95. Likely existence of bound states and the Efimov effect in the triple-$J/\psi$ system

Ya-Wen Pan

Oral+Poster

The ground-breaking discovery of the first fully charmed
tetraquark state $X(6900)$ in the $J/\psi J/\psi$ invariant mass
distribution by the LHCb collaboration has inspired intensive
theoretical studies. Various interpretations, such as molecular
states, compact tetraquark states, and coupled-channel effects, have
been proposed for these states. Of particular interest is the...

96. Measurement of neutron-induced fission cross sections and migration effect of gaseous fission product in MSR

Bolin Fu (Shanghai Institute of Applied Physics (SINAP), CAS)

Poster only

As only one of the six candidate reactor types for Generation IV nuclear power systems that adopts liquid fuel, Molten Salt Reactor (MSR) has aroused growing attention worldwide and characterized by the following advantages: 1) MSR adopts the liquid fuel and is characterized by high temperature and low pressure during the operation and water-free cooling, leading the higher inherent safety. 2)...

98. Model calculation of Ue

Jiayinghao Li

Poster only

Due to the exist of electrons around the target atom, the effect c. m. energy in experient is larger than that of bare nuclei system. The larger part Ue is the absolute value of the potential between the projectile and electrons is Ue. In the energy region of astrophysical interest, Ue has a significant imoact on cross section. However, Ue got by ananlyzing experiment data is usually large...

97. Quantum mechanical softening of hypertriton

Daineng Liu

Poster only

Understanding the properties of hypernuclei helps to constrain the interaction between hyperon and nucleon, which is known to play an essential role in determining the properties of neutron stars. Experimental measurements have suggested that the hypertriton (${}_{\mathrm{\Lambda }}^3\text{H}$), the lightest hypernucleus, exhibits a halo structure with a deuteron core encircled by a $\mathrm{\Lambda }$ hyperon at a...

99. Relativistic Brueckner-Hartree-Fock theory with in-medium baryon-baryon interaction

Ruyou Zheng

Poster only

The in-medium baryon-baryon(BB) interaction plays an important role in nuclear physics and nuclear astrophysics. Recently, the relativistic Brueckner-Hartree-Fock (RBHF) framework with the leading order covariant chiral nucleon-nucleon interaction successfully reproduces the saturation of the symmetric nuclear matter. RBHF theory with the leading order covariant chiral BB interaction is...

94. Two-body hadronic weak decays of bottomed hadrons

Ying Zhang

Oral+Poster

The structure of light diquarks plays a crucial role in the formation of exotic hadrons beyond the conventional quark model, especially in their line shapes of bottomed hadron decays. We study the two-body hadronic weak decays of bottomed baryons and bottomed mesons to probe the light diquark structure and pin down the quark-quark correlations in the diquark picture. We find that the light...
