Molecular $$\Xi _{bc}$$ Ξbc states from meson–baryon interaction

Autor: Qi-Xin Yu, J. M. Dias, Wei-Hong Liang, E. Oset

Publikováno v: European Physical Journal C: Particles and Fields, Vol 79, Iss 12, Pp 1-13 (2019)

Abstract We have studied the meson–baryon interaction in coupled channels with the same quantum numbers of $$\Xi _{bc}$$ Ξbc . The interaction is attractive in some channels and of sufficient intensity to lead to bound states or resonances. We use

Masses of doubly heavy baryons in the Bethe-Salpeter equation approach

Autor: Qi-Xin Yu, Xin-Heng Guo

Publikováno v: Nuclear Physics B, Vol 947, Iss , Pp - (2019)

A doubly heavy baryon can be regarded as composed of a heavy diquark and a light quark. In this picture, we study the masses of the doubly heavy diquarks in the Bethe-Salpeter (BS) formalism first, which are then used as one of the inputs in studying

Two-band description of the strong `spin'-orbit coupled one-dimensional hole gas in a cylindrical Ge nanowire

Autor: Li, Rui, Qi, Xin-Yu

Publikováno v: J. Phys.: Condens. Matter 35, 135302 (2023)

The low-energy effective Hamiltonian of the strong `spin'-orbit coupled one-dimensional hole gas in a cylindrical Ge nanowire in the presence of a strong magnetic field is studied both numerically and analytically. Basing on the Luttinger-Kohn Hamilt
