$X$ and $Z_{cs}$ in $B^{+} \to J / ψ ϕ K^{+}$ as $s$ -wave threshold cusps and alternative spin-parity assignments to $X (4274)$ and $X (4500)$

Xuan Luo, Satoshi X. Nakamura

Recent LHCb's amplitude analysis on $B^{+} \to J / ψ ϕ K^{+}$ suggests the existence of exotic $X$ and $Z_{cs}$ hadrons, based on an assumption that Breit-Wigner resonances describe all the…

Multiplier Hermitian-Einstein metrics on Fano manifolds of KSM-type

Yasuhiro Nakagawa, Satoshi Nakamura

In this article we focus on multiplier Hermitian-Einstein metrics introduced by Mabuchi which include Kähler-Einstein metrics, Kähler-Ricci solitons and Mabuchi solitons as special…

$X$ structures in $B^{+} \to J / ψ ϕ K^{+}$ as one-loop and double-triangle threshold cusps

Satoshi X. Nakamura

The LHCb data on $B^{+} \to J / ψ ϕ K^{+}$ show four peaks and three dips in the $J / ψ ϕ$ invariant mass distribution, and the peaks are interpreted as $X (4140)$ , $X (4274)$ , $X (4500)$ and $X(…

Novel description of $P_{c} (4312)^{+}$ , $P_{c} (4380)^{+}$ , and $P_{c} (4457)^{+}$ with double triangle cusps

Satoshi X. Nakamura

We propose a novel scenario for the peak structures, usually interpreted as hidden charm pentaquark ( $P_{c}$ ) contributions, in the LHCb's $Λ_{b}^{0} \to J / ψ p K^{-}$ data. The key idea is t…

An $X (3872)$ -like peak in $B \to (J / ψ π^{+} π^{-}) K π$ due to triangle singularity

Satoshi X. Nakamura

Triangle mechanisms for $B^{0} \to (J / ψ π^{+} π^{-}) K^{+} π^{-}$ are studied. Experimentally, an $X (3872)$ peak has been observed in this process. When the final $(J / ψ π^{+} π^{-}) π$ invariant mass i…

$P_{c} (4312)^{+}$ , $P_{c} (4380)^{+}$ , and $P_{c} (4457)^{+}$ as double triangle cusps

Satoshi X. Nakamura

Understanding the nature of the hidden charm pentaquark(like) signals in the LHCb data for $Λ_{b}^{0} \to J / ψ p K^{-}$ is a central problem of hadron spectroscopy. We propose a scenario co…
