Description
Two-neutrino double electron capture (2$\nu$DEC) is a second-order weak interaction process. The half-life of 2$\nu$DEC is directly related to that of neutrino-less double electron capture (0$\nu$DEC) and is of significant importance for revealing the Majorana nature of neutrinos. PandaX-4T is a time projection chamber with 3.7 tons of natural xenon in the active volume, which contains approximately 3.7 kg of Xe-124, a DEC isotope. Using the 655.6 tonne-days of PandaX-4T commissioning Run and the science Run 1 data, we have achieved a precise determination of the 2$\nu$DEC half-life for Xe-124 and searched for possible 0$\nu$DEC signal.
