论文摘要
相对质量中心的能量分布在$ e^+e^ - $ colliders约为$ 10^{ - 3} $,它比窄共振的宽度J/$ψ$,$ψ$(2s),$υ$(1S),$υ$(1S),$υ$(2S),$(3S),$(3S)Mesons,Tauonium和其他。它的减少将大大提高共振率,并为寻找新物理学的巨大机会提供了巨大的机会。在本文中,我们为具有较大交叉角度的山脉(可以提供高光度)提出了一种新的单色化方法。通过在相互作用点引入适当的能量角相关性,取消了梁能量扩散对质量中心能量扩散的贡献;出现$σ_W/w \ sim(0.5-1)10^{ - 5} $。
The relative center-of-mass energy spread at $e^+e^-$ colliders is about $10^{-3}$, which is much larger than the widths of narrow resonances J/$ψ$, $ψ$(2S), $Υ$(1S), $Υ$(2S), $Υ$(3S) mesons, tauonium and some others. It's reduction would significantly increase the resonance production rates and open up great opportunities in the search for new physics. In this paper, we propose a new monochromatization method for colliders with a large crossing angle (which can provide a high luminosity). The contribution of the beam energy spread to the spread of the center-of-mass energy is canceled by introducing an appropriate energy-angle correlation at the interaction point; $σ_W/W \sim (0.5-1)10^{-5}$ appears possible.
