Since 2003, many hadrons that do not fit into the conventional quark model of qqbar mesons and qqq baryons have been discovered experimentally. Because most (if not all) of these states are located at the thresholds of a pair of conventional hadrons, they have been conjectured to be hadronic molecules. There have been extensive theoretical and experimental studies to verify or refute the...

Some hadrons are hard to explain as normal hadrons made of quarks and antiquarks, or three quarks. These are called exotic hadrons. Since the Belle experiment reported $X(3872)$ in 2003, more exotic hadrons containing charm quarks have been found. Exotic hadrons are believed to have more complex structures than normal hadrons, but no conclusion has been reached yet.
The $X(3872)$ is one of...

Exotic hadrons are important subjects in the hadron physics. These states which lie slightly below the threshold have been expected to be hadronic molecules of two ordinary hadrons.
$T_{cc}$ was reported by the LHCb experiment in 2022 and this state is consistent with an isoscalar state whose $J$-parity is $1^+$. The Breit-Wigner mass relative to the $D^{\ast +}D^0$ threshold is...

In this presentation, we explore the low-energy behavior of $DD^*$ scattering phase shifts using twisted boundary conditions. While Lüscher’s method is typically employed to calculate scattering phase shifts between two hadrons from energy spectra, it becomes impractical to achieve high-resolution results using only periodic boundary conditions due to volume limitations. Conversely, twisted...

The properties of QCD matter in a strong magnetic field have attracted much attention because of their relevance to the physics of relativistic heavy-ion collisions and magnetars. For example, the effects of magnetic fields are intensely studied in both single-body and many-body problems, such as modifications of the hadron mass spectrum and the QCD phase diagram. On the other hand, recent...

We firstly employ the novel lattice EFT method to multi-hadron systems. The $DD^*K$ three-body system is taken as an illustration to demonstrate the great power of lattice EFT to hadron physics, especially the potential application for many-body systems. The sub two-body interactions are fixed by the $T_{cc}^+$, $D^{\ast}_{s0}(2317)$ and $D_{s1}(2460)$ states.

In this study, we present a lattice QCD analysis of the $J^P=1^+$
diquark within the charmed baryon $Σ_c^{++}(uuc)$.Treating $Σ_c$ as a bound state of a charm quark and a uu $1^+$ diquark,
we utilize an extended HAL QCD potential method to determine both the
mass of the $1^+$ diquark and the potential between the charm quark and
the $1^+$ diquark.Unlike the standard HAL...

New measurements of the weak charge density distributions of $^{48}$Ca and $^{208}$Pb challenge existing nuclear models. In the post-PREX-CREX era, it is unclear if current models can simultaneously describe weak charge distributions along with accurate measurements of binding energy and charge radii. In this letter, we explore the parameter space of relativistic and non-relativistic models to...

We present the results of using the homotopy method to solve the nonlinear evolution equation for diffractive production in deep inelastic scattering (DIS). Initially, we introduce part of the nonlinear corrections as the first step in this approach. This allows for an analytical solution to the simplified nonlinear evolution equation, taking into account the initial and boundary conditions....
