具有初态辐射的新物理过程的新重建技术

Novel reconstruction technique for New Physics processes with initial state radiation

Johan Alwall, Kenji Hiramatsu, Mihoko M. Nojiri, Yasuhiro Shimizu

摘要:

在强子对撞机中,新的重粒子的产生与额外的夸克和胶子有关,这些夸克和胶子具有显著的横动量。额外的喷流使新粒子质量的重建变得复杂。以大型强子对撞机上的胶子对产生和衰变为例,我们发展了一种新的技术来减少这些影响,并重建胶子衰变产物的一个清晰的运动学终点。

英文摘要:

At hadron colliders, the production of heavy new particles is associated with additional quarks and gluons with significant transeverse momentum. The additional jets complicates the reconstruction of new particle masses. Taking gluino pair production and decay at the Large Hadron Collider as an example, we develop a novel technique to reduce these effects, and to reconstruct a clear kinematical endpoint for the gluino decay products.
