The past decades witnessed the golden era of hadron physics. Many excited open heavy
flavor mesons and baryons have been observed since 2017. We shall provide an updated …

Investigations of deconfined quark matter within NJL-type models are reviewed, focusing on
the regime of low temperatures and “moderate” densities, which is not accessible by …

We explore the properties of quark matter in equilibrium with the weak interactions,
containing comparable numbers of up, down, and strange quarks. Witten has recently …

The application of quark models to the spectra and strong and electromagnetic couplings of
baryons is reviewed. This review focuses on calculations which attempt a global description …

Glueballs are particles whose valence degrees of freedom are gluons and therefore in their
description the gauge field plays a dominant role. We review recent results in the physics of …

In this paper we compute masses and magnetic moments of heavy baryons and tetraquarks
with one and two open heavy flavors in a unified framework of the MIT bag model. Using the …

Using an extended chromomagnetic model, we perform a systematic study of the masses of
doubly heavy tetraquarks. We find that the ground states of the doubly heavy tetraquarks are …

A comprehensive, relativistic many-body approach to hadron structure is advanced based
on the Coulomb gauge QCD Hamiltonian. Dynamical chiral symmetry breaking naturally …

The standard theory of colour forces (QCD) suggests that in addition to the familiar hadrons
made of quarks, there should exist new states where coloured gluons play an essential …

We review the main results obtained in the literature on quasi-normal modes (QNM) of
compact stars and black holes, in the light of recent exciting developments of gravitational …
