利用大亚湾和RENO对太阳能$Δm^2$的限制

Constraints on the Solar $Δm^2$ using Daya Bay & RENO

Seon-Hee Seo, Stephen Parke

摘要:

我们证明,目前正在运行的短基线反应堆实验,特别是大亚湾,可以把一个显着的上限$Δm^2_{21}$。这种新的方法来确定$Δm^2_{21}$可以与大亚湾\RENO的现有数据进行,并提供额外的信息,$Δm^2_{21}$在不同的$L/E$范围($\sim$ 0.5 km/MeV)的重要一致性检查的3味大质量中微子范例。大亚湾和RENO的上限以及大亚湾在2020年底之前可能的下限将是这个重要数量的唯一新信息,直到中基线反应堆实验JUNO在下一个十年中期提供非常精确的测量。在本研究中,$θ_{12}$值是固定的,因为其对$Δm^2_{21}$测量的影响相对较小,如附录中所述。

英文摘要:

We demonstrate that the currently running short baseline reactor experiments, especially Daya Bay, can put a significant upper bound on $Δm^2_{21}$. This novel approach to determining $Δm^2_{21}$ can be performed with the current data of both Daya Bay \& RENO and provides additional information on $Δm^2_{21}$ in a different $L/E$ range ($\sim$ 0.5 km/MeV) for an important consistency check on the 3 flavor massive neutrino paradigm. Upper limits by Daya Bay and RENO and a possible lower limit from Daya Bay, before the end of 2020, will be the only new information on this important quantity until the medium baseline reactor experiment, JUNO, gives a very precise measurement in the middle of the next decade. In this study $θ_{12}$ value is fixed since its impact on the $Δm^2_{21}$ measurement is relatively small as discussed in the Appendix.
