Experimental Study of Heavy Quark Decays

该提案概述了两项旨在通过弱相互作用研究重夸克衰变的活动。这名研究人员加入了费米实验室（E791）的一个合作实验，该实验旨在通过介子核碰撞产生大量包含粲夸克的介子。她的任务是研究这些介子半光子衰变的形式因素，以及D0和D0混合的可能性——这种现象已经在奇异和底夸克介子中观察到。PI还建议她继续参与研究和开发可能演变的实验，旨在研究b夸克弱衰变中的CP破坏。这个实验将围绕一个产生大量B介子的非对称e+e加速器装置展开，这个装置被称为B工厂。她已经参与了与使用这种设施有关的探测器开发工作，并建议继续特别评价氦气漂移室。

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.
