Large CP violation in charmed baryon decays
We present a systematic numerical study of CP violation in two-body weak decays of antitriplet charmed baryons. In the standard model, the $Δc =1$ quark level interactions inducing CP violation for the relevant decays can be grouped into two types, proportional to the CKM matrix elements $λ_q= V_{uq}V^*_{cq}$ with $q=d$ and $q=b$, respectively. Recent studies have shown that with $SU(3)_F$ flavor symmetry, the decay amplitudes, including their strong phases, can be determined by data if contr…

Hidden-flavour four-quark states in the charm and bottom region
We discuss the spectrum and the internal composition of ground and excited four-quark states in the charm and bottom energy region. To this end we extend previous calculations within the framework of the relativistic four-body Faddeev-Yakubovsky equation to include quantum numbers with $J^{P C} = 0^{++} , 0^{-+} , 1^{--} , 1^{+-}$ and $1^{+ +}$ and study their internal composition in terms of heavy-light meson pairs, hadroquarkonia and diquark-antidiquark clusters. We observe similar patterns i…

Bound isoscalar axial-vector $bc\bar u\bar d$ tetraquark $T_{bc}$ from lattice QCD using two-meson and diquark-antidiquark variational basis
We report a lattice QCD study of the heavy-light meson-meson interactions with an explicitly exotic flavor content $bc\bar u\bar d$, isospin $I\!=\!0$, and axialvector $J^P=1^+$ quantum numbers in search of possible tetraquark bound states. The calculation is performed at four values of lattice spacing, ranging $\sim$0.058 to $\sim$0.12 fm, and at five different values of valence light quark mass $m_{u/d}$, corresponding to pseudoscalar meson mass $M_{ps}$ of about 0.5, 0.6, 0.7, 1.0, and 3.0 G…
