X(3872) revisited: the roles of OPEP and the quark degrees of freedom

Sachiko Takeuchi, Yasuhiro Yamaguchi, Atsushi Hosaka +1

The $X (3872)$ is investigated by employing the quark-hadron hybrid model, that consists of the $c c ˉ$ core, $D^{(*)} D ˉ^{*}$ , $J / ψ ω$ , and $J / ψ ρ$ two-meson states. Due to the…

The impact of quark many-body effects on exotic hadrons

Sachiko Takeuchi, Makoto Takizawa, Yasuhiro Yamaguchi +1

We investigate the exotic hadrons consisting of two light quarks and two heavy antiquarks, $(q Q ˉ)$ - $(q Q ˉ)$ . The spin-dependent term between quarks is known to give an attra…

Substructure of Multiquark Hadrons (Snowmass 2021 White Paper)

Nora Brambilla, Hua-Xing Chen, Angelo Esposito +27

In recent years there has been a rapidly growing body of experimental evidence for existence of exotic, multiquark hadrons, i.e. mesons which contain additional quarks, beyond the…

Search for $B^{0} \to K_{S}^{0} K_{S}^{0} γ$ decays at Belle

Belle Collaboration, H. B. Jeon, K. H. Kang +219

We report the first search for the penguin-dominated process $B^{0} \to K_{S}^{0} K_{S}^{0} γ$ using the full data sample of $772 \times 1 0^{6}$ $B B ˉ$ pairs collected with the Bell…

Search for a light Higgs boson in single-photon decays of $Υ (1 S)$ using $Υ (2 S) \to π^{+} π^{-} Υ (1 S)$ tagging method

Belle Collaboration, S. Jia, C. P. Shen +210

We search for a light Higgs boson ( $A^{0}$ ) decaying into a $τ^{+} τ^{-}$ or $μ^{+} μ^{-}$ pair in the radiative decays of $Υ (1 S)$ . The production of $Υ (1 S)$ mesons is tagged by $Υ(2S)\to π^+…

Search for tetraquark states $X_{cc s ˉ s ˉ}$ in $D_{s}^{+} D_{s}^{+} (D_{s}^{+} D_{s}^{+})$ final states at Belle

Belle Collaboration, X. Y. Gao, Y. Li +206

A search for double-heavy tetraquark state candidates $X_{cc s ˉ s ˉ}$ decaying to $D_{s}^{+} D_{s}^{+}$ and $D_{s}^{*+} D_{s}^{*+}$ is presented for the first time using the…
