Chiral symmetry and its spontaneous breaking play an important role both in the light
hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …

Over the last decade, numerical solutions of Quantum Chromodynamics (QCD) using the
technique of lattice QCD have developed to a point where they are beginning to connect …

We explore the possibility that dark matter (DM) is the lightest hadron made of two stable
color octet Dirac fermions Q. The cosmological DM abundance is reproduced for MQ≈ 12.5 …

We investigate the mass spectra of molecular-type hexaquark states in the dibaryon
systems. These systems are composed of the charmed baryons [Σ c (*), Ξ c (′,*)], doubly …

In recent years, nuclear physics has benefited greatly from the development of powerful ab
initio many-body methods and their combination with interactions from chiral effective field …

We calculate the scattering cross section between two 0++ glueballs in SU (2) Yang-Mills
theory on a lattice at β= 2.1, 2.2, 2.3, 2.4, and 2.5 using the indirect (HAL QCD) method. We …

We report the first lattice QCD study of the heavy dibaryons in which all six quarks have the
bottom (beauty) flavor. Performing a state-of-the-art lattice QCD calculation we find clear …

In the framework of a one-boson-exchange model, we carry out a comprehensive
investigation of the Ξ c N/Λ c Σ/Ξ c′ N/Σ c Λ/Ξ c* N/Σ c* Λ/Σ c Σ/Σ c* Σ interactions. We …

Inspired by the recent discovery of the doubly charmed tetraquark state T cc+ by the LHCb
Collaboration, we perform a systematic study of masses and strong decays of open charm …
