Structure of charmed baryons studied by pionic decays
Hideko Nagahiro, Shigehiro Yasui, Atsushi Hosaka +2
We investigate the decays of the charmed baryons aiming at the systematic understanding of hadron internal structures based on the quark model by paying attention to heavy quark sy…
Flavor structure of baryons from lattice QCD: From strange to charm quarks
Philipp Gubler, Toru T. Takahashi, Makoto Oka
We study baryons of spin-parity with either a strange or charm valence quark in full 2+1 flavor lattice QCD. Multiple singlet and octet operators ar…
Theoretical study of the Xi(1620) and Xi(1690) resonances in Xi_c -> pi^+ MB decays
Kenta Miyahara, Tetsuo Hyodo, Makoto Oka +2
Nonleptonic weak decays of Xi_c into pi^+ and a meson (M)-baryon (B) final state, MB, are analyzed from the viewpoint of probing S=-2 baryon resonances, i.e. Xi(1620) and Xi(1690),…
Negative-parity nucleon excited state in nuclear matter
Keisuke Ohtani, Philipp Gubler, Makoto Oka
Spectral functions of the nucleon and its negative parity excited state in nuclear matter are studied using QCD sum rules and the maximum entropy method (MEM). It is found that in-…
Understanding the nature of the heavy pentaquarks and searching for them in pion-induced reactions
Xiao-Hai Liu, Makoto Oka
We investigate the reaction via the open-charm hadron rescattering diagrams. Due to the presence of the triangle singularity (TS) in the rescattering amplitude…
Charmed baryons and their interactions
Atsushi Hosaka, Emiko Hiyama, SangHo Kim +7
In this proceedings report, we discuss unique features of charmed, or in general heavy, baryons with one heavy quark. A well and long-term known phenomena, the distinction of the t…
