Title: Search for a resonance decaying into a scalar particle and a Higgs boson in the final state with two bottom quarks and two photons with 199 fb$^{-1}$ of data collected at $\sqrt{s}$=13 TeV and $\sqrt{s}$=13.6 TeV with the ATLAS detector Show Chinese title

Title: 在最终状态包含两个底夸克和两个光子的情况下，搜索衰变为标量粒子和希格斯玻色子的共振现象，使用在$\sqrt{s}$=13 TeV 和$\sqrt{s}$=13.6 TeV 能量下由 ATLAS 探测器收集的 199 fb$^{-1}$数据

Abstract: A search for the resonant production of a heavy scalar $X$ decaying into a Higgs boson and a lighter scalar $S$, through the process $X \rightarrow S (\rightarrow b \bar{b})H ( \rightarrow \gamma\gamma)$, where the two photons are consistent with the Higgs boson decay, is performed. The search is conducted using integrated luminosities of 140 fb$^{-1}$ and 58.6 fb$^{-1}$ of proton-proton collision data at centre-of-mass energies of 13 TeV and 13.6 TeV respectively, recorded with the ATLAS detector at the Large Hadron Collider. The search is performed over the mass ranges of 170 $\leq$ $m_{X}$ $\leq$ 1000 GeV and 15 $\leq$ $m_{S}$ $\leq$ 500 GeV. No significant excess over the Standard Model background prediction is observed and limits at 95% confidence level are set on the cross-section times branching ratio $\sigma(X \rightarrow S (\rightarrow b \bar{b})H ( \rightarrow \gamma\gamma))$ at 13 TeV, ranging from 9 fb to 0.06 fb.

Abstract: 对通过过程$X \rightarrow S (\rightarrow b \bar{b})H ( \rightarrow \gamma\gamma)$产生一个重标量$X$并衰变为一个希格斯玻色子和一个较轻的标量$S$的共振生产进行搜索，其中两个光子与希格斯玻色子衰变一致。该搜索使用了在质心系能量分别为13 TeV和13.6 TeV下由ATLAS探测器记录的质子-质子碰撞数据，积分亮度分别为140 fb$^{-1}$和58.6 fb$^{-1}$。 在170 $\leq$ $m_{X}$ $\leq$ 1000 GeV和15 $\leq$ $m_{S}$ $\leq$ 500 GeV的质量范围内进行搜索。 未观察到超过标准模型背景预测的显著过量，在95%置信度下对13 TeV下的截面乘以分支比 $\sigma(X \rightarrow S (\rightarrow b \bar{b})H ( \rightarrow \gamma\gamma))$设定了限制，范围从9 fb到0.06 fb。
