulations for charmed hadrons in the quenched approximation from a tadpole-improved anisotropic action are discussed in the context of other lattice calculations, quark model predictions, heavy quark symmetry predictions and experimental data.
