在$\sqrt{s}=$ 7 TeV质子-质子碰撞中产生$Σ(1385)^{\pm}$和$Ξ(1530)^{0}$

Production of $Σ(1385)^{\pm}$ and $Ξ(1530)^{0}$ in proton-proton collisions at $\sqrt{s}=$ 7 TeV

ALICE Collaboration

摘要:

在LHC上用ALICE探测器测量了$\sqrt{s}$ = 7 TeV质子-质子碰撞中中的中快度($\left | y \right |<0.5$)奇异和双奇异重子共振($Σ(1385)^{\pm}$,$Ξ(1530)^{0}$)的产生.横向动量谱的非弹性碰撞相比,QCD启发的模型,在一般underpredict的数据。对在$Ξπ$通道中衰变的$ϕ(1860)$五夸克的搜索已经进行,但没有看到任何证据。

英文摘要:

The production of the strange and double-strange baryon resonances ($Σ(1385)^{\pm}$, $Ξ(1530)^{0}$) has been measured at mid-rapidity ($\left | y \right |<0.5$) in proton-proton collisions at $\sqrt{s}$ = 7 TeV with the ALICE detector at the LHC. Transverse momentum spectra for inelastic collisions are compared to QCD-inspired models, which in general underpredict the data. A search for the $ϕ(1860)$ pentaquark, decaying in the $Ξπ$ channel, has been carried out but no evidence is seen.
