Exotic hadrons associated with $b$ -quark

Xinchen Dai, Sen Jia, Alexey Nefediev +3

Compared to charmonium-like states, exotic hadrons associated with $b$ -quark offer distinct advantages for exploring the nature of multiquark phenomena and the dynamics of the stro…

$B ˉ_{s} \to K$ semileptonic decay from an Omnès improved nonrelativistic quark model

C. Albertus, E. Hernández, C. Hidalgo-Duque +1

We study the $f^{+}$ form factor for the $B ˉ_{s} \to K^{+} ℓ^{-} ν ˉ_{ℓ}$ semileptonic decay in a nonrelativistic quark model. The valence quark contribution is supplemented with a…

$B \to ρ$ semileptonic decays and $∣ V_{u b} ∣$

C. Albertus, E. Hernández, J. Nieves

We reevaluate the $B \to ρ l^{+} ν_{l}$ decay width as a full $B \to π π l^{+} ν_{l}$ four-particle decay, in which the two final pions are produced via an intermediate $ρ$ meson. The decay wid…

Exclusive $c \to s, d$ semileptonic decays of spin-1/2 and spin-3/2 $c b$ baryons

C. Albertus, E. Hernandez, J. Nieves

We present results for exclusive semileptonic decay widths of ground state spin- $1/2$ and spin- $3/2$ $c b$ baryons corresponding to a $c \to s, d$ transition at the quark level. The…

$ΛΛ$ interaction and hypernuclei

C. Albertus, J. E. Amaro, J. Nieves

Data on $ΛΛ$ hypernuclei provide a unique method to learn details about the strangeness S =- 2 sector of the baryon-baryon interaction. From the free space Bonn-Jülich potentials,…

A nonrelativistic quark model evaluation of exclusive $b \to c$ semileptonic decay of triply heavy baryons and $c \to s, d$ semileptonic decay of $c b$ baryons

C. Albertus, J. M. Flynn, E. Hernández +1

We present results for exclusive $b \to c$ semileptonic decays of ground state triply-heavy baryons and for semileptonic $c \to s, d$ decays of doubly heavy ground state $c b$ baryons.…
