Abstract

Precise measurement of the Dalitz plot parameters of the decay gives a better insight of the dynamics of the heavy pseudo-scalar meson. Various measurements of the Dalitz plot parameters of the meson have been performed with the detection of all the final state particles including the neutral decay of 2 . In many experiments, reconstruction of the meson from the neutral decay modes comes with the disadvantage of poor resolution and low efficiency compared to that of the charged particles. In this article, a study of the Dalitz plot parameters keeping the meson as a missing particle is presented. The method is found to be advantageous in the case of poor photon resolution. Effect of the charged particle resolution on the Dalitz variable Y is also examined. This work may provide guidance to select a suitable method for the Dalitz plot analysis, depending on the detector resolution. Received: 27 June 2017, Accepted: 9 October 2017; Edited by: D.

对达利茨图参数测量方法的改进

精确测量衰变的Dalitz图参数可以更好地了解重伪标量介子的动力学。对介子的Dalitz图参数进行了各种测量，检测到了包括2的中性衰变在内的所有最终状态粒子。在许多实验中，与带电粒子相比，从中性衰变模式重建介子具有分辨率差和效率低的缺点。本文研究了保持介子为缺失粒子的Dalitz图参数。发现该方法在光子分辨率差的情况下是有利的。还考察了带电粒子分辨率对Dalitz变量Y的影响。这项工作可以为根据探测器分辨率选择合适的Dalitz图分析方法提供指导。接收日期：2017年6月27日，接收日期：2018年10月9日；编辑：D.Restrepo；DOI：http://dx.doi.org/10.4279/PIP.090009引用自：S Ghosh，A Roy，《物理学论文》9，090009（2017）这篇由S Ghosha Roy撰写的论文根据知识共享归因许可证3.0获得许可。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
