Borexino是位于意大利Gran Sasso国家实验室地下的液体闪烁体探测器。到今年年底，它的物理项目主要集中在太阳中微子的研究上，特别是来自铍、pp、pep和CNO的聚变反应。了解太阳的反应链可以为天体物理学（恒星物理学、恒星形成等）、天体粒子和粒子物理学等物理学科提供见解。第二阶段于2011年开始，其目的是改进第一阶段的结果，特别是对pep和CNO过程的中微子通量的测量。到今年年底，从太阳获取的数据将会结束，一个新的项目将会启动：用boreXino进行短距离振荡（SOX），它使用一个中微子的铈源（100÷150 kCi的活动），旨在确认或排除无菌中微子的存在。这种粒子被假设为证明发现的反应堆、镓和LSND异常是正确的，并且可以拒绝标准模型的扩展。这项工作是迄今为止所取得的太阳中微子结果的总结，它不仅导致了对太阳过程的精确研究，而且还导致了更多的标准模型导向的测量（如电荷的稳定性，即电子的寿命）。此外，还讨论了SOX程序的前景，显示了对几乎完全覆盖异常中微子实验首选区域的第四个中微子态的实验灵敏度，以及探测器在地源中微子研究等方面的其他应用。
Borexino is a liquid scintillator detector sited underground in the Laboratori Nazionali del Gran Sasso (Italy). Its physics program, until the end of this year, is focussed on the study of solar neutrinos, in particular from the Beryllium, pp, pep and CNO fusion reactions. Knowing the reaction chains in the sun provides insights towards physics disciplines such as astrophysics (star physics, star formation, etc.), astroparticle and particle physics. Phase II started in 2011 and its aim is to improve the phase I results, in particular the measurements of the neutrino fluxes from the pep and CNO processes. By the end of this year, data taking from the sun will be over and a new project is scheduled to launch: Short distance Oscillation with boreXino (SOX), which uses a Cerium source for neutrinos (100÷150 kCi of activity) and aims to confirm or rule out the presence of sterile neutrinos. This particle is hypothesised to justify the reactor, Gallium and LSND anomalies found and can reject extensions to the standard model. The work presented is a summary of the solar neutrino results achieved so far, which lead not only to a precise study of the processes in the sun, but also to more Standard Model oriented measurements (such as the stability of the charge, i.e. the life time of the electron). Furthermore, the perspectives of the SOX program are discussed showing the experiment sensitivity to a fourth neutrino state covering almost entirely 3σ of the preferred region of the anomalous neutrino experiments, and additional applications of the detector such as the study of geo-neutrinos.
