摘要Hadronic states composed of multi-quark flavors may exist in reality since they are not prohibited by quantum chromodynamics (QCD). Compact four-quark systems of a color singlet are classified as tetraquarks. To understand the properties of these states, more theoretical and experimental efforts are needed. In this work, we study charmed tetraquarks with three light flavors using flavor SU(3) symmetry. States with three different light quarks must be in a (6) over bar or a 15 multiplet. We investigate the production of charmed tetraquarks X-c in B -> X-c((X) over bar (c)) P and B-c -> XcP decays. Whether the states with three light quarks belong to (6) over bar or 15 can be determined by studying various tetraquark B and Bc decays. We demonstrate that the decay amplitudes for these decays can be parametrized by a few irreducible SU(3) invariant amplitudes. We then derive relations for decay widths and charge-parity-violating rate difference, which can be examined experimentally. Although no experimental measurements are available yet, they might be accessed at the ongoing and forthcoming experiments such as LHCb and Belle-II. Measurements of these observables can not only provide useful information for the study of exotics spectroscopy but also provide valuable information towards a better understanding of some non-perturbative aspects of QCD.
