标题： Short-range forces due to Lorentz-symmetry violation

摘要： 补充之前理论和实验工作，我们探讨了由于时空对称性破缺而产生的新型短程引力修正。 在牛顿极限中，构建了非微扰的，即对洛伦兹对称性破缺系数的所有阶都有效的情况。 我们利用了修改引力部分的一般对称性破缺项，并检验了各向同性系数极限。 结果表明出现了新的力定律修正，超越了标准的杨-米尔斯参数化。 此外，存在某些系数值范围，使得在短距离下产生的力相对于牛顿预测显著增大。 讨论了典型测试质量配置的实验信号。 显示英文摘要

摘要： 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.
