论文摘要
我们对中微子通量折叠的包含横截面进行了从头开始计算，该横截面是由Miniboone和T2K协作以$^{12} $ C测量的。该计算基于现实的两种和三核子的相互作用，以及具有一个和两个核子项的逼真的核电子电流，这些术语与这些相互作用始终构建并繁殖低能量的电动electroweak跃迁。数值确切的量子蒙特卡洛方法用于计算核弱响应函数，通过在初始和最终状态中充分保留多体相关性以及一体和两体当前贡献之间的多体相关性。我们使用$λ_A= 1.0 $或$ 1.15 $ GEV的偶极子形式的核子轴向形式，后者与最近的晶格QCD确定更加一致。发现计算出的横截面与Miniboone和T2K的中微子数据以及抗肿瘤小型酮数据非常吻合，从而产生了核和电动机跨能量和电动机的电动性特性的一致图像。
We carry out an ab initio calculation of the neutrino flux-folded inclusive cross sections, measured on $^{12}$C by the MiniBooNE and T2K collaborations in the charged-current quasielastic (CCQE) regime. The calculation is based on realistic two- and three-nucleon interactions, and on a realistic nuclear electroweak current with one-and two-nucleon terms that are constructed consistently with these interactions and reproduce low-energy electroweak transitions. Numerically exact quantum Monte Carlo methods are utilized to compute the nuclear weak response functions, by fully retaining many-body correlations in the initial and final states and interference effects between one- and two-body current contributions. We employ a nucleon axial form factor of the dipole form with $Λ_A = 1.0$ or $1.15$ GeV, the latter more in line with a very recent lattice QCD determination. The calculated cross sections are found to be in good agreement with the neutrino data of MiniBooNE and T2K, and antineutrino MiniBooNE data, yielding a consistent picture of nuclei and their electroweak properties across a wide regime of energy and momenta.
