CMS合作设计了一种新的事件数据格式并制作了原型，以满足大部分物理分析(至少50%)的需求，每个事件的大小为1kB。这种新格式比MINIAOD格式小20倍以上，并且只包含通常在分析的最后步骤中使用的顶级信息。讲座将从CMS的事件格式(包括摘要和诸如RECO、AOD、MINIAOD、NANOAOD等格式)的角度审查当前的分析战略，并将介绍新的NANOAOD格式的设计准则。
A new event data format has been designed and prototyped by the CMS collaboration to satisfy the needs of a large fraction of physics analyses (at least 50%) with a per event size of order 1 kB. This new format is more than a factor of 20 smaller than the MINIAOD format and contains only top level information typically used in the last steps of the analysis. The talk will review the current analysis strategy from the point of view of event format in CMS (both skims and formats such as RECO, AOD, MINIAOD, NANOAOD) and will describe the design guidelines for the new NANOAOD format.
