本文报道了利用ATLAS实验研究碰撞中底夸克标量对产生的结果。标量底夸克是在有大的横向动量缺失和两个末态喷流的事件中寻找的，这两个喷流都被确定为起源于底夸克。在非宇称守恒最小超对称情形下，假定标量底夸克完全衰变为底夸克和中性诺，在b˜1-χ˜10质量面上获得了95%的置信度上限，使得对于小于60GeV的中性诺质量，直到390GeV的标量底质量被排除在外。
The results of a search for pair production of the scalar partners of bottom quarks inofcollisions atusing the ATLAS experiment are reported. Scalar bottom quarks are searched for in events with large missing transverse momentum and two jets in the final state, where both jets are identified as originating from a bottom quark. In an-parity conserving minimal supersymmetric scenario, assuming that the scalar bottom quark decays exclusively into a bottom quark and a neutralino, 95% confidence-level upper limits are obtained in the b˜1-χ˜10 mass plane such that for neutralino masses below 60 GeV scalar bottom masses up to 390 GeV are excluded.
