在LHC上测量分裂超对称中性子和电荷子质量

On Measuring Split-SUSY Neutralino and Chargino Masses at the LHC

N. Kersting

摘要:

在分裂-超对称模型中,在LHC能量下唯一能产生的非标准模型态是由一个胶子加上中性伴子和电荷伴子组成的,传统上认为只有后者之间的质量差才能在LHC上测量。目前的工作表明,应用一个简单的“运动学选择”技术,允许从一个事件中,在原则上完全重建中性伴子和电荷伴子质量。一个蒙特卡罗模拟证明了在大型强子对撞机上使用这种技术的可行性。

英文摘要:

In Split-Supersymmetry models, where the only non-Standard Model states produceable at LHC-energies consist of a gluino plus neutralinos and charginos, it is conventionally accepted that only mass differences among these latter are measureable at the LHC. The present work shows that application of a simple `Kinematic Selection' technique allows full reconstruction of neutralino and chargino masses from one event, in principle. A Monte Carlo simulation demonstrates the feasibilty of using this technique at the LHC.
