核磁四极矩(MQM)，如基本粒子的本征电偶极矩，违反了宇称对称性和时间反转对称性，因此，探测物理超出了标准模型。报道了BaF、YBF、BaOH和YbOH中原子核MQM相互作用常数的精确的相对论耦合团簇计算。我们详细阐述了对我们结果的不确定性的估计。讨论了寻找非零核MQM的实验意义。
Nuclear magnetic quadrupole moments (MQMs), such as intrinsic electric dipole moments of elementary particles, violate both parity and time-reversal symmetry and, therefore, probe physics beyond the standard model. We report on accurate relativistic coupled cluster calculations of the nuclear MQM interaction constants in BaF, YbF, BaOH, and YbOH. We elaborate on estimates of the uncertainty of our results. The implications of experiments searching for nonzero nuclear MQMs are discussed.
