First observation of $\Lambda_{b}^{0} \rightarrow \Sigma_c^{(*) } D^{(*)-} K^{-}$ decays

arXiv:2404.19510v1 Announce Type: new
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.

Kokeilin Microsoft Copilotin salakirjoituksen murtokykyjä. Ensimmäisen perusteella vaikutti lupaavalta mutta toinen paljasti sitten todelliset kyvyt.
Kieltämättä tämä demonstroi #LLM:t opettelevat "hauki on kala, hauki on kala" menetelmällä oikeasti ymmärtämättä ongelmaa.
Jälkimmäisen salakirjoitetun tekstin lähde jopa mainittiin vastauksessa mutta huti tuli.

Let’s do some arithmetic. A company takes in $4 million in total revenue. To accomplish this, it spends $62 million.
Net loss: $58 million.
