First physics results of the BM@N experiment at the Nuclotron/NICA complex are presented on π+ and K+ meson production in interactions of an argon beam with fixed targets of C, Al, Cu, Sn and Pb at 3.2 AGeV. Transverse momentum distributions, rapidity spectra and multiplicities of $π^+$ and $K^+$ mesons are measured. The results are compared with predictions of theoretical models and with other measurements at lower energies.
First Measurement of the Ar$(e,e^\prime)X$ Cross Section at Jefferson Lab
采用液氩时间投影室进行长基线和短基线中微子振荡实验的雄心勃勃的计划能否成功，将在很大程度上取决于对氩核的弱响应进行估计的精度。在杰斐逊实验室A厅的E12-14-012实验中，我们通过从高压气态氩靶散射高质量电子束来研究氩核的性质。本文给出了在入射电子能量$E=2.222$ ~GeV和散射角$θ= 15.541^\circ$下测量的$^{40}$ Ar $(e,e^{\prime})$双微分截面。这些数据涵盖了广泛的能量转移，其中准弹性散射和三角洲生产是占主导地位的反应机制。氩气的结果进行比较，我们以前报道的截面钛和碳，在相同的运动学设置。
Measuring Active-to-Sterile Neutrino Oscillations with Neutral Current Coherent Neutrino-Nucleus Scattering
轻无菌中微子已经被引入，作为$Δm^2 \sim 1$ eV $^2$处的许多振荡信号的解释。在相对较短的基线上的中微子振荡提供了对这些可能的新状态的探测。本文描述了一个基于加速器的实验，利用中性流相干中微子-核散射来严格搜索活跃到无菌的中微子振荡。因此，这个实验可以明确地确定无菌中微子的存在，并对它们的混合参数提供限制。基于回旋加速器的质子束可以被引导到多个目标，产生低能π介子和μ介子衰变静止中微子源，与单个检测器的距离可变。两种类型的探测器被认为是：基于锗的探测器的灵感来自CDMS的设计和液氩探测器的灵感来自拟议的CLEAR实验。
