Two-nucleon systems at $m_{π} \approx 292$ MeV from lattice QCD

Kuan Zhang, Kang Yu, Yiqi Geng +5

Nucleon-nucleon systems in the $^{3} S_{1}$ and the $^{1} S_{0}$ channels are studied in lattice quantum chromodynamics at a pion mass of approximately $m_{π} \approx 292$ MeV, employing three $…

Parton Distribution Function of a Deuteron-like Dibaryon System from Lattice QCD

Chen Chen, Liuming Liu, Peng Sun +5

We report a lattice QCD calculation of the parton distribution function (PDF) of a deuteron-like dibaryon system using large-momentum effective theory. The calculation is done on t…

Lattice QCD study of $I^_{c} I^_{c}$ scattering

Hanyang Xing, Yiqi Geng, Chuan Liu +5

We present the first lattice result of the near threshold $I^_{c} I^_{c}$ scattering with $I (J^{P}) = 0 (0^{+})$ . The calculation is performed on two $N_{f} = 2 + 1$ Wilson-Clover ensembles with…

Polarization and quantum entanglement effects in $B_{c}^{\pm} \to J / I ¨ + I ¨ ^{\pm} + I ¨ ^{0}$ process

Kaiwen Chen, Yiqi Geng, Yichao Jin +2

Motivated by the very recent observation of the $B_{c}^{+} \to J / I ¨ + I ¨ ^{+} + I ¨ ^{0}$ decay using proton-proton collision data by the LHCb collaboration, we study the four-body angular distri…
