# Excited doubly heavy baryons production via Higgs decays

Dec 2022

Through the interaction of Higgs with heavy quarks in standard model, we havesystematically studied and predicted the production of excited doubly heavybaryons based on non-relativistic QCD theory. The decay widths, differentialdistributions, and major theoretical uncertainties of the excited doubly heavybaryons via the process $H \rightarrow \langle QQ'\rangle[n] \rightarrow\Xi_{QQ'}+ \bar {Q'} + \bar {Q}$ are discussed in detail. The spin and colorquantum number of the intermediate $P$-wave diquark state $\langleQQ'\rangle[n]$ can be $\langle cc\rangle[^{1}P_{1}]_{\mathbf{\bar 3}}$,$\langle cc\rangle[^{3}P_{J}]_{\mathbf{6}}$, $\langlebc\rangle[^{1}P_{1}]_{\mathbf{\bar 3}/ \mathbf{6}}$, $\langlebc\rangle[^{3}P_{J}]_{\mathbf{\bar 3}/ \mathbf{6}}$, $\langle bb\rangle[^{1}P_{1}]_{\mathbf{\bar 3}}$ and $\langlebb\rangle[^{3}P_{J}]_{\mathbf{6}}$, with $J=0, 1, 2$. The contributions fromall summed $P$-wave states can be about $3.05\%$, $3.23\%$ and $2.19\%$ of the$S$-wave states for the production of $\Xi_{cc}$, $\Xi_{bc}$ and $\Xi_{bb}$,accordingly. Therefore, there will be about 0.41$\times10^4$ events of$\Xi_{cc}$, 6.35$\times10^4$ events of $\Xi_{bc}$ and 0.28$\times10^4$ eventsof $\Xi_{bb}$ produced per year at the HL-LHC, and a smaller number of eventswould be produced at the CEPC or ILC but with a cleaner background to bemeasured by the experiments.
