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 …

A large number of experimental discoveries especially in the heavy quarkonium sector that
did not meet the expectations of the until then very successful quark model led to a …

In the past two decades, a plethora of hadronic states beyond the conventional quark model
of qq ̄ mesons and qqq baryons have been observed experimentally, which motivated …

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 calculate the properties of excited charm and charm-strange mesons. We use the
relativized quark model to calculate their masses and wave functions that are used to …

The B-factories and Large Hadron Collider experiments have demonstrated the ability to
observe and measure the properties of bottomonium mesons. In order to discover missing …

We revisit the bottomonium spectrum motivated by the recently exciting experimental
progress in the observation of new bottomonium states, both conventional and …

A bstract In two recent papers, we used the hadro-quarkonium model to study the properties
of hidden-charm and bottom tetraquarks and pentaquarks. Here, we extend the previous …

We study the mass spectra and radiative decays of doubly heavy baryons within the diquark
picture in a relativized quark model. The mass of the JP= 1/2+ Ξ cc ground state is predicted …
