The quark model was formulated in 1964 to classify mesons as bound states made of a
quark–antiquark pair, and baryons as bound states made of three quarks. For a long time all …

Using a relativized diquark model Hamiltonian, we calculate the masses of J^ PC= 0^++ J
PC= 0++ ground-state tetraquarks in the following systems: bs ̄ b ̄ s bsb¯ s¯, bb ̄ n ̄ n …

We discuss the nature of the χ b (3 P) and X (3872) mesons. Are the χ b (3 P)'s standard bb¯
mesons or bb¯ states with a significative continuum component? Is the X (3872) acc¯ state …

We present a quark model calculation of the charmonium spectrum with self-energy
corrections due to the coupling to the meson-meson continuum. The bare masses used in …

We show the results of a coupled-channel quark model calculation of the bottomonium
spectrum with self-energy corrections due to the coupling to the meson-meson continuum …

Strange and nonstrange baryon spectra in the relativistic interacting quark-diquark model with a

We calculate the spectrum of qq¯ cc¯ and ss¯ cc¯ tetraquarks, where q, s, and c stand for
light (u, d), strange, and charm quarks, respectively, in a relativized diquark model …

We make a systematic calculation of the spectra and hadronic decays of the D s system in a
coupled channel framework, where the unquenched effects are induced by the P 0 3 model …

Recently, the experimental results of the LHCb Collaboration suggested the existence of five
new excited states of Ω c 0: Ω c (3000) 0, Ω c (3050) 0, Ω c (3066) 0, Ω c (3090) 0, and Ω c …

Inspired by the five newly observed Ω c 0 states by the LHCb detector, we study the Ω c 0
states as the S-wave molecular pentaquarks with I= 0, JP= 1 2-, 3 2-, and 5 2-by solving the …
