DAFNE和KLOE-2
DAFNE and KLOE-2
摘要：
DAFNE对撞机位于INFN的弗拉斯卡蒂国家实验室，有两个主要的环，其中电子和正电子被存储在1.02 GeV的质心能量（phi共振质量）处进行碰撞。KLOE-2实验位于对撞机相互作用区。探测器能够观察和收集来自phi衰变的数据：带电和中性K介子对，较轻的无味介子（eta，eta '，f0，a0，omega/rho）。2013年上半年，KLOE探测器进行了升级，在设备内部的相互作用区域周围插入了新的探测器层，以提高探测器的密封性和接受度。长期停堆已被用于实施旨在改善DAFNE性能的一般合并计划。这篇文章介绍了φ工厂设置和实现的性能，在束流，光度和相关方面的KLOE-2物理程序，升级状态报告和最近的物理结果。
英文摘要：
The DAFNE collider, located in the Frascati National Laboratories of INFN, has two main rings, where electrons and positrons are stored to collide at a center of mass energy of 1.02 GeV, the phi resonance mass. KLOE-2 experiment is located at the collider interaction region. The detector is capable to observe and collect data coming from phi decay: charged and neutral kaon pairs, lighter unflavored mesons (eta, eta', f0, a0, omega/rho). In the first half of 2013 the KLOE detector has been upgraded inserting new detector layers in the inner part of the apparatus, around the interaction region in order to improve detector hermeticity and acceptance. The long shutdown has been used to undertake a general consolidation program aimed at improving the DAFNE performances. This contribution presents the phi-factory setup and the achieved performances in terms of beam currents, luminosity and related aspects together with the KLOE-2 physics program, upgrade status report and recent physics results.
