Thomas Gutsche, Valery E. Lyubovitskij, Ivan Schmidt, Alfredo Vega

摘要:

本文讨论了一个描述具有可调量子数n,J,L,S的介子和重子的全息软壁模型。这种方法是基于一个行动,它描述了强子与破共形不变性,并通过一个背景场的存在下,结合禁闭。得到的重-轻介子质量和衰变常数的结果是一致的HQET的预测。在重子扇区中,讨论了重子质量、核子电磁形状因子和广义部分子分布。

英文摘要:

We discuss a holographic soft-wall model developed for the description of mesons and baryons with adjustable quantum numbers n, J, L, S. This approach is based on an action which describes hadrons with broken conformal invariance and which incorporates confinement through the presence of a background dilaton field. Results obtained for heavy-light meson masses and decay constants are consistent with predictions of HQET. In the baryon sector applications to the baryon masses, nucleon electromagnetic form factors and generalized parton distributions are discussed.
