高能高亮度$e^+e^-$对撞机的辐射返回能力

Radiative Return Capabilities of a High-Energy, High-Luminosity $e^+e^-$ Collider

Marek Karliner, Matthew Low, Jonathan L. Rosner, Lian-Tao Wang

摘要:

在质心能量$E_{CM}$下运行的正负电子对撞机可以通过初始态辐射(ISR或辐射返回)收集所有较低能量的事件。我们探索辐射返回研究的能力,建议高光度对撞机在$E_{CM}$ = 250或90 GeV,以填补低能量对撞机,如PEP,PETRA,TRISTAN,LEP留下的空白。这些能力相比,较低的能量$e^+e^-$对撞机,以及强子对撞机,如Tevatron和欧洲核子研究中心大型强子对撞机(LHC)。给出了暗光子搜索和重味光谱学中一些可访问的问题的例子。

英文摘要:

An electron-positron collider operating at a center-of-mass energy $E_{CM}$ can collect events at all lower energies through initial-state radiation (ISR or radiative return). We explore the capabilities for radiative return studies by a proposed high-luminosity collider at $E_{CM}$ = 250 or 90 GeV, to fill in gaps left by lower-energy colliders such as PEP, PETRA, TRISTAN, and LEP. These capabilities are compared with those of the lower-energy $e^+e^-$ colliders as well as hadron colliders such as the Tevatron and the CERN Large Hadron Collider (LHC). Some examples of accessible questions in dark photon searches and heavy flavor spectroscopy are given.
