论文摘要
在本文中,我们研究了KM3NET设施的不同长基线实验选项的能力,即P2O,P2O,升级P2O和P2SO以探测光无菌中微子,并将其敏感性与Dune进行比较。 P2O选项将在Orca检测器上检测到Protvino的90 kW束的中微子,升级后的P2O将具有从升级的450 kW梁的中微子,可在Orca检测器中检测到,并且该选项P2SO将从450 kW beam中探测到450 kW beam to the the Up-Superca检测器。所有这些选项的基线在2595公里左右。我们的结果表明,如果$δm^2_ {41} $的值约为10(1)EV $^2 $,则KM3NET(Dune)的实验将更加敏感。我们的结果还表明,近检测器的作用对于研究无菌中微子和近探测器的添加非常重要,与仅在3+1场景中仅远检测器相比,敏感性提高了灵敏度。在KM3NET的三个选项中,P2O和升级的P2O的灵敏度受到限制,P2SO的灵敏度可比较或更好。
In this paper, we study the capability of different long-baseline experiment options at the KM3NeT facility i.e., P2O, Upgraded P2O and P2SO to probe the light sterile neutrino and compare their sensitivities with DUNE. The P2O option will have neutrinos from a 90 KW beam at Protvino to be detected at the ORCA detector, the Upgraded P2O will have neutrinos from the upgraded 450 KW beam to be detected at the ORCA detector and the option P2SO will have neutrinos from a 450 KW beam to be detected at the upgraded Super-ORCA detector. All these options will have a baseline around 2595 km. Our results show that the experiments at the KM3NeT (DUNE) would be more sensitive if the value of $Δm^2_{41}$ is around 10 (1) eV$^2$. Our results also show that the role of near detector is very important for the study of sterile neutrinos and addition of near detector improves the sensitivity as compared to only far detector for 3+1 scenario. Among the three options at KM3NeT, the sensitivity of P2O and upgraded P2O is limited and sensitivity of P2SO is either comparable or better than DUNE.
