Revising the $f_{1} (1420)$ resonance

V. R. Debastiani, F. Aceti, Wei-Hong Liang +1

We have studied the production and decay of the $f_{1} (1285)$ into $π a_{0} (980)$ and $K^{*} K ˉ$ as a function of the mass of the resonance and find a shoulder around 1400 MeV, tied t…

Semileptonic $Λ_{b} \to ν ˉ_{l} l Λ_{c} (2595)$ and $Λ_{b} \to ν ˉ_{l} l Λ_{c} (2625)$ decays in the molecular picture of $Λ_{c} (2595)$ and $Λ_{c} (2625)$

Wei-Hong Liang, Eulogio Oset, Zhu-Sheng Xie

We evaluate the partial decay widths for the semileptonic $Λ_{b} \to ν ˉ_{l} l Λ_{c} (2595)$ and $Λ_{b} \to ν ˉ_{l} l Λ_{c} (2625)$ decays from the perspective that these two $Λ_{c}^{*}$ reson…

The Peak Structure in the In-Flight $^{3} He (K^{-}, Λ p) n$ Reaction Around the $K ˉ N N$ Threshold

Takayasu Sekihara, Eulogio Oset, Angels Ramos

We theoretically investigate the origin of the peak structure around the $K^{-} pp$ threshold observed in the in-flight $^{3} He (K^{-}, Λ p) n$ reaction in the recen…

$Λ_{b} \to π^{-} (D_{s}^{-}) Λ_{c} (2595), π^{-} (D_{s}^{-}) Λ_{c} (2625)$ decays and $D N, D^{*} N$ molecular components

Wei-Hong Liang, Melahat Bayar, Eulogio Oset

From the perspective that the $Λ_{c} (2595)$ and $Λ_{c} (2625)$ are dynamically generated resonances from the $D N, D^{*} N$ interaction and coupled channels, we have evaluated the rates for…

$f_{2} (1810)$ as a triangle singularity

Ju-Jun Xie, Li-Sheng Geng, Eulogio Oset

We perform calculations showing that a source producing $K^{*} K ˉ^{*}$ in $J = 2$ and $L = 0$ gives rise to a triangle singularity at $1810$ MeV with a width of about $200$ MeV from…

Role of a triangle singularity in the $γ p \to K^{+} Λ (1405)$ reaction

En Wang, Ju-Jun Xie, Wei-Hong Liang +2

We show the effects of a triangle singularity mechanism for the $γ p \to K^{+} Λ (1405)$ reaction. The mechanism has a $N^{*}$ resonance around 2030 MeV, which decays into $K^{*} Σ$ . The $K…
