补充以前的理论和实验工作，我们探讨了新类型的短程修改所产生的时空对称性破缺的牛顿引力。第一个非微扰，即洛伦兹对称性破缺系数的所有阶数，都是在牛顿极限下构造的。我们利用一般的破缺项修改重力扇区，并检查各向同性系数的限制。结果表明，新的力法修正，超越了标准的汤川参数化。此外，存在系数值的范围，其可以使所产生的力在短距离处比牛顿预测大。实验信号进行了讨论，为典型的测试质量安排。
Complementing previous theoretical and experimental work, we explore new types of short-range modifications to Newtonian gravity arising from spacetime-symmetry breaking. The first non-perturbative, i.e. to all orders in coefficients for Lorentz-symmetry breaking, are constructed in the Newtonian limit. We make use of the generic symmetry-breaking terms modifying the gravity sector and examine the isotropic coefficient limit. The results show new kinds of force law corrections, going beyond the standard Yukawa parameterization. Further, there are ranges of the values of the coefficients that could make the resulting forces large compared to the Newtonian prediction at short distances. Experimental signals are discussed for typical test mass arrangements.
