论文摘要
我们研究$^3P_0 $渠道中手性核力量的扰动性。在以前的工作中，重点是一杆交换，并且已显示出扰动的斜向交换的适用窗口已从阈值到质量中心动量$ k \ simeq $ 180 mev。相反，我们将检查取消短期和远程零件是否可以充分软化$^3p_0 $手性力量，以使其更适合扰动理论。结果令人鼓舞，因为总共$^3p_0 $的力显示出扰动性高达$ k \ simeq $ 280 MEV，涵盖了许多核结构计算。
We study perturbativeness of chiral nuclear forces in the $^3P_0$ channel. In previous works, the focus has been on one-pion exchange, and the applicable window of perturbative pion exchanges has been shown to span from threshold to the center-of-mass momentum $k \simeq$ 180 MeV. We will examine, instead, whether cancellation of short and long-range parts can sufficiently soften the $^3P_0$ chiral force to make it more amenable to perturbation theory. The result is encouraging, as the combined $^3P_0$ force is shown to be perturbative up to $k \simeq$ 280 MeV, covering many nuclear-structure calculations.
