Abstract: The four decays, $\Lambda_{b}^{0} \rightarrow \Sigma_c^{(*) } D^{(*)-} K^{-}$, are observed for the first time using proton-proton collision data collected with the LHCb detector at a centre-of-mass energy of $13\,\rm{TeV}$, corresponding to an integrated luminosity of $6\,\rm{fb}^{-1}$. By considering the $\Lambda_b^0 \rightarrow \Lambda_c^{ } \overline{D}^0 K^{-}$ decay as reference channel, the following branching fraction ratios are measured to be,
$$\frac{\cal{B} (\Lambda_{b}^{0} \rightarrow \Sigma_{c}^{ } \rm{D}^{-} {K}^{-})}{\cal{B}(\Lambda_{b}^{0} \rightarrow \Lambda_c^{ } \rm \overline{D}^0 {K}^{-})}
= {0.282}\pm{0.016}\pm{0.016}\pm{0.005},
\frac{\cal{B}(\Lambda_{b}^{0} \rightarrow \Sigma_{c}^{* } \rm {D}^{-} {K}^{-})}{\cal{B}(\Lambda_{b}^{0} \rightarrow \Sigma_c^{ } \rm {D}^{-} {K}^{-})}
= {0.460}\pm{0.052}\pm{0.028},
\frac{\cal{B}(\Lambda_{b}^{0} \rightarrow \Sigma_{c}^{ } \rm {D}^{*-} {K}^{-})}{\cal{B}(\Lambda_{b}^{0} \rightarrow \Sigma_c^{ } \rm {D}^{-} {K}^{-})}
= {2.261}\pm{0.202}\pm{0.129}\pm{0.046},
\frac{\cal{B}(\Lambda_{b}^{0} \rightarrow \Sigma_{c}^{* } \rm D^{*-} K^{-})}{\cal{B}(\Lambda_{b}^{0} \rightarrow \Sigma_c^{ } \rm D^{-} K^{-})}
= {0.896}\pm{0.137}\pm{0.066}\pm{0.018},$$
where the first uncertainties are statistical, the second are systematic, and the third are due to uncertainties in the branching fractions of intermediate particle decays. These initial observations mark the beginning of pentaquark searches in these modes, with more data set to become available following the LHCb upgrade.

QML-IB: Quantized Collaborative Intelligence between Multiple Devices and the Mobile Network
The integration of artificial intelligence (AI) and mobile networks is regarded as one of the most important scenarios for 6G. In 6G, a major objective is to realize the efficient transmission of task-relevant data. Then a key problem arises, how to design collaborative AI models for the device side and the network side, so that the transmitted data between the device and the network is efficient enough, which means the transmission overhead is low but the AI task result is accurate. In this pa…

Scientists from Prague are expanding the possibilities of using RNA in gene medicine
Dr. Petr Cígler and his collaborators are working on refining molecular systems for transporting ribonucleic acid (RNA) molecules into cells. The question of how to effectively deliver RNA to a designated place in the body in order to silence a malfunctioning gene is one of the greatest challenges of the rapidly developing field of gene medicine.

Measurement of $Ω^0_{\rm c}$ baryon production and branching-fraction ratio ${\rm BR(Ω^0_c \rightarrow Ω^- e^+ν_e)} / {\rm BR(Ω^0_c \rightarrow Ω^- π^+)}$ in pp collisions at $\sqrt{s}$ = 13 TeV
The inclusive production of the charm-strange baryon $Ω^{0}_{\rm c}$ is measured for the first time via its semileptonic decay into $Ω^{-}\rm e^{+}ν_{e}$ at midrapidity ($|y|<0.8$) in proton$-$proton (pp) collisions at the centre-of-mass energy $\sqrt{s}=13$ TeV with the ALICE detector at the LHC. The transverse momentum ($p_{\rm T}$) differential cross section multiplied by the branching ratio is presented in the interval $2
