Experimental Study of Heavy Quark Decays

该提议概述了两项活动，这两项活动都是为了研究通过弱相互作用的重夸克的衰变。这位研究人员已经加入了费米实验室(E791)的一个合作实验，该实验旨在从介子核碰撞中产生大量包含迷人夸克的介子。她在这方面的作用是研究这些介子的半轻子衰变中的形状因子，以及D0和D0反D0混合的可能性-这一现象已经在奇怪的和底夸克介子对应物中观察到。PI还建议继续参与一项实验的可能演变所需的研究和开发，该实验旨在研究b夸克弱衰变中的CP破坏。这项实验将围绕一个不对称的电子加速器设备进行，该设备生产大量的B介子，被称为B工厂。她已经参与了与使用这种设施相关的探测器开发，并建议继续特别评估氦气体漂移室。

The proposal outlines two activities both of which are aimed at a study of decays of heavy quarks through the weak interaction. The investigator has joined a collaboration in an experiment at Fermilab (E791) aimed at the production from pion nucleus collisions of large numbers of mesons containing the charmed quark. Her role in this is to study form factors in semileptonic decays of these mesons, and also the possibility of D0 anti D0 mixing - a phenomenon which has already been observed in the strange and bottom quark mesonic counterparts. The PI also proposes to continue her involvement in the research and development required in the possible evolution of an experiment aimed at a study of CP violation in the weak decays of b quarks. This experiment would center about an asymmetric e+e- accelerator facility producing large numbers of B mesons known as a B Factory. She is already involved in detector development relevant to the use of such a facility, and proposes to continue to evaluate Helium gas drift chambers in particular.
