陀螺、极化、LHC和新物理学

Top, Polarization, LHC and New Physics

Jernej F. Kamenik

摘要:

顶夸克衰变中的极化观测值是研究重三代夸克相互作用可能的新物理贡献的敏感探针。在一个有效的理论方法,这种新的物理贡献可以分类在几个更高的维度运营商。我们调查间接约束这些运营商之间的相互作用,主要来自罕见的B物理过程,并在大型强子对撞机的顶部偏振观测的直接测量。

英文摘要:

Polarization observables in top quark decays are sensitive probes of possible new physics contributions to the interactions of the heavy third generation quarks. Within an effective theory approach such new physics contributions can be classified in terms of several higher dimensional operators. We investigate the interplay between indirect constraints on such operators, coming mainly from rare B physics processes, and direct measurements of top polarization observables at the LHC.
