标题： On the detection of neutrinos from solar flares using pion-decay photons to provide a time window template

摘要： 自八十年代末以来，针对Homestake实验中与太阳耀斑相伴的总中微子流增加的报道，太阳中微子探测器一直在寻找太阳耀斑信号。尽管这些探测器使用了不同的太阳耀斑样本和分析方法，但没有一个能够确认Homestake所观测到的可能信号。 由加速离子与太阳大气碰撞产生的介子衰变所产生的中微子，将为太阳耀斑期间强子加速和相互作用过程的基础物理提供一个新的视角。 实际上，太阳耀斑中微子流的测量将有助于限制当前的一些参数，如加速通量的组成、质子/离子能谱指数以及高能截止或相互作用区域的磁场配置。 我们在这里描述了一种新的寻找这些中微子的方法，通过考虑特定的太阳耀斑样本和数据驱动的时间窗口模板，这将提高中微子检测的可能性。 显示英文摘要

摘要： Since the end of the eighties and in response to a reported increase in the total neutrino flux in the Homestake experiment in coincidence with solar flares, solar neutrino detectors have searched for solar flare signals. Even though these detectors have used different solar flare samples and analyses, none of them has been able to confirm the possible signal seen by Homestake. Neutrinos from the decay of mesons, which are themselves produced in collisions of accelerated ions with the solar atmosphere would provide a novel window on the underlying physics of the hadronic acceleration and interaction processes during solar flares. Solar flare neutrino flux measurements would indeed help to constrain current parameters such as the composition of the accelerated flux, the proton/ion spectral index and the high energy cutoff or the magnetic configuration in the interaction region. We describe here a new way to search for these neutrinos by considering a specific solar flare sample and a data driven time window template which will improve the likelihood of neutrino detection.
