论文摘要
我们介绍了基于部分保守的轴向电流定理的形式主义在中微子核相互作用中的相干性锥形产生的研究，该定理将中微子核核横截面连接到Pion-Nucleus弹性散射横截面。使用Glauber模型计算出浦核弹性散射横截面，该模型采用三个输入，核密度，锥形核子横截面和$α_{πn} $，这是真实的比率与$πn$正向散射的想象中的比例，从测量数据中获得了参数。我们计算了中微子（抗中性） - 核核散射的电荷和中性电流相干锥形产生的差分和集成的横截面，用于从光到重型材料，例如锂，碳，碳氢化合物，氧气，氧气，氧气，硅，硅，Argon，Argon，Iron和Lead和Lead。将这些横截面计算的结果与测量数据以及Berger-Sehgal模型和Genie包的计算进行了比较。与Glauber模型计算出的横截面和测量的横截面之间有着极好的一致性。虽然Genie和Berger-Sehgal模型很好地描述了较低能量范围的数据，但本计算描述了所有能量范围中的数据。还针对中微子横截面相干区域中的Ino和Dune等即将进行的实验进行了预测。
We present a study of coherent pion production in neutrino-nucleus interactions using the formalism based on partially conserved axial current theorem which connects the neutrino-nucleus cross section to the pion-nucleus elastic scattering cross section. Pion-nucleus elastic scattering cross section is calculated using Glauber model which takes three inputs, nuclear densities, pion-nucleon cross section and $α_{πN}$ which is the ratio of real to imaginary part of $πN$ forward scattering amplitude, for which the parametrizations are obtained from measured data. We calculate the differential and integrated cross sections for charge and neutral current coherent pion production in neutrino (anti-neutrino)-nucleus scattering for a range of nuclear targets from light to heavy materials such as lithium, carbon, hydrocarbon, oxygen, silicon, argon, iron and lead. The results of these cross section calculations are compared with the measured data and with the calculations from the Berger-Sehgal model and GENIE package. There is an excellent agreement between the calculated and measured cross sections with Glauber model. While GENIE and Berger-Sehgal model give a good description of the data in the lower energy range the present calculations describe the data in all energy ranges. Predictions are also made for upcoming experiments like INO and DUNE in the coherent region of neutrino cross section.
