B -> D τ nu中τ的纵向极化及其在寻找带电希格斯玻色子中的作用

Tau longitudinal polarization in B -> D tau nu and its role in the search for charged Higgs boson

Minoru Tanaka, Ryoutaro Watanabe

摘要:

本文研究了τ轻子在B → D τ nu衰变中的纵向极化。在讨论了τ衰变模式对τ极化的可能敏感性之后,我们研究了带电希格斯玻色子玻色子对B -> D τ nu中τ极化的影响。我们发现衰变率和τ极化之间的关系,并澄清τ极化测量在寻找带电希格斯玻色子的作用。

英文摘要:

We study the longitudinal polarization of the tau lepton in B -> D tau nu decay. After discussing possible sensitivities of tau decay modes to the tau polarization, we examine the effect of charged Higgs boson on the tau polarization in B -> D tau nu. We find a relation between the decay rate and the tau polarization, and clarify the role of the tau polarization measurement in the search for the charged Higgs boson.
