| contents | Electric charge conservation (ECC) is typically taken as an axiom in the standard model. Searching for small violations with high-performance experiments could lead us to new physics. In this work, we tested ``invisible" electric charge nonconservation (ECNC) events with 1.16 ton$\cdot$year electron recoil data from the XENON-nT experiment. There was no statistically significant signal, and the ECNC limit was updated to $τ(e^-\rightarrow{ν_e+\barν_e+ν_e}) > 4.34 \times10^{27}$ yr. This work increases the limit by two orders of magnitude and shows that dark matter direct detection experiments have great potential for further ECC testing. |
